Additional documentation is available on this catalog. Times of events may not match those found in other catalogs, however, since care was not taken to check the times. About 10% of the events in this catalog were listed in local time, while the remainder were listed in GMT. We have tried to locate and correct these times, however, care should be used here. Further documentation is available on the Pacheco-Sykes catalog. in the file pachsyke.doc in this directory. 1. VARIABLE NAME HISTOGRAM NAME 2.

If you use, need, produce, handle, archive, or are concerned with or about earth-science data sets, your participation in the EDBS is solicited. Please note that government regulations require prepayment on all orders. Telephone requests will be accepted, but data cannot be shipped until payment is received. The EARTHQUAKE DATA BASE SYSTEM consists of three data bases; this section of the documentation presents information for the Multi-Catalog Historical Earthquake Data Base. For more information about the US or INT Data Bases, contact Glen Reagor (address and telephone number is at the top of this page). ======================================================== ======================================================== END OF DOCUMENTATION FILE ======================================================== ======================================================== +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ NOTE: This is a partial documentation of the USGS format The full format can be seen in the file: /data/usgs/gsform.txt or as a series of *.pcx files in the directory: /data/usgs on the North American CD-ROM or on the Global Catalog CD-ROM. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ END OF DOCUMENT FILE =============================================================
