Toppozada and others in 1981 proposed a location 10–20 km (6.2–12.4 mi) southwest of the 1925 Santa Barbara earthquake. Details of a possible tsunami would suggest a thrust-mechanism for the earthquake; similar to the 1978 Santa Barbara earthquake (>M5) which had a left-lateral and north-dipping thrust mechanism. [6]
California Geological Survey researchers have reported that the fault is capable of an 8.0 earthquake, along with tsunami affecting Santa Barbara, Ventura, and Santa Monica. [3] A big earthquake on the fault estimated to occur every 400 to 2,400 years, the last being about 800 years ago.
The California Geological Survey releases tsunami hazard maps for Ventura, San Diego, Marin, Napa, Santa Cruz, Solano and Sonoma counties to help residents understand risks.

It generated a 3.4-meter tsunami around the Santa Barbara coast. The damage from that was moderate and significantly less deadly. That quake may have been triggered by the Wrightwood earthquake however, the location of its epicenter remains uncertain. [14]
The 1927 Lompoc earthquake occurred on November 4 at 05:49 PST with an epicenter off the coast of Santa Barbara County Southern California. [1] The earthquake measured 7.0 on the moment magnitude scale and had a maximum Modified Mercalli intensity of IX (Violent). It caused widespread damage in several towns of Santa Barbara County.
