Earthquake maps on the Web

You can also prowl through earthquake maps using a graphical interface

This is the single document version of the hypertext listing of recent earthquake maps available on the WWW. As the core USGS map engines have improved over time, many of the more unusual US maps have dropped away; some are still on the list but very out-of-date. There is still a lot of flux in the international real-time community. Some maps come online for a few months and then are never updated; others are moved repeatedly within a website. My apologies for not keeping up in these instances; please let me know of broken links or stale maps and I will try and fix the links.
The links below are to the most recent earthquake maps available for the areas indicated. For other seismological information (such as earthquake catalogs) you can start at Steve Malone's Seismosurfing the Internet page. This page usually provides two means of getting the image: as a GIF or JPEG directly (which will spawn an external viewer in some browsers) and as an inline-GIF (which will leave you in your local viewer, usually at the source html page for that map). Some inline maps (usually marked as "with additional info") can get event data if clicked upon. Some links are to dynamic map makers that use resources like the Xerox Parc mapping tools, or the links change with time. Note none of these are locally cached; they are merely pointers directly to the images.

Several sites have several different time windows for their maps (e.g., all historic events) that are not listed; I've tried to limit things to the more recent maps. If you really like a map but want more time, head to the site listed with it and see if there are other time windows (e.g., year-to-date at St. Louis U., past week at USGS Menlo Park).

While the sources for seismic information are generally few (e.g., U.S. Geological Survey's QED locations, Council of National Seismic System's joint and individual network members catalogs), the diversity of effort in making maps from these catalogs provides for entertaining viewing. Some strange artifacts (giant earthquakes in places which didn't have them) can be ferreted out by comparing maps and catalogs; these are produced by occasional system glitches. Maps are both static (generally those marked inline or external) and dynamic (built around specific events or user-input parameters). Generally I have tried to place more primary sources near the top of each regions listing.
