摘要: [1] We develop an algorithm that automatically detects and characterizes seismic waveforms associated with episodic tremor slip (ETS) events in northern Cascadia. For each hour-long seismogram, the process begins calculation of moving average scintillation index functions. A logic chart is designed to sort observed waveform patterns into a set classes based on these An ETS event always manifest by many station-hours coherent (CT) patterns. Automatic analysis recorded past three years gives results consistent work done tedious visual inspection seismograms. Our algorithm, which free from human oversight, ideal for automatic monitoring system give immediate notice event.
