- Abstract
- We have prepared a catalog of 12,728 earthquakes that have been recorded in Afghanistan and the surrounding vicinity through mid-December 2004. The catalog is compiled from a number of preexisting source catalogs, and it also includes earthquake epicenters and focal-depths that have been computed especially for this project. The catalog includes historically documented earthquakes from before 1900, earthquakes of magnitude 5.5 and larger during 1900-63, and earthquakes of magnitude 4.0 and larger since 1964. The catalog is presented in three formats. One format is a Summary Catalog of Afghanistan Earthquakes which contains only our best estimates of the location and magnitude of each earthquake and which will be the version of the catalog used in almost all applications. A second format is a Master Catalog of Afghanistan Earthquakes which gives the entire range of locations and magnitudes estimated for each earthquake from the preexisting catalogs and which will be of interest primarily to research seismologists. The third format is a Summary of Macroseismic Effects Reported for Afghanistan Earthquakes which provides users with an overview of the effects on humans of past Afghanistan earthquakes, including those that occurred prior to instrumental recording of earthquakes.
