During the March 21, 2024 lahar evacuation drills, thousands of students walked to the Washington State Fairgrounds in Puyallup, Washington to practice evacuating from a lahar generated by Mount Rainier. A lahar, or volcanic mudflow, could reach this area in about 3 hours.

USGS installed an array of seismometers in a field in Gaziantep, Turkiye in order to record ambient noise and earthquakes, including the aftershocks of the devastating earthquakes of 2023. Robert Sickler of the USGS in the foreground and an AFAD employee in the background.

NATIONAL SEISMIC HAZARD MODEL

The National Seismic Hazard Model stands as a testament to scientific innovation in the service of public safety. This congressionally requested update provides an essential tool to many stakeholders by showing where large earthquakes are most likely to occur, allowing for better mitigation and preparedness in those areas.

Annual number of earthquakes with a magnitude of 3.0 or larger in the central and eastern United States, 1973–2024. The long-term rate of approximately 25 earthquakes per year increased sharply starting around 2009.

Scientists at the USGS are installing sensors in Wellfleet MA, part of the Cape Cod National Seashore to evaluate the long-term and short-term chemical and geomorphic changes within wetlands. 

As sea-level rise accelerates, vegetation transitions are increasingly observed and USGS scientists are busy assessing those changes. Shoreline at the Cape Cod National Seashore in Wellfleet, MA.
