Although they mostly go unnoticed by humans, small earthquakes occur much more frequently than large earthquakes, and knowing ...

USGSA new earthquake hazard map by the U.S. Geological Survey for Oregon and Washington, illustrating the risk that ground shaking will exceed certain thresholds during a 50-year period. Brown is ...

New USGS government maps extend earthquake hazard zones nationwide, including some surprising states. The 5.8 magnitude earthquake that struck Virginia on August 24, 2011, damaged monuments like ...

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 hazard map also shows a heightened risk of quake damage around New Madrid, Mo., which has long been seen as a seismic hot spot. That region has experienced a higher rate of natural quakes in ...

This assessment revealed that hazard maps for the U.S. (California), Japan, Italy, Nepal and France seemed to overpredict earthquake damage.

A new federal map released Monday shows parts of Oklahoma are now as seismic as parts of California and Alaska, long the nation’s leaders in earthquakes, and for the first time includes man-made ...

A new study by Northwestern University researchers and coworkers explains a puzzling problem with maps of future earthquake shaking used to design earthquake-resistant buildings. The research was ...
