SERNAGEOMIN changed the level of alert of Calbuco to  amarilla.

Over the past three days, the seismic activity of the volcano has increased, with a total of 161 volcano-tectonic earthquakes, in connection with the fracturing of rocks, located between 8 and 10 km deep and 1-4 km. the active crater.

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.
