The Pacific Northwest Seismograph Network Live in Washington or Oregon? Felt a little rumble recently (like I did)? Want to see if it was an earthquake? You can even check out the live seismographs, including some on Mt. St. Helens.

A world-wide map and chart of recent significant earthquake information is also available at the USGS National Earthquake Information Center.

Forensic seismology and the Comprehensive Test Ban Treaty at Lawrence Livermore Labs. Explosions lack the large, delayed shear waves associated with earthquakes: Indian nuclear test, 1998 (measuring 4.7). A little more on the Indian test and problems with CTBT seismic monitoring at physicsweb.

very helpful real-time earthquake map of SF-bay region (from USGS) that i often run to when wondering if the floor was really moving--or if i was just crazy drunk.

Haven't felt any earthquakes north of Portland at this point. . . but to tangent off for a sec, I've been lately listening to the Portland, OR and SeaTac Air Traffic controllers online, providing some bizarre backdrop to my writing and designing late at night.

Now I know its not really related, but I figured now we're half way to being able to monitor any major disaster in the Pacific Northwest via the web.

There was a "swarm" (over 28 quakes) near San Ramon, CA today... I'm about fifteen miles away, and only felt the largest one (4.2).
