Reykjanes (Iceland) - Report for 24 September-30 September 2025 - NEW

Datum: Tue, 30 Sep 2025 04:08:05 -0400

Beschreibung:

The Icelandic Meteorological Office (IMO) reported that by 23 September around 10 million cubic meters of magma had accumulated beneath Svartsengi since the last eruption within the Reykjanes volcanic system ended on 5 August. Data showed that magma was accumulating at around 4 km depth. The rate of magma accumulation was steady; model calculations based on deformation measurements indicated that by 27 September the volume may reach 11 million cubic meters, a volume that in some previous cases was followed by eruptions. Since the likelihood of an eruption had increased, IMO raised the Volcanic Alert Level System (VAL) to 2 (on a scale of 0-3) on 25 September and concurrently a risk assessment map of the area was also updated.

Sabancaya (Peru) - Report for 24 September-30 September 2025 - NEW

Datum: Tue, 30 Sep 2025 04:08:05 -0400

Beschreibung:

The Instituto Geofísico del Perú?s (IGP) Centro Vulcanológico Nacional (CENVUL) reported that daily gas-and-steam plumes at Sabancaya rose 300-1,300 m above the crater rim and drifted less than 10 km in multiple directions during 23-29 September. Thermal anomalies on the summit crater floor were detected almost daily. The Alert Level remained at Orange (the third level on a four-color scale) and the public was warned to stay outside of a 12 km radius from the summit.

Ambae (Vanuatu) - Report for 24 September-30 September 2025

Datum: Tue, 30 Sep 2025 04:08:05 -0400

Beschreibung:

The Vanuatu Meteorology and Geohazards Department (VMGD) reported ongoing unrest at Ambae during the month of September based on seismic and satellite data, webcam images, and field observations. Sulfur dioxide emissions were identified in satellite images during 1-10, 12-14, and 16-21 September. A very low-level thermal anomaly was also detected in satellite images during 11 and 20-22 September. Steam and/or gas emissions were visible in satellite and webcam observations on 12 September. 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 24 September-30 September 2025

Datum: Tue, 30 Sep 2025 04:08:05 -0400

Beschreibung:

The Vanuatu Meteorology and Geohazards Department (VMGD) reported ongoing unrest at Ambrym during September. A weak thermal anomaly was detected in satellite images on 4 and 12 September. Seismic data confirmed ongoing unrest. 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.
