... near a bathymetric high known as Souza Rock and continues southward toward Point Sal with a strike of N25°W. Interpretation of new 2D and 3D seismic‐reflection profile data shows an increase in the length of the originally estimated 23‐km‐long SFZ (mapped between Point Buchon to Point San Luis) to 45...

... mechanisms are consistent with right-lateral strike-slip motion on a vertical fault. A prominent, newly observed feature is an ∼25 km long linear trend of seismicity running just offshore and parallel to the coastline in the region of Point Buchon, informally named the Shoreline fault. This seismicity trend...

INTRODUCTION The geodetic data at Point Arguello, California are insufficient to define the mechanism and location of the 1927 Lompoc earthquake tmagnitude 7.3), but nevertheless those data may be useful in providing constraints upon particular models for that earthquake.
