Ambae (Vanuatu) | Continuing eruption
|
|
 AmbaeVanuatu Volcanic Arc |
The Volcanic Ash Advisory Center Global reported that the eruption continued at Ambae on 26 August 2026 (local). The eruption that began at 0940 on 25 August UTC continued through 26 August. Ash plumes rose 3–7.6 km (10,000–25,000 ft) above sea level during the day, well below the 16.5 km recorded on 25 August, and drifted N and NE through the morning. A strong sulfur dioxide signal was reported in advisories through 1125. At 1518 a plume at 3 km drifted NW while the older plume E of the volcano dissipated. A new eruption cloud was observed at the volcano at 1730, and at 1851 it rose to 4.6 km (15,000 ft) above sea level, about 3.1 km above the vent, and drifted E while the older plume continued to dissipate. Another eruption at 2300 produced a second plume that also rose to 4.6 km and drifted E. According to the Vanuatu Daily Post, ashfall was reported across the E and NE coast of Ambae overnight, following eruptions that began after 0800 UTC. At Saratamata (21 km NE) people woke to heavy ash covering the area and described the falling ash as sounding like rain when it reached the ground. At Lolowaï (20 km NE), ashfall contaminated rainwater collected in household tanks, which was no longer considered safe to drink, and damaged surface crops. Ambaebulu School (19 km NE), which has about 270 students, was advised by the Provincial Education Office to buy bottled water. Ashfall in South Ambae was reported as heavier, and residents there described material falling like stones. Residents on the E side of the island described this as the first ashfall of 2026 on that side.

The Center for Volcanology and Geological Hazard/Pusat Vulkanologi dan Mitigasi Bencana Geologi (CVGHM/PVMBG) reported that the eruption continued at Dukono on 26 August 2026 (local). Ashfall covered the solar panel at the field monitoring station, draining the battery and taking the station offline, so no seismic data were available for the day. The alert level remained at "Level 2 - Alert" (on a 4-level scale).

The United States Geological Survey (USGS) and United States Geological Survey - Hawaiian Volcano Observatory (USGS-HVO) reported that the eruption continued at Kilauea between 25 August 2026 (local) and 26 August 2026 (local). Glow and occasional flames were visible overnight at the north and west vents. The north vent dimmed slightly around 0200 and the west vent glow became weaker and more sporadic. The south vent remained dark and appeared partly filled by north vent spatter erupted the previous day. Lava flows along the north and south sides of Halemaʻumaʻu Crater continued to advance after the episode ended but slowed greatly in the early morning. Only a few points of incandescence remained visible by dawn. A small slump-driven flow was active on the south side of the west vent from about 0230 until dawn. Summit inflation resumed immediately when fountaining ceased. The Uēkahuna tiltmeter recorded 1.4 microradians of inflation before mild deflation began around 0200. As of the morning the tiltmeter had recovered 0.9 of the 12.7 microradians lost during the episode. Low-frequency seismic bursts began when the episode ceased and continued through the morning. Three shallow earthquakes were recorded beneath the summit region. The Volcano Alert Level remained at Advisory and the Aviation Color Code at Yellow.

|
 PuracéNorthern Andean Volcanic Arc |
The Servicio Geológico Colombiano (SGC) reported that the eruption continued at Puracé between 25 August 2026 (local) and 26 August 2026 (local). Tremor associated with fluid dynamics in the volcanic conduits dominated the seismic record and was located beneath the Puracé Crater at depths of less than 1 km. An ML 2.7 earthquake occurred 8 km NE of the crater at a depth of 9 km, followed by several aftershocks. The largest was ML 1.3. SGC reported no change in eruptive behavior after these earthquakes. The remaining rock-fracturing seismicity was located beneath the Piocollo Crater at 1–2 km depth. One ash emission at 0222 was confirmed visually on the Mina infrared webcam despite adverse atmospheric conditions. Its maximum measured height was 700 m above the vent, but the column exceeded the camera's field of view and may have been higher. Sulfur dioxide emission measured 1,300 tonnes per day and dispersed NW. Flux remained above the known average for the volcano. Soil carbon dioxide concentrations continued to rise. No thermal anomalies at the crater floor were reported on the MIROVA platform. Slow ground deformation persisted between the Puracé, Piocollo, and Curiquinga volcanoes.

The Daily Volcanic Activity Report is a cooperative project between the Smithsonian's Global Volcanism Program and the USGS Volcano Disaster Assistance Program. The report is published Monday-Friday, and roughly describes volcanic activity that has occurred and been reported upon during the preceding 24 hours. Because data for these reports are gathered Monday through Friday, reports published on Mondays may be incomplete and/or include events that occurred over the weekend. The report is not a comprehensive list of all currently erupting volcanoes, but rather a summary of activity that meets criteria described below.
Daily Volcanic Activity Reports are preliminary and subject to change. Carefully reviewed, detailed narratives over longer time periods are published as the Weekly Volcanic Activity Reports and reports of the Bulletin of the Global Volcanism Network available through volcano profile pages. Daily Volcanic Activity Reports should not be used in place of primary information from volcano observatories, particularly to inform decision-making during volcanic unrest.
The Daily Volcanic Activity Report does not necessarily include all volcanic activity on Earth during each day. The overall goal is to document the alert level as well as more detailed daily information for a prioritized list of volcanoes.
Since these reports are intended to provide timely information about global volcanism on a daily basis, they are generated rapidly by summarizing volcanic reports from various sources (including volcano observatories and Volcanic Ash Advisory Centers), with little time for verification. The accuracy of the Daily Volcanic Activity Report is dependent upon the quality and content of the volcanic activity reports being collected, and accordingly may include some events ultimately found to be erroneous or misleading. Reports published in other products cover longer time periods, providing an opportunity for additional review. Because of our emphasis on rapid reporting on the web we have avoided diacritical marks.
Rapidly developing events lead to coverage that is often fragmentary. Volcanic eruptions, including their plumes and associated atmospheric effects, are complex phenomena that may require months to years of data analysis to create a comprehensive summary and interpretation of events. Preliminary accounts sometimes contain errors and "false alarms," and accordingly, this report may include some events ultimately found to be erroneous or misleading.
The Volcano List tab contains additional columns for Country, Volcanic Region, and Last Known Eruption. The country name is present for informational purposes only, and may not correspond to official US Government policy. Multiple hyphenated countries indicate a volcano that is present along a border along those countries; additional information is available about disputed areas. The names of Volcanic Regions reflect common scientific or geographic names combined with terms indicative of the general tectonic environment, and have no political implications. The "Last Known Activity" field presents start and stop dates using data available from the most recent eruption update, with "(continuing)" indicating a volcanco on the Current Eruptions page. Volcanoes may be noted on a Daily Report as having eruptive activity but not shown as having a current eruption due to a new eruption starting after the last update, which are generally done every 6-8 weeks. This field will always show the latest eruption dates regardless of the date selected for reports.
