Abstract

Station corrections have been established for the long period, vertical component P wave amplitudes for the center of each subarray of the D and F rings at LASA. Data from 56 events have been analyzed. The results suggest that amplitudes recorded at stations Fl and F4 are above average, whereas the amplitudes at stations F2 and D1 are less than the average. There appears to be little dependence on azimuth or the source region. The amplitude variations of long period P waves over LASA are much smaller than those reported by Broone, et al., (1967) for short period P waves.
