The best kind of earthquake is distant, deep and relieves stress upon those faults that threaten populated areas, while reminding folks that preparedness is all that is required. This series of quakes is just what the doctor ordered. The Gorda Plate is breaking up as it disappears under North America while being squeezed NNW by the Pacific Plates march to Alaska. This earthquake occurred on an unmapped fault in an area that is rather over-mapped for faults. I predict this fault will be the next Napa Valley (about 25 million years from now). :) *** We get our complimentary LED flashlight every time were near a Harbour Freight store and have them hanging in every room. Sturdy shoes by the bed. A weeks worth of drinking water. Everyone in the household knows how to turn off the gas main and to protect oneself from flying glass and stuff falling on your head. Humboldts Big One will drown a lot of people and cause a bothersome nuclear radiation event. Fort Braggs Big One, while serious, will be dwarfed by the chaos south. Fort Bragg is at the south edge of the triangle seismologists call the Slabless Window; a little chunk of crust in an eddy between the North American Plate and the Mendocino Triple Junction. It is so stable it is considered the premiere location to study marine terraces of ancient sea levels. The Pygmy Forest is a geologic formation, but not a seismic one! The one caveat is that Franklin and Main is probably a parallel fault to the San Andreas Fault offshore. See how the Noyo River and Pudding Creek have identical right-slip offsets? The story goes is that Franklin Street between Redwood and Oak swam like the Loch Ness monster during the 1906 event. Eventually, well know if its true.
