We find that 36 of the 505 fault-plane solutions (M > 3.0, 1981–1990) in southern California have a nodal plane dipping no more than 30&. With the assumption of the low-angle nodal planes being the fault planes, four cross sections are constructed to show the possible horizontal faults in the middle and upper crust. More than half of these low-angle faults are located within or adjacent to the Transverse Ranges. The focal depths vary from 1 km in the southern end of the Sierra Nevada and the… CONTINUE READING
