George and I are big geology geeks, so living in California gives us a chance to see some of the most interesting geology on the planet. This website serves as a place where you can see the many sites we have visited along the San Andreas Fault, the greatest fault line on Earth!

A Little Bit About the San Andreas...
The San Andreas Fault is a strike-slip fault that stretches for 800 miles from Point Arena in Northern California to the Salton Sea in Southern California. Named after a lake in the San Francisco Bay Area, it's the boundary between two of the Earth's massive continental plates: the Pacific Plate and the North American Plate. Since records began in North America, about 13 major quakes have occurred along the San Andreas, such as the Fort Tejon Earthquake of 1857, the Great San Francisco Earthquake of 1906 and the Loma Prieta Earthquake of 1989. It's only a matter of time when the next "Big One" will strike!

Measuring Seismic Activity
George started a project in 2010 where built his own electronic seismometer/seismograph. Learn more about George's project here.

In March of 2011, the USGS selected our house to participate in their NetQuakes program. The NetQuakes seismograph accesses the internet via a wireless router connected to our existing broadband internet connection. The seismograph transmits data only after earthquakes greater than magnitude 3 and otherwise do not consume significant bandwidth. To learn more about the program, click here.
