The U.S. Geological Survey released new earthquake hazard maps for the nation on Thursday, expanding seismic risk areas along the East Coast and in California, among other areas. The maps and ...

2014 USGS National Seismic Hazard Map, displaying intensity of potential ground shaking from an earthquake in 50 years (which is the typical lifetime of a building). To help make the best decisions to ...

USGS said it typically updates the national seismic hazard models and maps every six years, in sync with building code updates. Updates include data on earthquake frequency and intensity, among ...

The U.S. Geological Service recently released an update of U.S. National Seismic Hazard Maps that reflect the latest analysis of where future earthquakes will occur, how frequently they may occur, and ...

The U.S. Geological Survey released new earthquake hazard maps for the nation on Thursday, boosting the risk of seismic damage in the South and East Bay — especially for tall buildings.

The new hazard model estimates where, how often and how strongly earthquake ground shaking could occur in the United States during calendar year 2016.

The recent magnitude-5.2 earthquake in southern Illinois is a reminder that earthquakes are a national hazard. Today, scientists at the U.S. Geological Survey (USGS) are revealing how shaky the ...

USGS Updates Seismic Hazard Maps, Ground Shaking Estimates May 01, 2008 Last week's magnitude-5.2 earthquake in southern Illinois is a reminder that earthquakes are a national hazard, says the U.S ...

“By including human-induced events, our assessment of earthquake hazards has significantly increased,” in some states, Mark Petersen, USGS national seismic hazard mapping project chief, said ...

Previously, USGS maps only showed natural earthquake hazards. But concerns over potential damage from induced earthquakes prompted USGS to update its 2014 hazards map to show induced and natural ...

The USGS periodically releases seismic hazard maps to show the chance of major shaking from tectonic earthquakes over a 50-year period---the average lifespan of a building. These probabilities are ...
