Abstract
A method of predicting impending coastal seismic activity by using ocean-based acoustic sensors. Acoustic sensors are used to sense and record low frequency acoustic events, including primary and tertiary waves. Characteristics that may be sensed and recorded include frequency, amplitude, and duration of the acoustic events. More specifically, the occurrence of T-waves over a selected time period are sensed and recorded. A decrease in the rate of the occurrence of T-waves during a portion of the selected time period is an indication of impending seismic activity.
