Sabancaya volcano (Peru): strong seismic swarm

Seismic recording from late on 18 July (SAB station, IGP)
Seismic recording from late on 18 July (SAB station, IGP)
A strong seismic swarm has occurred during the past days under the volcano, culminating in a magnitude 5.9 earthquake on 16 July. The swarm consisted almost entirely of volcanic-tectonic quakes, that relate to rock fracturing due to rapid pressure changes and might be caused by an intrusion of magma. IGP reports that up to 1500 earthquakes were recorded per day.
At the moment, the swarm still continues, but is decreasing. No changes of activity have been noticed at the surface. The number of long-period quakes (thought to correspond to internal movements of magma, gasses and other fluids) has remained low.

The crater of Sabancaya volcano on 21 May 2013 (IGP)
The volcano has remained quiet, but is still showing signs of unrest. IGP scientists found evidence of eruptive activity (no fresh lava or pyroclastic deposits) inside the crater of of the volcano during a helicopter survey on 21 May. Only steaming and degassing were observed from the crater, that measures about 300-350 m in diameter and is 200 m deep. read all
