Maui is located 15 km (9 mi) east of Molokaʻi and 15 km northwest of Lānaʻi. Known as the Valley Isle, it encompasses 1883 sq km (727 sq mi), making it the second largest of the main eight Hawaiian Islands. A fringing reef surrounds much of the island. However much of the live coral growth can only be found on the leeward west coast where the reef is protected from waves by the surrounding islands. Reef growth is limited on the windward northeast coast due to wave impacts.

The USGS has conducted a number of studies along the west coast of Maui including seismic studies, video mapping, coastal circulation and sediment dynamics. Click on any of the following links for more information.
