USGS science at AGU
Tsunamis, climate change, Hawaiian volcanoes, planetary science, water, minerals, and more
Released: 12/2/2011 11:00:00 AM
SAN FRANCISCO — From nearly 900 abstracts by USGS presenters at this year's American Geophysical Union conference, we've selected some of the newest, most exciting topics that USGS scientists will explore at AGU. Tips are presented in topic areas, chronologically with room numbers, session numbers and a summary.
The AGU conference is held Dec. 5-9 at the Moscone (West and South) Convention Center in San Francisco.
Monday, 12/5, 1:40 p.m., MS Halls A-C
Estimating the likelihood of extreme seismogenic tsunamis
USGS Scientist: Geist
Because the likelihood of tsunamis caused by earthquakes is directly linked to the size of the generating earthquakes, we can determine the likelihood of a tsunami occurring in a certain location by looking at earthquake data. Because of complicated wave evolution near shore, estimates for extreme tsunamis are site-specific.

Field observations of tsunami characteristics after 2011 Japanese tsunami
USGS Scientist: Richmond
NH13G-07 /Oral presentation
Characteristics of the Tohoku tsunami deposits reveal information on the geologic processes of the destructive waves as well as criteria to identify paleotsunami deposits in the geologic record. The international team observed height and direction of tsunami flow, mapped erosion features and assessed and sampled sediment deposition in shallow trenches.

Assessing tsunami hazard from the geologic record
USGS Scientist: Jaffe
Hazard assessments have begun to incorporate tsunami deposits into the few available historical records of tsunamis, a technique that is growing more accurate as scientists are able to distinguish storm deposits from tsunami deposits. However, studies of the 2011 Japan tsunami suggest that deposits may not be an accurate measurement of inundation distance, and that other proxies such as geochemical signatures and approaches such as sediment transport modeling are needed.

Marine ferromanganese deposits as a source of rare metals for high- and green-tech applications: Comparison with land-based deposits
USGS Scientist: Hein
Deep-ocean deposits of rare earth minerals may offer a potential solution to global demand.
