The Midwest was recently rocked with tornadoes, and now the west has been shaken with earthquakes. Back-to-back earthquakes hit the San Francisco bay area on Monday morning. It appears at this point that no damage or injury has occurred.
The United States Geological Survey reported the first temblor with a magnitude of 2.9 and the second one at 4.0. The San Francisco earthquake was felt within a 60-mile radius but police received no reports of injury.
Seismologists reported that the quake occurred on the Hayward Fault that runs along the San Francisco Bay. The U.S. Geological Survey reports that the Hayward Fault has the highest chance-1 in 3- if producing an earthquake of a magnitude 6.7 or higher in the Bay Area within the next 30 years. There is a 62 percent chance that the Bay Area will see a larger quake than the two on Monday by 2032.
The Hayward fault runs along the densely populated Bay Area and is part of a greater San Andreas Fault System. Major cities along this system include Oakland, San Leandro, Hayward, Fremont, Richmond, El Cerrito, Berkeley, and San Jose.
The Hayward Fault was rocked with an earthquake in 1868 that registered at 7 on the richer scale. Scientists say that the large earthquakes seem to have a 160-year interval on the Hayward Fault. This evidence would back the above projections that the “big quake” is on its way in the near future.
Seismologist David Schwartz reported on KGO-TV, "These earthquakes, these 4's, are just an indication of ongoing activity, ongoing stress on the fault. They do nothing to relieve the likelihood of something larger happening.”
