TYPE OF FAULT: primarily reverse and thrust, with some right-lateral slip
LENGTH: at least 140 km; complex zone of interlaced and parallel fault segments
NEAREST COMMUNITIES: San Simeon, Cambria, Morro Bay, Surf
LAST MAJOR RUPTURE: November 4, 1927, ML7.3 (?)
MOST RECENT SURFACE RUPTURE: Holocene, in part; otherwise Quaternary
SLIP RATE: unknown
INTERVAL BETWEEN MAJOR RUPTURES: unknown
PROBABLE MAGNITUDES: MW6.5 - 7.5
OTHER NOTES: Faults dip to the northeast. This zone is entirely offshore, with the possible exception of the San Simeon fault, which spans the 18 km between San Simeon and Ragged Point (northwest of the region covered on this map). The earthquake of 1927 is poorly located and may not have occurred on the Hosgri fault zone.
