USGS Releases New Shake Maps

Ad:

The United States Geological Survey has released updated National Seismic Hazard Maps for the United States. From the press release:

Earthquakes remain a serious threat in 46 of the United States. For some areas such as western Oregon and Washington, the new maps contain higher estimates for how hard the ground will shake compared to earlier versions of the maps released in 1996 and 2002.

But for most of the United States, the ground shaking estimates are lower. This revision incorporates new seismic, geologic and geodetic information on earthquake rates and the manner in which the energy released in earthquakes dies off with distance from the rupture.

The USGS National Seismic Hazard Maps can be accessed here.
