Seismic unrest continues at the volcanic massif of Chiles and Cerro Negro. However, it decreased during the past week with less than 700 events recorded, compared to 1500-1800 per week during the month before.
Most earthquakes were associated with internal rock fracturing and located at shallow 1-7 km depth in an area 4 km SW of the Chiles dome. Magnitudes reached 2.7 and some quakes were felt.
Slight deformation has been detected at the Chiles dome as well.
