Datum: Thu, 08 Jan 2026 01:29:29 -0400

Beschreibung:

The Wellington Volcanic Ash Advisory Center (VAAC) reported that low-level ash plumes at Ambae rose 1.5 km (5,000 ft) a.s.l. and drifted N during 4-5 January. According to the Vanuatu Meteorology and Geohazards Department (VMGD) the Alert Level remained at 2 (on a scale of 0-5), and the public was warned to stay outside of Danger Zone A, defined as a 2-km radius around the active vents in Lake Voui, and to stay away from drainages during heavy rains.

Ambrym (Vanuatu) - Report for 1 January-7 January 2026 - NEW

Datum: Thu, 08 Jan 2026 01:29:29 -0400

Beschreibung:

The Vanuatu Meteorology and Geohazards Department (VMGD) reported that at 0650 on 8 January an ash plume at Ambrym was identified in satellite images. Seismic data confirmed ongoing unrest that was characterized by volcanic tremor and several volcano-seismic events. The Alert Level remained at 2 (on a scale of 0-5). VMGD warned the public to stay outside of Permanent Danger Zone A, defined as a 1-km radius around Benbow Crater and a 2-km radius around Marum Crater, and to stay 500 m away from the ground cracks created by the December 2018 eruption.

Bur ni Telong (Indonesia) - Report for 1 January-7 January 2026 - NEW

Datum: Thu, 08 Jan 2026 01:29:29 -0400

Beschreibung:

The Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG) reported increased seismicity at Bur ni Telong on 30 December. A M 4.5 earthquake was detected at 2043 on 30 December and located about 5 km SW of the summit. The earthquake was followed by an increase in the number of deep volcanic earthquakes (VA) and shallow volcanic earthquakes (VB) beneath the volcano; by 2130 the seismic network had recorded 12 VAs, seven VBs, and one local tectonic earthquake. Four earthquakes were felt. Six more earthquakes located about 5 km SW were detected by 2245. Seismicity began to increase in July 2025, with events progressively getting stronger and closer to the surface, especially during November-December. At 2245 the Alert level was raised to 3 (the second highest level on a scale of 1-4) and the public was warned to stay 4 km away from the crater area and to avoid the fumarole and solfatara regions, especially during cloudy or rainy weather. According to news reports about 2,000 residents evacuated, mainly from Rembune (3 km WSW) and Pantan Pediangan (3 km W). A total of 16 earthquakes were recorded during 30-31 December, though seismicity decreased through the day on 31 December. On 3 January PVMBG lowered the Alert Level to 2 and the public was warned to stay 3 km away from the crater.

Etna (Italy) - Report for 1 January-7 January 2026 - NEW

Datum: Thu, 08 Jan 2026 01:29:29 -0400

Beschreibung:

The Sezione di Catania - Osservatorio Etneo (INGV) reported that eruptive activity at Etna?s summit craters continued during 29 December 2025-4 January 2026, characterized by explosive activity (mainly at Voragine Crater) and advancing lava flows in the Valle del Bove. Visual observations were often hindered by weather conditions. On 29 December explosive activity at the BN-2 vent at Bocca Nuova Crater and from the vent on the E flank of the Voragine Crater produced ash emissions that rapidly dispersed near the summit. The NE Crater (Northeast Crater) produced sporadic ash emissions and flashes of incandescence visible at night. Beginning on 30 December summit activity was concentrated at Voragine Crater with Strombolian activity and minor ash emissions. Beginning at around 1730 on 1 January, as the weather conditions cleared, lava flows were visible within the Valle del Bove in webcam images. Satellite images and field observations conducted by INGV scientists revealed that at least two vents had opened just upslope of Mount Simone at about 2,050-2,100 m elevation. Intense spattering activity had built hornitos around the vents. By 1900 the lava flow field consisted of several branches, with the longest branch reaching an area just S of Rocca Musarra, around 1,570 m elevation. On 2 January the most advanced lava flow had reached 1,420 m elevation and was about 2.8 km long. During the next day, on 3 January, INGV scientists observed the flow field and launched drones. They noted that the longest branch had advanced 330 m since the previous day, reaching 1,380 m elevation, and had a total length of 3.14 km. The most active part of the flow field was between 1,800 m and 1,700 m elevation; this area consisted of several active branches, some newer flows overlapped older flows. The flow field area was an estimated 550,000 square meters. Lava flows were active on 4 January, though the longest flow was stationary and cooling.

Kikai (Japan) - Report for 1 January-7 January 2026 - NEW

Datum: Thu, 08 Jan 2026 01:29:29 -0400

Beschreibung:

The Japan Meteorological Agency (JMA) reported that after the 29 December 2025 eruption at Iodake Crater (at Satsuma Iwo-jima, a subaerial part of Kikai?s NW caldera rim), no additional eruptive activity was detected through 2 January 2026. Nighttime incandescence at the summit was detected in webcam images. Seismicity remained low. The Alert Level remained at 2 (on a 5-level scale), and residents were warned to be cautious within 500 m away from Iodake Crater.
