The overall activity of Sabancaya remains at low levels in major seismic and satellite monitoring parameters. However, increased activity of VTP event type (associated with solid fracturing) in the last two days is observed. The average of seismic events for this period are: 73 LPs / day, 19 VTP and 7 Tremor / day. On the other hand, there have been significant proximal events in the northeast sector of the volcano crater, as a distal event , VT type , maximum magnitude M4,5, located 9 km from the crater.
The number of recorded events of proximal volcano tectonic , VTP type have increased on average with 19 VTP / day. 52 events VTP were localized, one of them of magnitude 3.9 M, which was held on December 8 at 7:53 p.m. UTC.
Sabancaya continues to emit steam and magmatic gases regularly. The maximum height of fumaroles showed emissions between 800 and 1600 meters above the crater. He could be discerned whitish fumaroles (steam) and sporadic emissions bluish (magmatic gases).
The satellite monitoring of the density of SO2 and thermal anomalies showed no significant values.
