Karangetang (Indonesia) - Report for 27 August-2 September 2026 - New Eruptive Activity

Datum: Thu, 03 Sep 2026 04:12:58 -0400

Beschreibung:

The Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG) and a news source reported that an eruption at Karangetang?s North Crater (Kawah Dua) continued during 27 August-2 September. Daily white plumes rose as high as 500 m above the summit and drifted in various directions. Incandescence at the North Crater and from lava flows and/or incandescent avalanches on the flanks was visible in some webcam images throughout the week. Seismicity remained at high levels and rumbling sounds were occasionally heard. The Alert Level remained at 2 (on a scale of 1-4) and the public was advised to stay 1.5 km away from both craters, with an extension to 2.5 km on the NW and SW flanks of North Crater.

Klyuchevskoy (Russia) - Report for 27 August-2 September 2026 - New Eruptive Activity

Datum: Thu, 03 Sep 2026 04:12:58 -0400

Beschreibung:

The Kamchatkan Volcanic Eruption Response Team (KVERT) reported that the eruption at Klyuchevskoy continued at the summit crater during 27 August-2 September. A daily thermal anomaly was identified in satellite images. Daily ash plumes rose as high as 7 km (23,000 ft) a.s.l. and drifted as far as 170 km NE and E during 27-30 August. The Aviation Color Code remained at Orange (the second highest level on a four-color scale). Dates are based on UTC; specific events are in local time where noted.

Krakatau (Indonesia) - Report for 27 August-2 September 2026 - New Eruptive Activity

Datum: Thu, 03 Sep 2026 04:12:58 -0400

Beschreibung:

The Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG) reported ongoing eruptive activity at Krakatau during 27 August-2 September. Ash-and-gas plumes that were a mixture of white, gray, and black colors rose 100-400 m above the summit and drifted mainly W, NW, N, and NE during 27-31 August. A webcam image on 27 August showed incandescent material being ejected above the crater. White plumes were visible rising as high as 200 m and drifting SW, W, and NW during 1-2 September. The Alert Level remained at 3 (on a scale of 1-4) and the public was advised to stay 3 km away from summit.

Ranakah (Indonesia) - Report for 27 August-2 September 2026 - New Unrest

Datum: Thu, 03 Sep 2026 04:12:58 -0400

Beschreibung:

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 of August, until 1 September when over 100 deep volcanic earthquakes were recorded. Drone overflights revealed denser plumes rising from the solfataras W of the lava dome on 25 August and more diffuse plumes rising from the same area on 1 September. No significant changes at the lava dome were observed during the overflights despite earthquake-triggered landslides occurring in several areas at Ranakah on 18 and 20 August. At 2300 on 1 September the Alert Level was raised to 2 (on a scale of 1-4) and the public was warned to stay 1 km away from the crater.

Sinabung (Indonesia) - Report for 27 August-2 September 2026 - New Eruptive Activity

Datum: Thu, 03 Sep 2026 04:12:58 -0400

Beschreibung:

The Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG) reported that after a period of escalating unrest at Sinabung, which had been detected at least since May, a new eruption occurred on 31 August. During 1-30 August white-and-gray plumes rose as high as 1 km above the summit. Observers noted that the vegetation on the E flank yellowed and dried out. The seismic network recorded a total of one rockfall event, 14 earthquakes indicating emissions, two tornillo earthquakes, 29 low-frequency earthquakes, eight hybrid/multi-phase earthquakes, one shallow volcanic earthquake, and 141 deep volcanic earthquakes. On 28 August blue plumes descending the SE flank were observed. Prior to the eruption on 31 August a swarm was detected that consisted of 85 volcanic earthquakes, one earthquake indicating an emission, and one harmonic tremor. At 1017 a dense black ash plume rose around 3.5 km above the summit and drifted E and SE. The eruption lasted just over an hour based on seismic data. At 1230 the Alert Level was raised to 3 (the second highest level on a scale of 1-4). Though most of the exclusion zone remained at 3 km from the summit, it was increased to 6 km on the SE flank. Hotspots on the N flank were visible. According to a news source ashfall was reported in Berastagi City and residents were urged to wear masks while outside to avoid breathing in ash. Schools in high-risk areas implemented virtual learning for one day. Later that day, during 1800-2400, dense gray-and-brown plumes rose 200-500 m above the summit and drifted NE and E. On 1 September white-and-gray ash plumes rose as high as 600 m above the summit and drifted E, SE, and S, causing ashfall in areas to the SE. News sources reported that residents of Kuta Tengah Village and Payung Village (5 km SSW) were preemptively moved to evacuation centers following increased volcanic activity. Two flights on the Banda Aceh-Medan route were affected, one delayed and one canceled, due to ash in the air. At 0720 on 2 September a gray-to-brown ash plume rose about 1 km above the summit and drifted E and SE.
