Degassing and ash plume from Ubinas during 14-16 May (IGP)
Activity remains low at the volcano. No explosions have occurred recently, only mild to moderate steam emissions, sometimes mixed with light ash, reaching up to 1-1.2 km height and drifting mainly east and northeast.
Instituto Geofísico del Perú (IGP) Observatorio Volcanológico del Sur (OVS) reported that during 19-26 May long-period earthquakes continued at the same rate while volcano-tectonic and hybrid events increased. Overall the dominant signal was spasmodic tremor associated with ash-and-steam emissions. While conducting fieldwork during 19-22 May, OVS staff observed persistent water vapor, gas, and ash emissions that rose 400 m.

Instituto Geofísico del Perú (IGP) Observatorio Volcanológico del Sur (OVS) reported that during 29 April-5 May long-period and tornillo-type earthquakes continued to decrease while volcano-tectonic events increased. Hybrid events were at a low level, however, an increase in the number of events were detected on 29 April. Overall the dominant signal was spasmodic tremor associated with ash-and-steam emissions.

According to Observatorio Volcanológico del Sur (OVS) and Observatorio Vulcanológico del INGEMMET (OVI), six explosions from Ubinas were recorded during 15-17 April, producing ash plumes that drifted 15 km SW, S, and SE. The largest ash plume, generated from an explosion detected at 0759 on 15 April, rose 3.5 km. The other explosions (at 1408 on 15 April, at 0600 on 16 April, and at 0743, 0936, and 1518 on 17 April) generated ash plumes that rose 1.5-1.8 km.

Ash emission from Ubinas yesterday and ash fall in Ubinas town (OVS)
After several months of calm, the volcano started to erupt yesterday morning again. An initial moderately strong explosion produced an ash plume that rose 2.5 km above the volcano and drifted SE to the Ubinas valley, where approx. 1.5 mm of ash fall occurred in 6 km distance.

INGEMMET's Observatorio Vulcanológico (OVI) reported that after a decline in activity at Ubinas during the previous five months two phreatic explosions were detected on 8 April. The explosions occurred at 0424 and 0550, generated ash-and-gas plumes that rose 2-2.5 km above the crater and drifted SE. According to Observatorio Volcanológico del Sur (OVS) snowmelt during 12-13 April led to large lahars that descended the S flank.

Instituto Geofísico del Perú (IGP) Observatorio Volcanológico del Sur (OVS) reported that during 10 February-17 March seismicity at Ubinas was generally low, although a hybrid event was detected on 11 March. Two main sources of seismicity were located 1 km W of the crater at depths of 1-3 km and 2 km NW at depths of 1-5 km. Water-vapor emissions rose as high as 1.5 km above the crater.
