"SANTA ANA, Calif. -- Southern California residents should remain on heightened alert until Tuesday for the increased possibility of a major earthquake, officials said.

The warning by the Governor's Office of Emergency Services follows a series of small temblors deep under the Salton Sea, which is located on the 800-mile-long San Andreas fault, the Orange County Register reported Saturday.

Such warnings are typically issued once or twice a year, said Kelly Huston, the deputy director of crisis communications for the Governor's Office of Emergency Services."
