Central & Southern California
Notes
This morning at about 8:20 A.M. in 1857 a massive earthquake rocked Central and Southern California as a result of the San Andreas Fault Zone rupturing unilaterally from Parkfield in Monterey County all the way down to the Cajon Pass in San Bernardino County. Although this event was not instrumentally-recorded it can be safely extrapolated from the length of the 220 to 250 miles fault rupture with a maximum 30 foot or greater horizontal displacement that it was about a M8.0 earthquake. A woman was killed by falling rubble near Fort Tejon in what is now southern Kern County and one man may have died of a heart attack in Los Angeles. Mission San Buenaventura was heavily damaged. Rivers from the Los Angeles Basin to the Mother Lode were temporarily thrown out of their banks or reversed course. Now-dry Tulare Lake in the western San Joaquin Valley experienced a tremendous seismic seiche that caused water to slosh for miles outside its banks stranding fish. There were numerous changes in wells and springs in many areas. The night before the earthquake the Santa Barbara area experienced some sharp jolts that may have been caused by regional stresses related to the impending great quake although that area is not particularly close to the area of the epicenter. There may have been some sympathetic rupture on a fault adjacent to the SAFZ in what is now southwestern Kern Co. If an event similar to this one were to occur today the damage and casualties would be appalling and it would supplant the 1906 San Francisco Earthquake and Fire as the worst disaster in California history.
