An inspection of the crater by staff from the Observatorio Vulcanológico del Sur (OVS) on 1 October showed that temperatures at the fumaroles remain elevated (near 400 deg C) and volcanic gas emissions had slightly increased over the past weeks.
According to the latest report by INGEMMET, seismic activity, in particular rock-fracturing earthquakes increased significantly at the volcano during the first days of October. However, according to the latest report by OVS, no such increase is mentioned. Overall seismic activity has been low during the past weeks.
No other significant signs of volcanic activity (e.g. deformation, thermal anomalies, explosions) have been detected recently. According to both OVS / INGEMMET, a slow magmatic intrusion continues to occur under the volcano. Whether or not this will lead to a new eruption is impossible to predict, but authorities continue to monitor the volcano and recommend people living near Sabancaya to closely follow the official reports.

Since mid June, an increase in internal activity has been recorded at the volcano. The Geophysical Institute of Peru reported a swarm of shallow earthquakes in an area at 6 km depth approx. 7 km north of the volcano's summit. In addition, increased degassing has been observed. Both are likely signs of a probable magmatic intrusion. ... [more]
