Chapter 11: Earthquakes

Further Study

Locating an epicenter (Copyright © Tasa Graphic Arts, Inc.)We have made a concerted effort to search the Web for relevant material, but no matter how hard we try, there will always be more information available than we can possibly examine.

However, the following list contains links to many of the most interesting and informative Web sites related to topics explored in the chapter that we were able to locate. Check them out, but make sure you come back to do more investigating when you're done.

Global Seismic Hazard Assessment Program

In order to mitigate the risk associated with the recurrence of earthquakes, the GSHAP promotes a regionally coordinated, homogeneous approach to seismic hazard evaluation. The ultimate benefits are improved national and regional assessments of seismic hazards, to be used by national decision makers and engineers for land use planning and improved building design and construction.

The site includes a great map showing global seismic hazards.

IRIS Consortium

The Incorporated Research Institutions for Seismology (IRIS) is a consortium of United States Universities that have research programs in seismology. The purpose of IRIS is to develop and operate the infrastructure needed for the acquisition and distribution of high quality seismic data.
Modified Mercalli Intensity Scale (USGS)

The modified Mercalli intensity scale can be found here.
National Earthquake Information Center (USGS)

The National Earthquake Information Center (NEIC), a part of the Department of the Interior, U.S. Geological Survey, has three main missions. First, the NEIC determines, as rapidly and as accurately as possible, the location and size of all destructive earthquakes that occur worldwide. Second, the NEIC collects and provides to scientists and to the public an extensive seismic database that serves as a solid foundation for scientific research, principally through the operation of modern digital national and global seismograph networks and through cooperative international agreements. The NEIC is the national data center and archive for earthquake information. Third, the NEIC pursues an active research program to improve its ability to locate earthquakes and to understand the earthquake mechanism.
