Volcán · Ambrym (Vanuatu) - Report for 16 September-22 September 2026 - New Eruptive Activity
The Vanuatu Meteorology and Geo-Hazards Department (VMGD) reported that a new eruption at Ambrym likely started on 19 September. An intense thermal anomaly and high sulfur dioxide emissions were identified in satellite data; a volcanic cloud was visible in a satellite image at 0600. Ground-based observers reported dark gray ash-and-gas plumes rising from Marum Crater and rumbling sounds coming fr

Volcán · Sheveluch (Russia) - Report for 10 September-16 September 2026 - Continuing Eruptive Activity
The Kamchatkan Volcanic Eruption Response Team (KVERT) reported continuing lava effusion and explosive activity at the lava domes along the N crater floor of Young Sheveluch (on the SW flank of Old Sheveluch) during 9-15 September. A thermal anomaly was identified in satellite images on 11, 13, and 15 September; weather clouds occasionally obscured views. The Aviation Color Code remained at Orang

Volcán · Ranakah (Indonesia) - Report for 27 August-2 September 2026 - New Unrest
The Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG) reported increased unrest at Ranakah. Following the M 7.7 tectonic earthquake that occurred off the N coast Flores Island on 15 August there was an increase in the overall number of daily tectonic events. The number of deep volcanic earthquakes also increased, up to 35 events per day. Seismicity declined but remained high towards the end

Volcán · Poas (Costa Rica) - Report for 27 August-2 September 2026 - Continuing Eruptive Activity
The Observatorio Vulcanológico y Sismológico de Costa Rica-Universidad Nacional (OVSICORI-UNA) reported several small eruptions at Poás during 27 August-2 September with a few notable events. An eruption at 0235 on 27 August was comprised of two pulses based on seismic and acoustic data. The event ejected incandescent ballistics 600 m from the crater onto the E terrace. An eruptive event at 0048
