Genetic time delay estimation for earthquakes detection and measurement

摘要

The problem considered here relates to locating the seismic focus, and so the epicentre of an earthquake, or earth tremor, as well as to general studies on propagation of the s hock waves in different cases. The key concept is in estimating the time delay between waveforms detected at different points of earth's surface, and coming from one source. A technique emplying genetic algorithm and incorporating a digital filter with fractional delay is presented. When compared with traditional approaches, it proves more reliable and more precise.
