摘要:
Earthquake focal mechanisms present information on fault plane and stress direction, which is crucial for understanding tectonics and seismicity. Source focal mechanisms of small earthquakes are often difficult to determine from waveform modeling but feasible to infer from initial polarities. Here, we employ a state-of-the-art neural network infused with an attention mechanism to simultaneously pick arrivals and determine the first-motion polarity. The model is trained and tested with data from southern California. Compared with polarity inference with manual picks in the catalog, predicted po
