Swarms of shallow (depths < 5 km) LP earthquakes serve as one of the more robust seismic precursors to volcanic eruptions (Chouet, 1996). LP earthquakes also occur at mid- to lower crustal depths beneath young volcanic systems (Hasegawa et al., 1991; Koyanagi et al., 1987; White, 1996). In this paper, we document the occurrence of LP earthquakes at midcrustal focal depths beneath each of the major volcanic centers in northern California that...
