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.

Long-period seismicity (fluid movements) decreased to averaged of 72 events / day, while shallow rock-fracturing quakes remained frequent with an average of 9 per day.
