The M7.8 Nepal Earthquake, 2015 – A Small Push to Mt. Everest
In the days and months following the 2015 earthquake, scientists spread out over the area and collected as much data as they could, while also being sensitive to the humanitarian crisis and assisting with immediate hazard assessments. This is a summary of what happened, the data that scientists have been able to gather, and how the data has helped them to figure out the underlying science of this event.
M6 South Napa, California Earthquake – August 24, 2014: What We Know After One Year
In the wee hours of Sunday morning at 3:20am, the residents and wineries of Napa Valley were shaken by a magnitude 6.0 earthquake, the largest in the San Francisco Bay Area in over 25 years, and the first since the M7.9 1906 earthquake to rupture on the surface. This article describes what USGS (and USGS-funded) scientists have learned from the data one year after the earthquake.
The "Snow Plow Theory"* of Early-Arriving Tsunamis
During the M9.2 Alaska earthquake in 1964, a large tsunami locally impacted the coastal town of Seward only 1.5-2 minutes after the start of shaking, and then 30 minutes after the earthquake another large tsunami inundated Seward and many other towns along the coast of Prince William Sound. Yet another tsunami later moved out across the ocean to affect distant coastlines as well. Sudden displacement of the seafloor must have occurred somewhere close to shore, but where and why?
