At 4:57 a.m. local time ( 11:57 UTC ) on June 28 , 1992 , a magnitude 7.3 earthquake awoke much of Southern California . Though it turned out it was not the so-called " Big One " as many people would think , it was still a very strong earthquake . The shaking lasted for two to three minutes . Although this earthquake was much more powerful than the 1994 Northridge earthquake , the damage and loss of life were minimized by its location in the sparsely-populated Mojave Desert
