For scientists aboard the Escanaba Trough expedition, obtaining sediment cores or deep-sea biological and geological samples after a Jason dive is only the beginning.

Embarking on a three-week deep-sea research expedition requires a lot of preparation. For this expedition to Escanaba Trough, U.S. Geological Survey scientists and partners spend the first few days in port, building their laboratory space aboard the research vessel Thomas G. Thompson.

During September 2017, Hurricane Maria triggered >70,000 slope failures throughout the mountainous regions of Puerto Rico (USA). Since then, the USGS has had a multi-faceted team working to understand landslide hazards in Puerto Rico.

Building and maintaining a landslide hazards program as a state agency presents many opportunities and challenges.

A Burning Question: What can long-term datasets tech us?

Large lahars (volcanic mudflows) pose substantial threats to people and property downstream from Mount Rainier, Washington. Lahars can occur during an eruption, as happened at Mount St. Helens on May 18, 1980. Lahars can also begin as large landslides that occur without warning, traveling down river channels to densely populated areas downstream.
