Earthquakes

http://www.eqnet.org
EQNet is a collaborative effort of many of the institutions providing earthquake information in the U.S. It is a free, one-stop source for locating Internet information related to earthquake hazards mitigation.

The U.S. Geological Survey provides much earthquake information via dozens of different Internet avenues (a few of which are listed below). The amount of information is daunting, and, in the past that abundance, along with the multiplicity of USGS sites offering information, has sometimes made it difficult to locate and sort out the information. To remedy that problem, the Survey has launched this Earthquake Hazards Program site - "Earthquake Hazards on the Web" - as an entry point for all USGS earthquake information. It provides information for both global and regional earthquakes and includes sections on earthquake activity past, present, and future; earthquake education for children, grownups, and teachers; earthquake products such as maps, publications, fact sheets, videos, etc.; earthquake research; the USGS Regional Centers and regional Web sites; seismic networks; and frequently asked questions about quakes.

http://www.usgs.gov/themes/earthqk.html
The Survey's "Theme Page" on earthquakes provides information about the many USGS programs and products dealing with seismic hazards as well as a "Hazard-Related Fact Sheet" on earthquakes.

The USGS Regional Centers each offer Web pages on seismic hazards. The Western and Central Regions at the URLs above are good examples. The Western Region Earthquake Hazards Information home page is an excellent place to begin any search for seismic information. It includes pages on the latest seismic events, earthquake hazard preparedness, and all other aspects of earthquakes. It also has an entire section devoted to the 1906 San Francisco earthquake and an extensive annotated list of other Web quake sites.

USGS National Earthquake Information Center
http://wwwneic.cr.usgs.gov
The U.S Geological Survey's (USGS) National Earthquake Information Center Web site comprises pages and pages, maps and maps of seismicity information from around the world. It offers general information about the center and its services, current quake information, general quake information, and access to other earthquake information sources. In addition, users can now search the National Earthquake Information Services historical database to identify historical seismic events (2100 B.C. to the present) for any location, using several user-defined parameters. It also provides a means for users to report a quake, and the "Products and Services" section offers several different earthquake e-mail notification services, several USGS publications on quakes, and numerous NEIC maps portraying local, national, and global seismicity.

http://mae.ce.uiuc.edu
The Mid-America Earthquake (MAE) Center is a multidisciplinary center of expertise whose aim is to reduce losses in future earthquakes that may strike the central and eastern United States. It supports coordinated research programs on essential facilities and transportation networks in order to acquire the data needed to determine possible earthquake hazards and to develop improved strategies for seismic retrofit of constructed facilities. Center research is directed at developing effective and economical mitigation measures considering the unique physical, technical, social, and economic features of the earthquake problem in mid-America. Center programs in education, outreach, and implementation provide the necessary links to extend research results to the public and professional communities.

With PEER and MCEER (described above), the MAE Center is one of three national earthquake engineering research centers established by the National Science Foundation and its partner institutions. The MAE Center consists of a consortium of seven core institutions, and is funded by NSF and each core university as well as through joint collaborative projects with industry and other organizations. Center projects fall under four general types: 1) research, 2) implementation of research results, 3) education and 4) outreach. The center's Web site offers more information about the organization, its goals and intended products, each of its core programs - coordinated research, essential facilities, transportation networks, hazards evaluation, outreach, and education - as well as recent news from the center.

One of the major initiatives of the United Nations International Decade for Natural Disaster Reduction addressed the issue of reducing seismic risk in large cities of the developing world. The RADIUS (Risk Assessment Tools for Diagnosis of Urban Areas Against Seismic Disaster) Project has resulted in much helpful information and some useful tools for evaluating urban earthquake hazards and planning for their mitigation. GeoHazards International, a consulting firm centrally involved in RADIUS, has provided extensive information about the project via its Web site. Included are a description and outline of the project, case studies from around the world, guidelines for developing local RADIUS-type risk management projects, a description of a "Tool for Earthquake Damage Estimation" developed for RADIUS and available on CD, a comparative study of the RADIUS initiative around the world, and a project evaluation. The GeoHazards site itself provides information about subsequent international seismic hazard mitigation efforts, such as the Global Earthquake Safety Initiative.

http://pasadena.wr.usgs.gov/step/
The U.S. Geological Survey has launched this public Web page that shows the probability of earthquake shaking in the next 24 hours in California. These maps graphically illustrate the change in earthquake probability during aftershock and possible foreshock sequences. They are not intended to be used to predict an upcoming earthquake; however, based on previous earthquake sequences, an increase in probability will be seen before about half of California's larger earthquakes. The maps are updated at least once an hour.
