A series of events beginning with one exhalation and followed by three explosions took place the evening of Sunday, October 2, into Monday morning.

The most energetic of the three explosions happened on Sunday evening at 10:50 p.m., measuring at 19 megajoules, just three hours after the first exhalation happened at 7:21 p.m. But this measured 0.6 megajoules. It was the late night explosion that caused ash coverage in the villages of Santa Rosa de Phara and Yanapuqui northeast of the volcano.

The explosions Monday morning at 4:24 a.m. and 5:52 a.m. led to ash within the town of Ubinas, which is southeast of the volcano with the wind carrying it southwest of the volcano also.

Due to fluctuations with rise of magma, the Scientific Committee of Permanent Monitoring of Volcano Ubinas, composed of the Volcano Observatory of the South (OVS) and the Volcanological Observatory of the INGEMMET (OVI), warned of possible reoccurrences and to take proper measures.
