Deep Learning for Picking Seismic Arrival Times
Abstract
Arrival times of seismic phases contribute substantially to the study of the inner working of the Earth. Despite great advances in seismic data collection, the usage of seismic arrival times is still insufficient because of the overload manual picking tasks for human experts. In this work we employ a deep‐learning method (PickNet) to automatically pick much more P and S wave arrival times of local earthquakes with a picking accuracy close to that by human experts, which can be used directly to determine seismic tomography. A large number of high‐quality seismic arrival times obtained with the deep‐learning model may contribute greatly to improve our understanding of the Earth's interior structure.
