Due to a lapse in appropriations, the majority of USGS websites may not be up to date and may not reflect current conditions. Websites displaying real-time data, such as Earthquake and Water and information needed for public health and safety will be updated with limited support. Additionally, USGS will not be able to respond to inquiries until appropriations are enacted. For more information, please see www.doi.gov/shutdown
Science for a Risky World: A USGS Plan for Risk Research and Applications – USGS publishes strategic plan for examining risk
USGS explores opportunities to advance its capabilities in risk assessment, mitigation, and communication in new strategic plan.
Learn About USGS Hazards Science and More About National Preparedness Month: The very nature of natural hazards means that they have the potential to impact a majority of Americans every year. USGS science provides part of the foundation for emergency preparedness whenever and wherever disaster strikes.
"In Yosemite Valley, rockfalls can happen every four to five days, where boulders that can be larger than your average car or apartment building thunder down steep mountainsides." - Seeker
Better performance and new features: landslides and liquefaction estimates, population map layer, Spanish Did You Feel It?, and aftershock forecasts.
A model developed by researchers at Indiana University and the USGS can help experts address such risks by estimating the likelihood of landslides that will be caused by earthquakes anywhere in the world within minutes. Read story.
USGS scientists have been developing a system to quickly identify areas where landslides may have been triggered by a significant earthquake.
We usually hear about landslides and avalanches that are caused by large amounts of rainfall, the shaking from earthquakes, or a volcanic eruption, but we may be hearing more about avalanches caused by the (seemingly innocuous) melting of ice in the coming years.
The deadliest individual landslides in the U.S. recently were in places where there had previously been a landslide. Why do landslides happen in the same place instead of on nearby slopes that appear to be just as likely, if not more likely, to slide?
