Seismic swarm

A high-frequency seismic swarm began at the volcano on 4 June, peaking on 10-11 June, and centered along a roughly NE-SW zone 20 km long (figure 1). Of the numerous earthquakes recorded by the regional seismic network (most stations are E or S of the island), 12 were locatable. These events were concentrated at ~8 km depth (1-65 km depth range) and had magnitudes between 2.9 and 4.4 (the largest, at 27 km depth, was recorded at 0148 on 11 June). Several earthquakes were felt by island residents, but there were no reports of damage or injuries. On 13 June, a portable 3-component seismograph was installed on the island, previously uninstrumented, to supplement the regional seismic network, but activity declined, and only two additional events had been located as of 16 June.
