Scientists estimate the probability of a quake with a magnitude of 7.0 or higher on the southern San Andreas fault being triggered is as high as 1 in 100 and as low as 1 in 3,000. Earthquakes along the San Andreas typically occur every 300 years according geophysicists. A hypothetical earthquake of magnitude 8 or greater is expected to produce devastation in urban areas like Palm Springs, Los Angeles and San Francisco. Californians are informing about impending earthquakes through their cellphones, radios and other devices. Gov. Jerry Brown on Thursday signed legislation to develop a statewide warning system. “California is earthquake country,” said Mark Ghilarducci, the director of the state’s Office of Emergency Services. “We must always be prepared and not let our guard down.”On the other side, a guy named Dutchsinse, already a scientist with a different theory of plate tectonic movement, refers to this problem on its channel at Youtube.
