A magnitude 3.2 earthquake struck Lamont, California, east of the San Andreas Fault. The earthquake’s depth was relatively shallow at 12 km. Today’s earthquake would have been the first powerful earthquake (over magnitude 2.5) in over a month.
The San Andreas Fault is known as a strike-slip fault. It falls along a boundary where two tectonic plates slide against each other in opposite directions. The American Plate slides Southward, and the Pacific Plate slides Northward. The Pacific Plate slides at a much faster rate than the American Plate. Seismic activity is usually more active on the Pacific Plate side of the fault line. California has nearly a hundred earthquakes daily – most are microquakes and not felt unless the person feeling it is directly over the epicenter.
The earthquakes mentioned here today have been documented by USGS, and verified by CalTech, EarthquakeTrack, Pacific Northwest Seismic Network, and other contributors within California’s extensive seismic research programs – all credible and globally recognized seismic activity monitoring systems. UTC is an abbreviation for Coordinated Universal Time. Anyone with the MyShake App was alerted for the following quakes. There is no need to panic since seismic activity along the San Andreas Fault Line is normal.
