LARGE-ARRAY SIGNAL AND NOISE ANALYSIS. SHORT-PERIOD SIGNAL WAVEFORM SIMILARITY AT LASA

Abstract

Similarity of signal waveform across the Large Aperture Seismic Array (LASA) was studied. The analysis technique depended on differences in waveform shape but not on amplitude differences. The waveform was found to be very similar both within subarrays and, except for a few cases, between subarrays. Thus, 1-pt (amplitude) equalizations usually is sufficient when processing LASA data both on the subarray and large-array levels.
