Debi Kilb and Frank Vernon are monitoring an evolving earthquake swarm that started today south of the Salton Sea. The largest EQ in the swarm, so far, was Mw5.2. Within an hour of the Mw5.2 EQ, an additional ~175 earthquakes occurred. Swarms are common in this region. This 2021 swarm is spatially nestled between the events from 2005 and 2012 —tending more toward the 2005 locations.
