... and suggests that, under ideal conditions, offshore events can be located to within 1 to 2 km of their true locations. Our final locations for most clusters are well correlated with known local tectonic features. We relate the 1981 Santa Barbara Island ( M L = 5.3) earthquake with the Santa Cruz fault, the 13...

... of this earthquake (Lee et al., 1978) used a modification of this model that subdivided the upper two layers into seven layers to better approximate the velocity profile in the Santa Barbara Channel. Wallace et al. (1981) derived a velocity structure by inversion of the strong-motion records generated...

... the Santa Monica Mountains through the southern Santa Barbara Channel. The north-dipping backlimb of this anticline is 20–30 km wide and 220 km long; its presence suggests a very large north-dipping thrust that could generate very large earthquakes. The slip rate for this fault, however, is substantially...

... at depth along the rupture surface (Hauksson and Gross 1991). No tsunami has yet been directly related to the event (Lander et al. 1993). This event is suggestive of the potential for strong earthquakes in the nearshore region. THE 1981 SANTA BARBARA ISLAND AND 1986 OCEANSIDE EARTHQUAKES The Catalina Fault...

... the overall trends in deformation are well defined, it is poorly understood which faults and associated folds accommodate this shortening, in part, because GPS station coverage is generally limited to the mainland and Channel Islands. Several small‐to‐moderate size earthquakes have occurred in the Santa...

.... There are records of a few historical tsunamis in the Santa Barbara Channel (e.g., Toppozada et al., 1981 ; Borrero et al., 2002 ). Most notably, runup from the 1812 earthquake (see preceding) is thought to have reached as high as 4 m at Refugio Beach and 2 m in Santa Barbara ( Fig. 2 ). Models in Greene et al...

... Santa Barbara earthquake ( Corbett and Johnson, 1982 ). The parameters we used for the final model are: For the San Cayetano fault, we used a propagation to slip ratio of 1, we used 20 Trishear zones, and we did not apply an offset for the Trishear angle. For the Red Mountain/South Sulphur Mountain...

Analysis of damage to these missions, as well as earthquake damage on 21 December to the missions in Santa Barbara County, is based on the original 1812 mission documents studied and quoted by Toppozada et al.
