June 28th marked the anniversary of three of the largest earthquakes to strike southern California in recent history. It was nine years ago that a magnitude 5.8 earthquake shook the communities along the southern edge of the San Gabriel Mountains. Exactly one year later, southern California was rocked by a magnitude 7.3 earthquake -- the largest in the region in 40 years -- that tore across the Mojave desert and triggered a magnitude 6.4 aftershock beneath the San Bernardino Mountains. Consider this anniversary of the Sierra Madre earthquake of 1991 and the Landers and Big Bear earthquakes of 1992 a chance to reflect upon your level of earthquake preparedness. Have you worked to secure your home or office, in the event that the next big earthquake strikes tomorrow? Do you know what to do during a major tremor to ensure your personal safety? |
