Historic Earthquake Catalog for Cascadia - 1793-1929

The Cascadia Catalog covers Washington, Oregon and British Columbia. It is based on a compilation of verbatim accounts from a dozen earlier earthquake catalogs (covering a variety of geographic areas and time ranges), with the addition of newspaper articles, weather observers' reports, diary entries, and other pieces of information about historic earthquakes in Washington, Oregon, and British Columbia between the years of 1793 and 1929. In addition to event summaries, the verbatim text of the original sources is available. Of the 677 events cataloged, over 100 are previously uncataloged. Over 400 information sources, in addition to the dozen catalogs included, have been incorporated into this catalog.
