Abstract
Even if you have been vacationing on some far off, uninhabited island, you must have heard by now that southern California is still being rattled by aftershocks from recent magnitude 7.4 and 6.5 earthquakes. In the few weeks since those quakes, more than 5,000 aftershocks have been recorded. California has endured nine magnitude 6 and 7 earthquakes in the last five years. Considering the increasing proximity of these quakes to the San Andreas fault, everyone here has become (understandably) more concerned about earth movements.
