New signs of volcanic unrest - seismic swarms and ground inflation - have been detected at the volcano recently and SERNAGEOMIN raised the alert level of the volcano to yellow.
A seismic crisis began around February and currently has contained nearly 130 quakes of volcanic-tectonic origin (rock fracturing at depth) as well as fluid movements and volcanic tremor.
What is more worrying is the detection of a notable deformation of the area (inflation at a rate of about 20 cm / year) since the end of January.
The area has not had known eruptive activity during the past 3000 years, and these changes in activity need to be followed closely.
Following the report by SERNAGEOMIN, the government (ONEMI) decided to declare yellow alert for the town of San Clemente yesterday.
