Work by USGS oceanographer Juliette Finzi Hart is featured in an Orange County Register article published February 14, “How scientists are using virtual reality to show people effects of global warming”. Finzi Hart played a major role in creating virtual-reality viewers to help visitors envision the effects of sea-level rise and storms on Santa Monica beach. She is using a device on loan from Google to create 360-degree videos of flooding by extreme high tides (“king tides”) in various parts of Southern California. Available on YouTube, the videos enable viewers to see the kind of flooding likely to occur as sea level continues to rise. On February 24, Finzi Hart will present her work to the region’s South Bay Cities Council of Governments. Contact: Juliette Finzi Hart, email@example.com, 831-460-7522

A post-storm survey of beaches in Santa Cruz, California, by USGS researchers prompted numerous stories in the local media. On January 12-13, scientists from the Pacific Coastal and Marine Science Center mapped beaches and the seafloor around the mouths of two rivers to measure sediment washed to the coast by heavy rainfall (see next news item, below). Four TV stations filmed surveying on the morning of January 13: KPIX (CBS), ABC, KSBW (no link available), and KION. By January 23, project leader Patrick Barnard had given additional interviews to the Santa Cruz Sentinel and the Good Times, and a second interview to KSBW.

On January 12-13, just days after “atmospheric river” storms dropped heavy rain on Santa Cruz, California, scientists from the USGS Pacific Coastal and Marine Science Center surveyed local beaches to compile a three-dimensional map of storm-related changes. Using a laser scanner, GPS-equipped backpacks, and a sonar-equipped boat and personal watercraft, they measured the beaches and seafloor around the mouths of the San Lorenzo River and Soquel Creek. Early results show the storms washed approximately 100,000 cubic meters (about 10,000 dump-truck loads) of sand to each river mouth. The added sediment built temporary bars, which enhanced local surfing spots. In the long term, the sand should help protect beaches and developed bluffs and shoreline. The fieldwork complements twice-a-year surveys from Santa Cruz to Moss Landing. The research results should assist communities planning for sea-level rise and other coastal hazards.

Juliette Finzi Hart, USGS, shows how much flooding a large storm combined with future sea-level rise would likely cause in the ports of Los Angeles and Long Beach.
Juliette Finzi Hart of the USGS Pacific Coastal and Marine Science Center used virtual reality to show how future storms and sea-level rise are likely to change the shoreline at Long Beach, California. She was part of a public forum at the Aquarium of the Pacific on January 21, 2017, sponsored by the aquarium and the League of Women Voters. Finzi Hart described coastal flooding projected by the USGS Coastal Storm Modeling System (CoSMoS) and showed images of the prior week’s “king tides,” or highest high tides of the year. Today’s extreme high tides will be tomorrow’s average daily high tide, and they help the CoSMoS group validate model projections for future sea-level rise.

Residents and visitors both revel in Kauai’s lush landscape, and beneath its seascape. However, it’s underwater where things don’t look so healthy—at least not here at Makua Beach.
Scientists from the U.S. Geological Survey got a detailed picture of the coral reef’s physical environment. Understanding just what these reefs are exposed to and for how long, may help explain why some corals here have succumbed to black band disease.

Scientists from the USGS Pacific Coastal and Marine Science Center and California Water Science Center worked day and night January 7-9 to collect samples of sediment-laden water from the flooding San Lorenzo River. It was the third high flow in a three-week period. From a pedestrian bridge in downtown Santa Cruz, they collected more than 20 samples for measurement of sediment content. The work is part of a multiyear study of how conditions in the watershed—such as total rainfall and recent flooding and drought history—affect the amount of sediment washed to the coast. Answers will help coastal and water-resource managers understand how watershed sediment output, along with the amount of sediment-associated pollutants, may change along California’s coast with year-to-year variations in storm frequency and intensity during an era of changing climate.

USGS scientists and colleagues held a workshop to share recently acquired marine data on the Queen Charlotte-Fairweather fault in southeast Alaska and to plan 2017 research cruises. Participants from USGS, Geological Survey of Canada, Sitka Sound Science Center, Moss Landing Marine Lab, and Friday Harbor Laboratories met October 25-29, 2016, on Orcas Island, Washington.
Like California’s San Andreas fault, the Queen Charlotte-Fairweather fault (QCFF) is a strike-slip fault separating the Pacific and North American tectonic plates. The QFCC lies mostly offshore southeast Alaska and British Columbia. It has experienced seven major earthquakes in the past 100 years, including a 1949 magnitude-8.1 event, Canada’s largest recorded earthquake.
The workshop participants are collaborating to fill gaps in knowledge about this extremely active fault and the hazards it poses to communities in Alaska and Canada.

Visitors to the Santa Monica Pier in southern California can now see what the beach might look like when future storms and sea-level rise raise water levels. Two virtual-reality viewers, named “Owls” for their distinctive appearance, show the projected extent of flooding by a big storm at high tide, by sea-level rise, and by both together. The projections come from the USGS Coastal Storm Modeling System (CoSMoS). The viewers also show how communities can adapt to sea-level rise through nature-based coastal-planning projects, such as enhanced dunes. The City of Santa Monica developed the Owls (one ADA-accessible) in partnership with the USGS, Owlized, and the USC Sea Grant program. The Owls will operate from November 7, 2016, to January 7, 2017; a public celebration was held November 16 to coincide with “King” high tides.

A camera crew from CBS This Morning visited the USGS Pacific Coastal and Marine Science Center on November 10, 2016, to interview Janet Watt about her discovery of a connection between the Hayward and Rodgers Creek faults, two of the most hazardous earthquake faults in California’s San Francisco Bay area. In addition to a sit-down interview, they filmed Watt and her team—Mary McGann, Katie Maier, and Tom Lorenson—processing sediment cores collected along the fault beneath San Pablo Bay. CBS News correspondent Mireya Villareal asked about what led to the discovery, what it means for Bay Area earthquake hazards, and how the team plans to use microfossils from the cores to date movement on the newly discovered fault strand.

A new video, “Breaking Down Reefs, Building Up Beaches,” follows coral reef experts from the USGS and the University of Western Australia as they conduct the largest-ever hydrodynamic study of how coral reefs shape coasts. The scientists spent two weeks in May 2016 installing instruments to measure currents and sediment movement in and around Australia’s largest fringing reef, in the Ningaloo Coast UNESCO World Heritage Site, Western Australia. Over the next two months, the instruments collected massive amounts of data that will give scientists great insight into the protective role of reefs and will help the USGS forecast what could happen to U.S. fringing reefs in the face of climate change and sea-level rise.

From September 11 to October 5, 2016, USGS scientists used high-resolution sonar to map the seafloor and image bubbles from natural gas seeps near Santa Barbara, California. They also collected high-resolution seismic profiles of sub-seafloor sediment layers. They are investigating the causes and history of underwater landslides, which can damage offshore oil platforms and pipelines, and generate local tsunamis. The scientists worked from two research vessels: the R/V Snavely (USGS) and the R/V Shearwater (NOAA Channel Islands National Marine Sanctuary). They will combine the new data with older data to evaluate changes in seafloor topography and to map active faults, old and new landslides, and oil and gas pathways that could weaken slopes and set them up for future slides. The team plans to present preliminary results at the 2016 AGU Fall Meeting in December. Contact: Jared Kluesner, firstname.lastname@example.org, 831-460-7547.

On October 28, 2016, Warrick met Andria Borba of KPIX 5, a CBS affiliate, at Fort Funston. He showed her how easily the cliff crumbles, explained how overlapping photos enabled his team to measure erosion rates, and noted that the results can help scientists forecast future erosion. “Geologists Get 3-D Pictures Of Beach Erosion On California Coast,” aired that night and on the web. A recent press release and journal article by Warrick and others prompted the interview. Contact: Jon Warrick, email@example.com, 831-460-7569.
On research vessel Retriever (right), USGS scientists led by Janet Watt (left) collected core samples of bayfloor sediment along the Hayward-Rodgers Creek fault zone in San Pablo Bay, California, to investigate the history of faulting beneath the bay.
From October 17-21, 2016, USGS scientists collected 20 core samples of bayfloor sediment along the Hayward-Rodgers Creek fault zone in San Pablo Bay, a northern extension of San Francisco Bay, California. The longest core measures nearly 4 meters. Detailed radiocarbon dating of benthic forams (one-celled microorganisms) in the core samples will aid in unraveling the history of faulting in the bay and constraining the age of the most recent surface-rupturing earthquake along this part of the fault zone. Recent high-resolution acoustic imaging revealed a direct link between the Hayward and Rodgers Creek faults and provided a framework for targeted sampling of offset sediment layers, unconformities, and peculiar gas pockets.

U.S. Geological Survey scientists and their coauthors from the California Coastal Records Project have found a way to use historical aerial photographs to accurately measure coastal erosion. Applying a low-cost technique called “structure-from-motion” to five sets of oblique aerial photos spanning the years 2002 to 2010, the scientists measured the volume of material eroded from coastal cliffs at Fort Funston, on the westernmost edge of San Francisco. Their results were published October 21, 2016 in the Journal of Coastal Research. Quantifying coastal change is essential for calculating trends in erosion, evaluating processes that shape coastal landscapes, and predicting how the coast will respond to future storms and sea-level rise, all critical for communities along the California coast.

Above, right: Variations in gravity caused by differences in rock density under the bay. Sharp change in gravity values (dashed white line) lies close to sites where seismic-reflection profiles imaged the Hayward fault (plus signs).
USGS scientists used a suite of complementary techniques to image sediment layers beneath San Pablo Bay, California, revealing an active fault beneath the bay that links two of the most urbanized and hazardous strike-slip faults in the San Francisco Bay area. The discovery, first announced December 2015 at the American Geophysical Union Fall Meeting, is detailed in “Missing Link between the Hayward and Rodgers Creek Faults,” published October 19, 2016, in Science Advances. Longer fault ruptures produce larger earthquakes, so understanding how fault segments connect with one another is critical to assessing the earthquake hazards they pose. This study demonstrates the importance of integrated, high-resolution mapping of sub-seafloor layers for characterizing the often-subtle deformations (as small as a few centimeters) where fault segments meet.

USGS geologist Amy East was delighted to observe a Chinook salmon carcass upstream from two dams recently removed from the Elwha River in Washington State. River restoration has allowed salmon to reach upstream spawning grounds for the first time in more than a century.
For the first time in more than a century, salmon have reached stretches of the Elwha River upstream from two dams built in the early 1900s and recently removed. In August 2016, fisheries biologists observed live salmon there. In September 2016, USGS scientists doing topographic surveys found carcasses of Chinook salmon that died after migrating from the ocean to above the upper dam site, completing their natural life cycle. Although dam removal concluded in 2014, a boulder jam remained a fish barrier until fall 2015, when NPS dynamited the boulders. Now, fish are migrating into the upper watershed—a huge success for the Elwha River Restoration Project, recently honored as a finalist for the international Riverprize. Monitoring ecosystem recovery in the Elwha is a cooperative effort by Olympic National Park, Lower Elwha Klallam Tribe, U.S. Fish and Wildlife Service, USGS, NOAA, and Washington Department of Fish and Wildlife.

USGS science turned up in an unexpected place: The Hollywood Reporter, which ran the story “Underwater in 40 Years? Which L.A. Beach Homes Are at Risk” in its August 12, 2016, issue. The piece describes how projected sea-level rise could inundate expensive areas and homes, and how flooding could be higher during a major winter storm. The reporter relied on data and maps from the USGS Coastal Storm Modeling System (CoSMoS). CoSMoS makes detailed long-range forecasts of coastal erosion and flooding caused by climate change, sea-level rise, and storms. Several California agencies used preliminary results from a CoSMoS update to plan for possible storm flooding and erosion during last year’s El Niño.

In the last two weeks of August 2016, USGS scientists from the Pacific Coastal and Marine Science Center will collect bathymetric (seafloor depth) and topographic (land elevation) data from Washington and Oregon beaches near the mouth of the Columbia River. The data will help them document the effect of the recent El Niño on Pacific Northwest beaches as well as monitor long-term coastal changes. One goal of monitoring is to determine whether sediment dredged from the river's navigation channel and placed on the seabed is helping to counter beach and jetty erosion. The USGS is working closely with the states of Washington and Oregon, the U.S. Army Corps of Engineers, and Oregon State University to provide decision makers with the best available scientific information on sediment management.

Scientists from the Pacific Coastal and Marine Science Center are mapping shallow sediment layers along the Queen Charlotte-Fairweather fault offshore southeast Alaska from August 8-24 (see more details on the Field Activity page). The seaward side of this major earthquake fault moves northwest relative to the landward side at an average rate of about 2 inches per year. This fast slip rate provides a rare opportunity to document deformation caused by individual earthquakes, and examine fault evolution in areas that have generated large historical earthquakes. In May and June, USGS scientists mapped approximately 200 miles of the seafloor along the fault for the first time. They used data from that survey to choose targets for the current survey.

The privately owned R/V Norseman steamed to the location and found three people stranded on a rocky beach after capsizing a skiff in the surf. Three Norseman crewmembers deployed a rubber raft to rescue the boaters. Due to the large swells, one of the crew swam to the beach and pulled the victims to the raft one by one in survival suits. Soon the boaters were aboard Norseman, wrapped in blankets and drinking hot coffee. After dropping the boaters off in Seward, the scientists departed for their two-week cruise to map a major earthquake fault off southeast Alaska. Learn more about the USGS research cruise.
USGS Scientists Dr. Pamela Swarzenski (left) and Dr. William Waite making measurements on sediment cores recovered from Indian Ocean during the National Gas Hydrate Program Expedition 02.
USGS scientists from the Central Energy Resources Science Center, the Woods Hole Science Center, and the Pacific Coastal and Marine Science Center assisted the Government of India in the discovery of large, highly enriched accumulations of natural gas hydrate in the Bay of Bengal. This is the first discovery of its kind in the Indian Ocean that has the potential to be producible. Natural gas hydrates are a naturally occurring, ice-like combination of natural gas and water found in the world’s oceans and polar regions. The amount of gas within the world’s gas hydrate accumulations is estimated to greatly exceed the volume of all known conventional gas resources.

In Icy Bay, Alaska, photograph of Taan Fiord base camp near sea level with the 18,000' Mt. St. Elias in the background. The tent is pitched on one to two meters of 8-month-old tsunami deposits. Much of the barren landscape was former forest.
Southeast Alaska’s 18,000-foot Mount Saint Elias rises behind a USGS tent pitched on sandy gravel left by a tsunami 8 months ago. On October 17, 2015, a rain-soaked mountainside slid into Taan Fiord on Icy Bay, sending a giant wave more than 500 feet up the opposite slope. Large tracts of barren landscape along the fiord margins used to be forest. USGS scientists study recent tsunami deposits to better understand how tsunamis work, recognize ancient tsunami deposits, and improve natural-hazard assessments.

Recent research outlines the severe consequences that bottom trawling has on loose sediment on the ocean floor. Bottom trawling is a widespread industrial fishing practice that involves dragging heavy nets, large metal doors, and chains over the seafloor to catch fish. Although previous studies have documented the direct impacts of bottom trawling on corals, sponges, fishes, and other animals, an understanding of the global impact of this practice on the seabed remained unclear until now. The first calculation of how much of the seabed is resuspended (or stirred up) by bottom-trawling shows that the sediment mass is approximately the same as the amount of all sediment being deposited on the world’s continental shelves by rivers each year (almost 22 gigatons).

USGS scientists focused on understanding the link between land-based pollutants and coral reef health along the coast of west Maui in the Hawaiian Islands. Many reefs in this area are being overgrown by invasive seaweeds, a concern since the late 1980s. The algal growth has been linked to pollutants from the land, including elevated levels of nutrients—such as nitrogen and phosphorus—in water from wastewater injection wells. This nutrient-rich water enters the groundwater system and then discharges into the ocean near the reefs. In 2014, the federal district court in Honolulu ruled that Maui County’s use of injection wells at the Lahaina Wastewater Reclamation Facility violates the federal Clean Water Act and imposed civil penalties for the county’s violations.

Offshore earthquakes, undersea landslides, and tsunamis were among the hazards discussed during a USGS briefing for Congressman Adam Schiff’s staff in Southern California on June 9. Other topics included storms, landslides, wildfires, groundwater, volcanoes, onshore earthquakes,and early warning for debris flows. Geologist Jamie Conrad (Pacific Coastal and Marine Science Center) described USGS studies of the offshore hazards, highlighting recent seafloor mapping off Los Angeles, autonomous underwater vehicle (AUV) and remotely operated vehicle (ROV) surveys done with the Monterey Bay Aquarium Research Institute, and findings offshore the San Onofre Nuclear Generating Station. Congressman Schiff represents California’s 28th district in the Los Angeles area. The day-long briefing was held at the USGS Pasadena Office.

Pollution that stems from actions on land, such as coastal development and agricultural runoff, can harm the health of coral reefs. That’s why the U.S. Coral Reef Task Force (USCRTF), of which the USGS is a co-science lead, established a Watershed Partnership Initiative in 2009. Now the USCRTF Watershed Partnership Initiative has published two new tools to help coastal resource managers reduce the impacts of land-based pollution on coral reefs. The first is a set of indicators and measurements for assessing coral community health, water quality, and sediment. USGS scientists developed the methods for monitoring sediment impacts. The second tool is a checklist to help watershed coordinators implement a successful watershed management plan. Learn more.

USGS researcher Mary McGann (right) instructs students on how to use the microscopes to view the shells of one-celled sea creatures called foraminifera.
A team from the USGS intrigued students at Mountain Elementary School in Soquel, California, with hands-on activities during the school’s April 22 Earth Day Celebration. First through fifth graders looked through microscopes to view the shells of one-celled sea creatures called foraminifera. The shells can tell scientists the age of the sediment in which forams are found, the ocean depths at which they lived, and what the seawater chemistry was like when they built their shells. Many students had never used a microscope and were astonished by the magnified views. The students learned topography by assembling clear plastic trays showing individual contour lines of Angel Island and Monterey Canyon. They also examined the stinky stomach contents regurgitated by albatrosses to see which of the undigested components are natural, like squid beaks, and which are unnatural, like toothbrushes, disposable lighters, and other plastic trash.

In a recent report, the U.S. Geological Survey (USGS) took first place for science research credibility among ocean resource managers and interest group leaders. The study authors asked several hundred people to rank the research reputations of 12 government agencies and organization types on “marine resource management and environmental policy issues.” USGS also took second place overall (behind public research universities) for scientific research credibility. The article, published in Ocean & Coastal Management, analyzed 570 surveys returned by scientists, managers, and interest group leaders. The study also found that the top three indicators of credible scientists were “quality of the methodology used in their scientific research,” “scientific data and information they generate in their research,” and “experience and knowledge of the management of marine resources.” USGS has a long history of high-quality research methods and data sharing, combined with experienced and knowledgeable ocean research staff.

On the morning of May 3, 2016, USGS oceanographer Curt Storlazzi (Pacific Coastal and Marine Science Center) briefed the Department of Defense on coral reefs and climate change in the Pacific Ocean. That afternoon, he briefed the Department of the Interior and its Office of Insular Affairs. Storlazzi leads the USGS Pacific Coral Reefs project. Recent results show that climate change may reduce the ability of coral reefs to protect tropical islands against wave attack, erosion, and salinization of drinking-water resources (read the article). Storlazzi’s briefings described these and other findings, including the likely impacts of sea-level rise and climate change on Pacific atolls that house DoD installations.

Curt Storlazzi free dives to attach a temperature sensor along the reefs in Kauai. USGS wants to understand the local oceanography when investigating why disease has struck Kauai’s corals.
A new video, “Exploring Causes of Coral Disease,” follows USGS researchers as they investigate potential causes of black band disease affecting corals on the Hawaiian island of Kauai. In spring 2015, scientists from the Pacific Coastal and Marine Science Center (Santa Cruz, California) and the St. Petersburg Coastal and Marine Science Center (St. Petersburg, Florida) ran initial surveys to check water temperature, salinity, and whether water running off the land may be affecting coral health. An expanded team will return this summer for more in-depth work. Healthy reefs protect the shore from wave damage, provide shelter for important fish species, and are vital to tourism.

Geophysicist Samuel Johnson checks out the new maps at the USGS Marine Geology Mapping center, Thursday, June 11, 2015, in Santa Cruz, California.
New seafloor maps from Monterey Bay north to Pigeon Point are the subject of a front-page article in the Santa Cruz Sentinel published April 9, 2016. The latest maps released by the California Seafloor Mapping Program reveal complex details of the ocean floor, including new seafloor faults and unexpected patches of bare bedrock. The short faults could be sources of small earthquakes, and the bare patches suggest that the region has less offshore sand than previously thought for replenishing sand eroded from beaches. Read the article, and learn more about the maps in a USGS news release.

Minutes after the 1964 magnitude-9.2 Great Alaska Earthquake (see “The Great Alaska Earthquake and Tsunami of March 27, 1964”), a series of tsunami waves swept through the village of Chenega in Prince William Sound, destroying all but two of the buildings and killing 23 of the 75 inhabitants. Fifty years later, detailed seafloor images revealed the likely cause of the tsunami: a large set of underwater landslides. USGS scientists and their colleagues from Boise State University and the Alaska Department of Fish and Game collected the images while mapping the seafloor in May 2014. Their findings, published in January 2016 in the journal Earth and Planetary Science Letters, underscore the tsunami hazard that submarine landslides can pose in fjords around the world where communities and ports are commonly located.

In September 2015, scientists from the U.S. Geological Survey (USGS) and the University of California, Santa Cruz (UCSC) surveyed rapidly eroding permafrost bluffs on Barter Island, a remnant of low-elevation tundra on Alaska’s Arctic coast. Warming air and sea temperatures in the Arctic are leading to longer periods of permafrost thaw and ice-free conditions during the summer months, which can weaken the coastal bluffs and increase their vulnerability to storm surge and wave impacts. The 2015 survey is part of a long-term effort to document seasonal to decadal coastal-bluff change on the island’s north coast.

Scientists from the Pacific Coastal and Marine Science Center plan to survey the mouth, beach, and nearby seafloor of the Elwha River in Washington, February 15–19, 2016. The survey will continue to document changes triggered by the 2011–2014 removal of two large dams upstream. Scientists on the research vessel Parke Snavely will map the seafloor using swath sonar. Others, on smaller vessels, will map close to shore and about 1 kilometer up the river using echosounders. Scientists onshore will survey the beach using backpack GPS receivers. A crew on the research vessel Frontier will collect sediment samples to measure grain-size. Similar surveys, conducted regularly since 2004, recorded major changes to the area.

Severe coastal bluff erosion, along the southern end of Ocean Beach, San Francisco, California. This storm damage occurred during the 2009-2010 El Niño, which, on average, eroded the shoreline 55 meters that winter. Photo taken on January 20, 2010 by Jeff Hansen, USGS.
Although the U.S. Geological Survey doesn’t directly study or forecast the weather (our sister agency, NOAA, and its National Weather Service do), the USGS studies and documents the effects and impacts of long-term climate changes and weather phenomena across the U.S. and globally. In particular, the USGS monitors streamflow, floods, landslides, erosion, sea-level rise, and many other earth processes that affect communities and that are often affected by El Niño weather patterns. USGS closely monitors these effects to assist the NWS in its responsibilities for hazard warnings and to assist communities across the country in their preparation, response, and recovery activities.

USGS oceanographer Dan Hoover (Pacific Coastal and Marine Science Center) was interviewed by Charles Clifford of KRON4-TV for a story about coastal-cliff erosion that could occur on beaches in and near San Francisco, California, during El Niño storms this winter. Hoover met Clifford on January 12, 2016, at Mussel Rock Park in Daly City. He explained that wave energy typically increases by about 20 percent during an El Niño winter, and storm waves combined with high tides could reach the base of cliffs and cause erosion. He noted that bluffs on different beaches differ in the geology and hydrology that affect how they will fail, making them challenging to study. The interview, broadcast that night, can be viewed at:

Schwartz discussed earthquake probabilities and forecasting and how a large earthquake could impact the state and the central coast. Gee described how the USGS monitors earthquakes in California. The story aired February 7 after the Super Bowl.

New USGS mapping shows that two earthquake faults, the Hayward and Rodgers Creek faults, may be directly connected deep beneath San Pablo Bay, a northern extension of San Francisco Bay, California. Such a connection could increase total fault-rupture length and resultant shaking during an earthquake. USGS research geophysicist Janet Watt, who led the mapping effort, was interviewed by San Francisco Chronicle science editor David Perlman on December 15 at the American Geophysical Union Fall Meeting, where she presented the new findings. Perlman’s article, published December 31st, led to additional interviews of Watt and her colleagues by CBS/KPIX television, KCBS radio, the Marin Independent Journal, KRON-4 television, Talk 910 AM radio, USA Radio Network News, Univision, KTSF Channel 26, the Contra Costa Times, and the San Jose Mercury News.

Stephanie Ross (USGS Pacific Coastal and Marine Science Center and Science Applications for Risk Reduction [SAFRR]) was the USGS coordinator for a National Tsunami Hazard Mitigation Program (NTHMP) workshop, February 1-2, 2016, in Boulder, Colorado. NOAA’s NTHMP provides a customer-based, grass-roots approach to tsunami-hazard assessment and mitigation. The workshop’s goal was to improve collaboration between NTHMP and USGS to provide better tsunami-preparedness products for coastal communities. Topics included: identification and cataloging of tsunami sources (potential earthquakes and landslides); standardized tsunami sources for scenario calculations; and tsunami-vulnerability assessments. About 30 USGS participants and 30 participants from other federal agencies and tsunami-vulnerable states and territories attended the workshop, scheduled just before the NTHMP annual meeting. Stephanie Ross and Nate Wood (USGS Western Geographic Science Center) are the USGS representatives to NTHMP.

On January 21, 2016, USGS research geologist Patrick Barnard discussed initial hazard maps that show potential flooding in the Orange County region from a 100-year storm combined with four scenarios of sea-level rise. The maps are generated by the latest version of the Coastal Storm Modeling System (CoSMoS 3.0), a USGS-led modeling system that projects coastal flooding and erosion due to both sea-level rise and storms driven by climate change. Many California agencies are using CoSMoS data to plan for coastal impacts from El Niño storms. The webinar “Sub-Regional Coastal Storm Modeling Results: Orange County” was broadcast live on January 21 and is now available as an archived recording.
