1857. Sacramento to Fort Tejón, San Bernardino and Fort Yuma. At Fort Tejón 'a fissure 20 feet wide and 40 miles long: the sides came together with such violence as to make a ridge ten feet wide and several feet high.' Fissures at San Bernardino.
1865. This was a smart shock from San Francisco to San José, apparently along the line of the Portolá fault. The severity of this earthquake, as suggested above, may have mitigated the local severity of the earthquake of 1868, which was in the same rift, but not so severe in this part of it.
1867. This was violent disturbance about Klamath Lake. A great crack said to have opened in Siskiyou County, but the locality is not recorded.
1868. A very severe earthquake, there being a rift on the east side of the bay, as also at Olema, in the Santa Cruz Mountains and for over a hundred miles from Cholame through the Carisa Plain.
1872. Owens River, Inyo County. Fissure at Big Pine 50 to 200 feet wide, 20 feet deep, extending 50 miles or more. Numerous shocks, very violent, these preceded by weaker shocks for a year or more.
1890. Mono Lake, similar disturbances.
1892. Vacaville, Winters, etc., extensive local disturbances, the fissures not traced, but said to have been along Bio de los Putos on the west side of the valley of Solano and Yolo.
1897. San Jacinto Valley, with a notable fissure, the details not at hand.To these might be added the vigorous single jolt of 1893 in the San Fernando Mountains, which did little harm because occurring in an uninhabited region. The writer was at Saugus at the time, and noted the fall of trees and the flinging of rocks down the mountainside. There seems to have been but a single wave, which would have done great injury in a populous district. It came from a short fissure in Pico Cañon.
Since the earthquake of 1906 many small earthquake waves have followed, evidently harmless details in the process of adjustment. Looking over Holden's record, we see that many small disturbances have taken place along the line of the great fault in question, besides the great earthquakes of 1868 and 1906 and the lesser ones of 1800, 1818, 1836, 1839, 1865 and 1868.
In 1808 there were twenty-one shocks at the Presidio of San Francisco. In 1812 the shocks caused a tidal wave in the bay extending up to the plaza. In 1813 or 1815 'all the buildings' in Santa Clara Valley were shaken down. There were not many and all these were of adobe or sun-dried brick. In 1851, a sharp shock in San Francisco. In 1852, a shock at San Francisco, with a fissure on the San Bruno fault, through which Lake Merced drained into the sea.
1856. Severe shocks at San Francisco, the water in the bay sank two feet.
1863, 1864. A sharp shock at San Juan Bautista.
1890. Sharp shock along Portolá fault. The Pájaro bridge had a pier shifted 18 inches, as in 1906. The same crack opened at Chittenden, and the main arch in the Mission Church at San Juan Bautisia was injured. A rift opened in the soil from Chittenden to San Juan as in 1906.
