Branch of earth sciences concerned with the study of earthquakes and man-induced seismic waves.
The Hayward fault - Is it due for a repeat of the powerful 1868 earthquake? [ More info] Preparing for earthquakes along this important fault requires studying the history of its movement and its geology, as well as understanding how society has built the area around it.
The Parkfield Experiment - capturing what happens in an earthquake [ More info] Fact sheet describing plans for a San Andreas Fault Observatory at Depth (SAFOD) by drilling into the fault to install instruments for long-term monitoring near the location of the magnitude 6 Parkfield earthquakes.
The San Andreas Fault [ More info] Online booklet on the San Andreas fault system on the California coastal region with discussion of faults, relationship of faults and earthquakes, magnitude of earthquakes, and earthquake probability.
The U.S. Geological Survey Ocean Bottom Seismometer Facility [ More info] The Ocean Bottom Seismometer facility provides technical support for a variety of scientific investigations ranging from deep crustal structure to gas hydrate and surface sediments.
The great 1906 earthquake, 100 years later [ More info] Annotated list of resources about the great earthquake of 1906, which caused significant devastation in and around San Francisco, California, compiled for the 100th anniversary of the disaster.
USGS and the Southern California Integrated GPS Network (SCIGN) [ More info] Field Office involved in operating GPS stations, data recording, and supplying of earthquake data. Links to GPS data analysis, photos, and technical information.
Understanding earthquake hazards in urban areas - Evansville Area Earthquake Hazards Mapping Project [ More info] Evansville, Indiana, is near the Wabash Valley and New Madrid seismic zones and has experienced minor damage from earthquakes in the past 200 years. This fact sheet describes three types of USGS earthquake hazard maps for Evansville and surrounding areas.
United States National Seismic Hazard Maps [ More info] Maps indicating areas where earthquakes may cause damage or disrupt human activities, with information about how those maps are compiled.
United States National Strong-Motion Project (earthquakes) [ More info] National Strong-Motion Program home page with links to program news, recent events, and datasets of digitized accelerograms downloadable as PC (*.zip) and Unix (*.tar.z) files, data processing, stations, research, publications, and personnel.
What is an Ocean Bottom Seismometer? [ More info] Description and uses of the Ocean Bottom Seismometer; a self contained data-acquisition system which free falls to the ocean floor and records seismic data generated by airguns and earthquakes.
