Inflation has been detected by the inclinometer just 4.5 km west of the active crater, showing an accumulated variation of 60μrad.

Previous observations suggest the reactivation of a deep magma chamber under the influence of seismic activity and deformation, involving an internal imbalance that could culminate in an eruptive activity over the next weeks or months.

 

The most affected populations are Ensenada, Correntoso, Colonia Rio Su and Alerce.

The technical amarilla alert is accompanied by a high risk area of ​​2 km around the main crater.
