S WAVE STUDIES OF EARTHQUAKES OF THE NORTH PACIFIC PART II: ALEUTIAN ISLANDS,

Abstract

The polarization of the S wave at stations distributed azimuthally about the source is examined for each of 25 Aleutian Island earthquakes. A combination of data from the first motion of P and from the polarization of S is used to study the focal mechanism of the earthquakes. This combination of P and S wave data makes possible a good determination of the focal mechanisms in cases where data from the first motion of P alone do not suffice. (Author)
