Whakaari/White Island volcano (New Zealand) - Smithsonian / USGS Weekly Volcanic Activity Report for 7 May-13 May 2025 (Continuing Activity)

On 13 May GeoNet reported near-continuous emissions of gas, steam, and minor amounts of ash at Whakaari/White Island based on visual observations during overflights, visual observations from the Bay of Plenty coast, and from webcams located at Whakatane and Te Kaha. Additionally, minor amounts of ash were identified in satellite data as reported by the Wellington Volcanic Ash Advisory Center (VAAC). As seen from the coast, the plume occasionally rose 300-600 m above the summit during calm weather conditions, but during windier conditions the plume was lower and was visible downwind for tens of kilometers.
Flights were occasionally canceled due to ash in the air. During overflights, scientists observed that the vent has not notably changed in size or shape. Although the vent temperature had increased to 460 degrees Celsius, it was still below the high of 650 degrees Celsius recorded in 2020 and 2021.
Elevated temperatures were visible at night in the Te Kaha camera near infrared images. There were fewer new impact craters around the vent, suggesting less explosive activity. Temperature measurements, sulfur dioxide emissions identified in satellite data, and the amount of ash in the emissions remained steady over the past few months.
The Volcanic Alert Level remained at 3 (on a scale of 0-5) and the Aviation Color Code remained at Orange (the second highest level on a four-color scale). GeoNet stated that the Alert Levels were reflective of the current level of activity, but there was uncertainty due to the lack of consistent, usable, real-time monitoring data; GeoNet relies on remote cameras, satellite images, and periodic overflights to monitor Whakaari.

Merapi volcano (Indonesia) - Smithsonian / USGS Weekly Volcanic Activity Report for 7 May-13 May 2025 (Continuing Activity)

The Balai Penyelidikan dan Pengembangan Teknologi Kebencanaan Geologi (BPPTKG) reported that the eruption at Merapi (on Java) continued during 2-8 May. Seismicity remained at high levels. The SW lava dome produced 41 lava avalanches that traveled as far as 2 km SW down the Bebeng drainage, 10 that traveled as far as 1.8 km SW down the Krasak drainage, and 73 that traveled as far as 2 km W down the Sat/Putih drainage.
Small morphological changes to the SW lava dome resulted from continuing effusion and minor collapses of material. The Alert Level remained at 3 (on a scale of 1-4), and the public was warned to stay 3-7 km away from the summit, based on location.

Poas volcano (Costa Rica) - Smithsonian / USGS Weekly Volcanic Activity Report for 7 May-13 May 2025 (Continuing Activity)

The Observatorio Vulcanológico y Sismológico de Costa Rica-Universidad Nacional (OVSICORI-UNA) reported continuing gas-and-steam emissions that occasionally contained ash Poás during 6-13 May. Inflation continued to be detected. Sulfur dioxide emissions were as high as 1,703 tons per day (t/d) on 6 May.
Some water had pooled at Boca C and was bubbling based on a drone observation that same day. Ash was very low or not detected in the steam-and-gas plumes during 5-7 May. Overnight during 7-8 May incandescence reflected in the emissions from sulfur combustion suggested temperatures less than 300 degrees Celsius.
A significant eruptive event was detected in seismic and acoustic data at 1404 on 8 May and lasted for two minutes. Weather conditions prevented direct visual observations of the event, though the seismic and acoustic data suggested an ash-and-gas plume rising into the 1-4 km high range; wind direction was to the SW. Bubbling at Boca C was again observed.
Overnight during 8-9 May intense incandescence emanated from Boca A and a dense steam plume with minor ash content was observed. Continuous gas-and-steam plumes drifted SW during 12-13 May; the plumes were more intense from Boca A, where overnight incandescence was also observed. The volcano’s Alert Level remained at 3 (the second highest level on a four-level scale) and the Aviation Color Code remained at Orange (the second highest color on a four-color scale).

Stromboli volcano (Italy) - Smithsonian / USGS Weekly Volcanic Activity Report for 7 May-13 May 2025 (Continuing Activity)

The Sezione di Catania - Osservatorio Etneo (INGV) reported that eruptive activity continued at Stromboli during 5-11 May. Webcam images showed Strombolian activity at four vents in Area N within the upper part of the Sciara del Fuoco and from at least two vents in Area C-S (South-Central Crater) on the crater terrace. The vents in Area N continued to produce low- to medium-intensity explosions at a rate of 6-9 events per hour, ejecting lapilli and bombs less than 150 m above the vents.
Low- to medium-intensity explosions at the vents in Area C-S ejected ash, bombs, and lapilli above the vent at a rate of 2-5 events per hour. The Alert Level remained at Yellow (the second lowest level on a four-level scale) according to the Dipartimento della Protezione Civile.

Santa Maria volcano (Guatemala) - Smithsonian / USGS Weekly Volcanic Activity Report for 7 May-13 May 2025 (Continuing Activity)

The Instituto Nacional de Sismología, Vulcanología, Meteorología e Hidrología (INSIVUMEH) reported ongoing eruptive activity at Santa Maria’s Santiaguito dome complex during 6-13 May with continuing lava extrusion at Caliente dome. Daily explosions, as many as five per hour when reported, sometimes generated gas-and-ash plumes that rose as high as 1 km above the dome and possibly drifted as far as 15 km E, S, SW, and W. Effusion of blocky lava and collapses of material produced block avalanches that descended multiple flanks; the collapsed material sometimes produced short pyroclastic flows.
Incandescence was visible at Caliente dome and upper part of the SW flank lava flow. During the evening of 10 May heavy rainfall generated lahars in the Tambor drainage (SSW) that carried blocks up to 1 m in diameter mixed with fine sediment, tree trunks, and branches. Ashfall was reported in San Marcos (10 km SW), Loma Linda (7 km W), and Palajunoj (17 km SSW) during 12-13 May.

Semeru volcano (Indonesia) - Smithsonian / USGS Weekly Volcanic Activity Report for 7 May-13 May 2025 (Continuing Activity)

The Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG) reported that activity continued at Semeru during 7-13 May, with multiple daily eruptive events recorded by the seismic network. Daily white-and-gray ash plumes rose 400-1,000 m above the summit and drifted in multiple directions. Weather clouds mostly obscured views on 7 May.
The Alert Level remained at 2 (the second lowest level on a scale of 1-4). The public was warned to stay at least 5 km away from the summit in all directions, 13 km from the summit to the SE, 500 m from the banks of the Kobokan drainage as far as 17 km from the summit, and to avoid other drainages including the Bang, Kembar, and Sat, due to lahar, avalanche, and pyroclastic flow hazards.

Marapi volcano (Western Sumatra, Indonesia): strong eruption sent ash to 4,5 km altitude yesterday

The ash-laden plume could be seen rising from the Marapi volcano yesterday (image: Pusat Vulkanologi dan Mitigasi Bencana Geologi)

A spectacular eruption took place from the volcano yesterday.
At about 09:42 local time today, a powerful explosion generated a dense dark ash column. The towering pillar of gas, ash emissions and lava bombs rose about 1600 meters above the summit in the northeastern direction.
There is a 3 km exclusion zone around the Verbeek Crater in place.
