Lascar (Chile) - Report for 5 February-11 February 2026 - New Eruptive Activity

Datum: Thu, 12 Feb 2026 04:36:09 -0400

Beschreibung:

According to the Sistema y Servicio Nacional de Prevención y Repuesta Ante Desastres (SENAPRED) and the Servicio Geológico Minero Argentino (SEGEMAR) reported eruptive activity at Láscar on 8 February. The seismic network recorded increased volcano-tectonic activity associated with rock fracturing. A tremor signal, associated with fluid movement, was recorded along with a gas-and-ash plume that rose 1.1 km above the crater rim and drifted NE. The Alert Level remained at Green (the lowest level on a four-color scale).

Sheveluch (Russia) - Report for 5 February-11 February 2026 - New Eruptive Activity

Datum: Thu, 12 Feb 2026 04:36:09 -0400

Beschreibung:

The Kamchatkan Volcanic Eruption Response Team (KVERT) reported continuing eruptive activity at Sheveluch, from the domes along the N margins of Young Sheveluch, during 5-11 February. A daily thermal anomaly was identified in satellite images and explosions occasionally produced tall ash plumes. At 0040 on 5 February explosions produced ash plumes identified in satellite images that rose to 9.8 km (32,200 ft) a.s.l. and drifted 42 km N. At 0128 the Aviation Color Code was raised to Red (the highest level on a four-color scale). A few hours later explosions generated an ash plume that rose to 9 km (29,500 ft) a.s.l. and drifted 165 km NW. KVERT lowered the Aviation Color Code to Orange at 0702, noting that no new ash emissions were identified. Later that day, at 2320, explosions ash plumes from explosions rose to 10 km (32,800 ft) a.s.l. and drifted 33 km NW. The Aviation Color Code was raised to Red about an hour later, at 0024 on 6 February. The Aviation Color Code was lowered back to Orange at 0241; there were no new ash emissions, though a previous ash cloud was visible drifting 180 km NW at an altitude of 10 km. The Far Eastern Branch of the Russian Academy of Sciences (FEB RAS) reported that ash plumes around 0520, 1120, and 1720 rose to 8.5 km (27,900 ft) a.s.l. and drifted NW according to Tokyo Volcanic Ash Advisory Center (VAAC) notices. Explosions sent ash plumes to 10.5 km (34,400 ft) a.s.l. by 2320 on 6 February, prompting KVERT to raise the Aviation Color Code to Red at 0016 on 7 February. The ash plumes drifted 40 km NW. The Aviation Color Code was lowered back to Orange at 0116 because there were no new ash emissions; a previous ash cloud was drifting 130 km NW at an altitude of 9 km. According to FEB RAS ash plumes rose as high as 6.7 km (22,000 ft) a.s.l. and drifted NW during 0520-1720. An ash plume from explosions rose to 11.6 km (38,100 ft) a.s.l. at 0208 on 8 February and drifted 40 km NW. The Aviation Color Code was raised to Red at 0353 and then back to Orange at 0808. Satellite images showed an ash cloud at 9 km a.s.l. drifting 350 km NW. Weather clouds obscured satellite and webcam views on 9 February. At around 2130 on 10 February steam, gas, and ash plumes were visible in webcam images rising to 4 km (13,100 ft) a.s.l. and drifting E based on a FEB RAS report. Dates are based on UTC; specific events are in local time where noted.

Bulusan (Philippines) - Report for 5 February-11 February 2026 - Unrest

Datum: Thu, 12 Feb 2026 04:36:09 -0400

Beschreibung:

The Philippine Institute of Volcanology and Seismology (PHIVOLCS) lowered the Alert Level for Bulusan to ?0, Normal? (the lowest level on a scale of 0-5) at 2300 on 6 February, noting that monitoring showed declining activity over about the past 8 months. Specifically, volcanic gases declined to baseline levels after mid-June 2025, the E and S flanks had been deflating since October and November 2025, respectively, and volcanic earthquakes had declined to baseline levels (0-5 earthquakes per day) in early December 2025 and remained low. The public was reminded not to enter the 4-km-radius Permanent Danger Zone (PDZ) and to be vigilant within the 2-km Extended Danger Zone (EDZ) on the SE flank.

Dieng Volcanic Complex (Indonesia) - Report for 5 February-11 February 2026 - Unrest

Datum: Thu, 12 Feb 2026 04:36:09 -0400

Beschreibung:

The Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG) lowered the Alert Level for Dieng Volcanic Complex to 1 (on a scale of 1-4) on 9 February. The public was warned to stay 200 m away from Sileri Crater, to not approach Timbang Crater, and to be vigilant when digging in the area due to risks of carbon dioxide gas exposure.

Iliwerung (Indonesia) - Report for 5 February-11 February 2026 - Unrest

Datum: Thu, 12 Feb 2026 04:36:09 -0400

Beschreibung:

The Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG) reported decreasing seismicity at Iliwerung in 2026 following a few periods of increased seismicity in 2025, including a felt earthquake on 29 November, that may have indicated increase pressure within the edifice. Data did not indicate unrest at shallower levels. At 1400 om 11 February the Alert level was lowered to 1 (on a scale of 1-4) and the public was warned to stay away from the crater area and to be cautious around the Bualan area.
