The Buenos Aires VAAC reported that during 25-28 June there was continuous steam and possible ash emission from Ubinas. In a press release from 30 June, IGP noted minimal releases of ash and gas emissions had been observed during the previous days. Gas-and-ash plumes observed on 30 June rose 1.8 km above the crater.
Small ash emission from Ubinas volcano on Saturday
Activity has been lower during the past days. Ash emissions have become less frequent and smaller.
Explosion at Ubinas volcano today
Mild to moderate explosive activity continues with little changes. A number of smaller explosions and phase of continuous ash emissions occurred today at the volcano:
INGEMMET reported intermittent explosions from Ubinas along with continuing daily tremor and long-period earthquales during 18-23 June. Two explosions were noted on 18 June, as were six gas-and-ash emissions that generated diffuse plumes 400-700 m above the summit. Ashfall was reported in Querapi (located 4 km S).
Light ash emission from Ubinas today
Near-continuous, but light ash emissions interrupted by sporadic explosions continue at the volcano. Two stronger explosions on 12 and 13 June produced ash plumes that rose 2.5-3.5 km above the summit.
In a 12 June press release, IGP's Observatorio Volcanologico de Arequipa (IGP-OVA) reported that activity at Ubinas had decreased since April, however periods of intense tremor mainly associated with ash emissions continued to be detected. Ashfall affected areas around the volcano, especially within 6 km E and SSW. An IGP update on 17 June noted a small explosion at 1335 that day that sent ash 1,800 m above the crater, to an altitude of about 7,400 m (24,500 ft) a.s.l.
Explosion at Ubinas volcano yesterday
A relatively strong explosion occurred yesterday morning at the volcano, followed by ongoing ash emissions. Overall, the activity at the volcano has been showing again an increasing trend.
In a press release from 5 June, IGP's Observatorio Volcanologico de Arequipa (IGP-OVA) and Observatorio Vulcanológico del INGEMMET (OVI) reported that an Alert Level Orange continued for residents affected by the Ubinas eruption. Residents of Querapi and Tonohaya remained evacuated. The report noted that a significant and continuous release of ash emissions and gasses were observed during the previous days.

Ash explosion at Ubinas volcano this morning
Activity continues to show an overall decreasing trend. A small explosion occurred this morning at the volcano, producing a dark ash plume that rose several hundred meters.

Observatorio Vulcanológico del INGEMMET (OVI) reported that during 28-29 May ash emissions at Ubinas continued; gas-and-ash plumes rose .6-2.5 km above the crater and drifted ESE. Ashfall was reported in various towns downwind of the plumes, including Querapi (4 km S), Ubinas (6.5 km SSE), Escacha, Chojata, San Miguel, and Tonohaya. The Buenos Aires VAAC reported that seismicity fluctuated during 2-3 June.

IGP's Observatorio Volcanologico de Arequipa (IGP-OVA) and Observatorio Vulcanológico del INGEMMET (OVI) reported that during 14-16 May emissions at Ubinas continued. On 14 May emissions with minor amounts of ash rose .6-1.8 km above the crater. An explosion at 1902 on 14 May ejected fragments around the crater and caused thick ashfall in Chojata and Escacha.

Seismic activity at Ubinas during the past weeks (IGP)
Activity has again increased a bit during the past days. Along with more frequent hybrid earthquakes indicating rising magma, the number of small to moderate ash emissions has increased again.

Current seismic activity at Ubinas (UB1 station, IGP)
The current eruptive phase might be approaching an end. Since the second half of April, visual and seismic activity at the volcano have been decreasing. Explosions and ash emissions have almost ceased, although there are still some occasional bursts.

IGP's Observatorio Volcanologico de Arequipa (IGP-OVA) and Observatorio Vulcanológico del INGEMMET (OVI) reported that during 7-12 May gas-and-ash plumes, sometimes with only minor amounts of ash, rose 0.6-3 km above the crater. Ash fell in various towns downwind of the plumes including Querapi (4 km S), Ubinas (6.5 km SSE), Escacha, Anascapa, San Miguel, and Tonohaya. Significant ashfall was reported in Santa Rosa de Phara on 8 May.

IGP's Observatorio Volcanologico de Arequipa (IGP-OVA) and Observatorio Vulcanológico del INGEMMET (OVI) reported that during 30 April-1 May seismic activity at Ubinas increased significantly, and then declined through 6 May. Explosions generated ash plumes that rose 0.2-3 km above the crater and drifted in multiple directions, especially to the S, SE, E, and NE.

Ash emission from Ubinas this afternoon
The volcano's activity increases. As more magma arrives to build up the new lava dome in the summit crater, more gasses are being released as well and cause near-constant explosive activity with moderately strong ash emissions at the moment (see video).

Explosion at Ubinas yesterday (IGP)
Activity at the volcano has been increasing over the past week, both the number and size of explosions and the corresponding seismic activity. Explosions on 9 April produced ash plumes that reached up to 3 km height, which is a significant increase compared to the smaller ones that had been occurring previously with 1.5-2 km tall plumes. Light ash fall occurred in areas to the NE, in areas up to 20 km distance including the villages Lloque, Chojata, and Ichuna.
