Quakes throughout the risk vectors and a 7.9 quake in Tonga yield the following NERVS update:
4.5 or greater magnitude quake in next 10 days:
- Primary vector: Northern California (including offshore), Oregon, Washington, Southern California (including offshore, Baja and Gulf of California), Central California
- Secondary vector: Central Alaska, Vancouver Island, Italy, Iran, Sunda Strait
- Also possible: China, Japan, Taiwan
NERVS Accuracy Check
Last round included several quakes that occurred within the risk vectors and time envelope, though the most dramatic SF area quake fell short in magnitude (3.5). More detailed accuracy check with be completed at another time.

For those new to the list, NERVS stands for:
Numerical (or "non-scientific")
Earthquake
Risk
Vector
System
...and is based on prior California quakes being preceded by similar patterns of quakes in other areas.

Hey. Whoah. An SF earthquakes service is available on Twitter. Thanks to NERVS member Dan for the resource. http://twitter.com/sfearthquakes
And if Google is more your style, here's a new way to search for quakes. Thanks to NERVS member Mark for the resource. http://googleblog.blogspot.com/2009/03/shaking-up-earthquake-searches.html
If you live in the Bay Area, don't miss the USGS simulation of a 6.8, 7.0 or 7.2 quake on the Hayward and Rodgers Creek faults.
When you get to the page, click on the images to yield the animated versions. Also available in HD.

When is an uplifting experience a bad thing? When it's caused by bulging magma in the United States' largest volcano. If your travel plans are taking you to Yellowstone in the near future, first check the Yellowstone Volcano Observatory alerts and updates:
Just how large is the Yellowstone caldera? View the Google map provided by NERVS list member Caleb Tonn:
