Aerial view of Holocene fault scarp on the Wasatch fault, near American Fork Canyon, Utah The differential motion between the North American, Pacific, and Juan de Fuca plates is causing deformation throughout most of western North America. The majority of this deformation is occurring close to the plate boundaries in California and off the Oregon and Washington coasts, but a significant... 

Reducing Hazards in the Central and Eastern U.S.

Research and products for loss reduction in the Central and Eastern U.S. is accomplished through partnerships among USGS and academic, government, and private partners. USGS staff are located in the Memphis, Tennessee, field office at the Center for Earthquake Research and Information (CERI), in Golden, Colorado, and in Menlo Park, California. The map to the right shows earthquakes (circles)... 

Assessing the Seismic Hazards of Afghanistan

The nation of Afghanistan is gradually recovering and rebuilding from decades of strife, hardship, and isolation from the international community. As the country’s infrastructure is being rebuilt and modernized and as its natural resources are being developed, critical facilities and major construction projects need to be located and designed in such a way as to minimize the potential... 

Landslide Hazards Program

Landslides constitute a major geologic hazard because they are widespread, occur in all 50 states and U.S. territories, and cause $1-2 billion in damages and more than 25 fatalities on average each year. Expansion of urban and recreational developments into hillside areas leads to more people that are threatened by landslides each year. Landslides commonly occur in connection with other major natural... 

Earth Observation essential for geohazard mitigation

12 November 2007 Every year geohazards – such as volcanoes, earthquakes, landslides and tsunamis – claim thousands of lives, devastate homes and destroy livelihoods. In an effort to reduce their impact, more than 250 scientists from around the world gathered for a five-day workshop at ESA’s Earth Observation Centre in Frascati, Italy, to adopt a declaration for an internationally coordinated...
