The San Andreas Fault Shows Signs of Awakening

California is used to minor earthquakes. Sitting atop a myriad of fault lines, both minor and major, earthquakes are away of life. Most of them are un-noticed as they are too small to feel. But over the last ten days, California has had a series of quakes of magnitude 3.0 or above on the Richter scale.
The LA Times records three such incidents. Another has been reported by the USGS today.
California sits in an area that is geologically very active. Plate margins grind against each other causing the tremors. The San Andreas Fault is a huge gash in the landscape that runs from Cape Mendocino down to the Mexican border. It’s a transform, or slide fault. The leading edge of the North American Plate and the Pacific plate slide past each other. They move in small fits and starts but on occasion get stuck. The pressure builds and builds, until whatever prominence of rock holding them in position gives way, and the plates move causing an earthquake.
