Map of today's active volcanoes
: Activity at the volcano has increased over the past month and although still at levels considered within normal limited, can be described as elevated. It certainly is spectacular to view.

Seismic activity of Fuego volcano today (FG3 station, INSIVUMEH)
The activity at the volcano has again been increasing during the past days. The volcano observatory reported frequent moderate strombolian-type explosions ejecting glowing lava fragments to 250 m above the crater. Moderate to strong shock waves accompany the explosions.
Wed, 31 May 2017, 16:32The volcano has remained calm since the series of powerful explosions in Jan-Feb this year. A recent report by scientists from the Universidad de Colima mentioned ongoing seismic activity as well as very week explosions.

Erta Ale's eruption on SENTINEL 2 satellite imagery on 29 May 2017 (image: SENTINEL2 / ESA-Copernicus data; Composition / annotations: Culture Volcan)
The activity of the volcano remains intense and continues from both the summit (lava lake in south pit) and from the SE rift zone (lava lakes and lava flows).

OVSICORI-UNA reported that volcano-tectonic amplitude at Turrialba fluctuated from low to moderate levels during 30-31 May. Plumes of water vapor, magmatic gases, and material rose no higher than 300 m above the crater rim, sporadically contained ash, and drifted NW. On 3 June at 1930 an event produced an ash plume that rose 300 m and drifted SW.

Wed, 31 May 2017, 06:00Based on PVMBG observations, webcam and satellite images, and wind data, the Darwin VAAC reported that during 31 May-5 June ash plumes from Sinabung rose 3.4-5.5 km (11,000-18,000 ft) a.s.l. and drifted in multiple directions.

Observatorio Vulcanológico del Sur del IGP (OVS-IGP) and Observatorio Vulcanológico del INGEMMET (OVI) reported that for the second week in a row explosive activity at Sabancaya slightly increased from the previous week; there was an average of 47 explosions recorded per day during 29 May-4 June. Seismicity was dominated by long-period events, and the number and magnitude of hybrid events were low. Gas-and-ash plumes rose as high as 3 km above the crater rim and drifted more than 40 km E and SE.

Wed, 31 May 2017, 06:00Each day during 31 May-2 June CENAPRED reported 51-78 steam and gas emissions from Popocatépetl; the daily count increased to 144-276 during 2-5 June. Explosions were detected during 31 May-1 June (1-2 per day) and during 2-5 June (13-22 per day) though cloudy conditions prevented visual confirmation of ash, gas, and steam plumes. Observers noted material being ejected 200 m from the crater on 3 June.

OVSICORI-UNA reported that tremor amplitude at Poás fluctuated from low to medium levels during 30-31 May, often associated with the vigor of emissions of water vapor, magmatic gases, and material from vents. An event at 1200 on 2 June generated a plume consisting of water vapor, gases, and minor amounts of ash that rose 600 m above the crater. Another event recorded at 1353 could not be confirmed visually due to weather conditions.

Wed, 31 May 2017, 06:00Based on Observatorio Volcanológico de los Andes del Sur (OVDAS) - SERNAGEOMIN observations, ONEMI reported on 17 May that the number and magnitude of earthqaukes at Planchón-Peteroa had gradually declined during the past months, reaching baseline levels. Minor to no surface activity was noted. OVDAS-SERNAGEOMIN lowered the Alert Level to Green (the lowest level on a three-color scale), and ONEMI canceled the Yellow Alert for the communities of Molina (66 WNW), Curicó (68 km NW), Romeral (75 km NW), and Teno (68 km NW) that had been in place since 1 July 2016.

RVO reported that although weather clouds often obscured views of Manam during 1-7 June white emissions were periodically seen rising from Southern Crater and Main Crater. Seismicity was very low. The Alert Level remained at Stage 1.

KVERT reported that a weak thermal anomaly over Klyuchevskoy was identified in satellite images during 27 and 30-31 May and 2 June. Explosions during 1-2 June generated ash plumes that rose to 6 km (19,700 ft) a.s.l. and drifted about 400 km SSE.

Wed, 31 May 2017, 06:00During 31 May-6 June HVO reported that the lava lake continued to rise, fall, and spatter in Kilauea's Overlook crater. Webcams recorded incandescence from long-active sources within Pu'u 'O'o Crater, from a vent high on the NE flank of the cone, and from a small lava pond (which had many small spattering sites along the margin) in a pit on the W side of the crater. The 61G lava flow, originating from a vent on Pu'u 'O'o Crater's E flank, continued to enter the ocean at Kamokuna.

Wed, 31 May 2017, 06:00INSIVUMEH reported increased activity at Fuego on 1 June, characterized by an increase in the number of explosions (6-7 per hour) and ash plumes rising as high as 950 m above the crater and drifting W. Explosions generated shock waves that rattled structures in multiple areas including Panimaché I and II (8 km SW), Morelia (9 km SW), Santa Sofía (12 km SW), El Porvenir, and Sangre de Cristo (8 km WSW). Incandescent material was ejected as high as 500 m above the crater rim, and caused avalanches of material on the flanks.

On 2 June the Centro Universitario de Estudios e Investigaciones de Vulcanologia - Universidad de Colima reported that during the previous week seismic data revealed 21 high-frequency events, 14 long-period events, 1.7 hours of tremor, 12 landslides, and zero explosions. During 25-26 May sulfur dioxide emissions were low at 35-51 tons per day, close to the detectable limits.

Wed, 31 May 2017, 06:00AVO reported that no significant volcanic activity at Cleveland was detected in seismic, infrasound, or cloudy satellite images during 31 May-5 June. The webcam recorded steam emissions during periods of clear weather. Small low-frequency events were recorded by the seismic station located on the flank of the volcano beginning at 0939 on 6 June.

AVO reported that a short-duration (less than 10 minute) explosion at Bogoslof began at 1842 on 31 May based on seismic and infrasound data. A volcanic cloud identified in satellite images rose 7.3 km (24,000 ft) a.s.l., drifted WNW, and dissipated over the Bering Sea. The explosion was preceded by a several hour-long swarm of very small earthquakes.
