Researchers have developed EQNet2, a new Transformer-based model designed for earthquake monitoring. This model processes data from multiple seismic stations simultaneously, unlike previous methods that analyzed stations independently. EQNet2 jointly predicts phase arrivals, polarities, source location, magnitude, and event association, leading to more complete and reliable earthquake catalogs. Testing on data from Northern California and the Ridgecrest and San Francisco Bay Area demonstrated EQNet2's ability to detect weaker arrivals, reduce false positives, and improve event association.
