Sabancaya volcano (Peru): ash emissions reported

Gas plume with possibly light ash from Sabancaya volcano (Peru)Light ash emissions were reported this morning, rising to 20,000 ft (6 km) altitude.
Seismic activity at the volcano remains low but above background. A slight increase in quakes related to internal fluid movements (gasses, water, magma) was noted during the past week.
Staff from the INGEMMET volcano observatory visited the summit area on 9 and 10 July and sampled ash that had been erupted during the recent weeks. A significant fraction of the ash was confirmed to originate from fresh ("juvenile") magma (as opposed to older weathered rock fragments), which confirms that the volcano has entered a magmatic eruptive phase.

Since mid June, an increase in internal activity has been recorded at the volcano. The Geophysical Institute of Peru reported a swarm of shallow earthquakes in an area at 6 km depth approx. 7 km north of the volcano's summit. In addition, increased degassing has been observed. Both are likely signs of a probable magmatic intrusion. ... [mehr]
