Guallatiri volcano (Northern Chile, Bolivia and Argentina, South America) activity update: increased seismic activity
Tuesday Jun 02, 2015 16:06 PM | DOOR: T
Elevated seismic activity since the night 30-31 May triggered SERNAGEOMIN to raise the alert level of the volcano to "yellow".
A swarm 22 earthquakes related to internal rock fracturing, possibly caused by rising magma, was registered shortly after midnight 30-31 May. A magnitude 3.7 quake occurred at 05:17 local time the next morning.
At the same time, slight deformation of the summit area of the volcano was detected as well, which would be consistent with a new magma intrusion at depth. No other changes (such as increased degassing, rock falls etc) have been noted.
