Description
Seismic signal detection and phase arrival picking had been initially carried out manually by qualified analysts. Currently, the introduction of large digital seismic monitoring networks has led to the necessity of automatic detection and picking tasks. The latter are extremely important, not only because an earthquake or a nuclear explosion must be detected and located automatically, but also to optimize the necessary storage memory. Moreover, an automatic picking task can considerably reduce the analyst effort and make picking faster and more objective. The need for automatic seismic signal detection and picking algorithms has lead many researchers to investigate various techniques, ranging from simple to sophisticated procedures. Each procedure has advantages and disadvantages. The choice of an appropriate algorithm depends on the performance required and the type of the expected signal (repeating sources, low/high SNR, emergent, impulsive). The aim of this study is to discuss the most popular and frequently employed automatic detection and picking algorithms.
