Volcanic-tectonic earthquakes at Sabancaya during 13-19 Jan (total: 282 recorded / IGP)
An increase in shallow earthquake activity with both characteristics of rock fracturing and disturbance of the hydrothermal system was noted last week. Most quakes occurred at shallow depth in an area few NNE of the volcano and south of the villages Pinchollo and Maca. The strongest quake of magnitude 3.8 on the evening of 19 Jan was felt by the local population.
Intermittent steam and bluish gas (SO2) emissions rose to a maximum of 1300 m above the crater. This and other monitored parameters showed no significant changes compared to the previous weeks.
