| Abstract: | Summary The focal mechanisms of two Peruvian earthquakes, January 15, 1958, and January 13, 1960, are determined using data from both the first motion ofP and the polarization ofS. The fault motions correspond to strike slip motion on neighboring faults corresponding in strike to geophysical evidences of regional faulting. The motion is left lateral in one of the shocks, right lateral in the other. |
