Etna (Italy) - Report for 2 July-8 July 2026 - New Eruptive Activity

Datum: Thu, 09 Jul 2026 02:29:28 -0400

Beschreibung:

The Sezione di Catania - Osservatorio Etneo (INGV) reported eruptive activity at Etna?s summit craters during 29 June-5 July characterized by lava effusion from two vents, Strombolian activity at Voragine Crater (VOR), and activity at a new fissure between VOR and Northeast Crater (NEC). Lava that began to effuse on 29 June from a vent on the E base of VOR, at 3,030 elevation, continued into July. INGV staff conducted a field survey on 2 July and observed that the lava flow field was active and complex, characterized by superimposed lava flows, ephemeral vents, and small lava tubes. Later that evening a small lava flow effused from a new vent, located between VOR and NEC at around 3,200 m elevation, and traveled 150 m before stopping the next morning on 3 July. The staff also observed that Strombolian activity from a pit crater on the upper E flank of VOR that began overnight during 26-27 June was continuing and intensified during 2-4 July. The flow from the vent on the E base of VOR became less active and stopped on 4 July. The lava-flow field was about 1.2 km long, with the most advanced lava flow reaching about 2,605 elevation, and about 87,000 square meters in size, based on drone photos from 2 July and a 5 July satellite image. On 5 July intense explosive activity began at several vents that formed along a new fissure that extended NNE from VOR to the NEC. Vents along the higher elevations of the fissure continuously produced ash while lower vents produced Strombolian activity. Ash plumes rose about 4.5 km a.s.l. and drifted mainly S, causing ashfall in several municipalities on the S flank, in the area between Rifugio Sapienza (5 km S) and Catania (around 29 km SSE), and the temporary closure of the Catania airport, about 30 km SSE. Lava effused from the NNE end of the fissure, traveled about 180 m, and flowed into NEC. Activity at the fissure began to decrease during the afternoon of 6 July and ceased during the early afternoon of 7 July. The Alert Level remained at Yellow (the second lowest level on a four-level scale) according to the Dipartimento della Protezione Civile.

Krakatau (Indonesia) - Report for 2 July-8 July 2026 - New Eruptive Activity

Datum: Thu, 09 Jul 2026 02:29:28 -0400

Beschreibung:

The Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG) reported that an eruption at Krakatau continued during 2-8 July. At 1405 on 2 July an eruption generated a gray-to-black ash plume that rose 200 m and drifted NW. The Aviation Color Code was raised to Orange (the second highest color on a four-color scale). At 1630 the Alert Level was raised to 3 (on a scale of 1-4), and the public was warned to stay 3 km away from the active crater. White-to-gray or white-to-brown ash plumes rose as high as 200 m during 3-4 July. Only white plumes were visible during 5-6 July, rising as high as 150 m. At 0821 on 7 July a dense gray plume rose 200 m and drifted NW; later that day plumes of various color combinations also rose as high as 200 m.

Mutnovsky (Russia) - Report for 2 July-8 July 2026 - New Eruptive Activity

Datum: Thu, 09 Jul 2026 02:29:28 -0400

Beschreibung:

The Kamchatkan Volcanic Eruption Response Team (KVERT) reported that an explosion at Mutnovsky occurred at 0819 on 1 July, lasted around three minutes, and generated an ash plume that rose 3.5 km above the summit and drifted several kilometers W. The Aviation Color Code (ACC) was raised to Orange (the second highest level on a four-color scale) at 2146. No additional explosions were detected; at 0420 on 2 July the ACC was lowered to Yellow. Weather clouds obscured satellite views during 2-5 July. A thermal anomaly was identified in satellite images during 6-7 July, but with decreasing temperatures. At 0316 on 9 July the ACC was lowered to Green. Dates are based on UTC; specific events are in local time where noted.

Aira (Japan) - Report for 2 July-8 July 2026 - Continuing Eruptive Activity

Datum: Thu, 09 Jul 2026 02:29:28 -0400

Beschreibung:

The Japan Meteorological Agency (JMA) reported ongoing eruptive activity at Minamidake Crater (Aira Caldera?s Sakurajima volcano) during 29 June-6 July. A very small eruptive event was detected on 29 June, and crater incandescence was visible in nighttime webcam images during 29 June-3 July. The Alert Level remained at 3 (on a 5-level scale), and the public was warned to be cautious within 2 km of both the Minimadake and Showa craters.

Ambae (Vanuatu) - Report for 2 July-8 July 2026 - Continuing Eruptive Activity

Datum: Thu, 09 Jul 2026 02:29:28 -0400

Beschreibung:

The Wellington Volcanic Ash Advisory Center (VAAC) reported that satellite and webcam views of Ambae showed continuous plumes of steam and sulfur dioxide, with intermittent ash signals, on 4 July. The plumes rose 2.1-2.3 km (7,000-8,000 ft) a.s.l. and drifted NW. During 5-6 July ash plumes that were sometimes continuous rose 3-4.6 km (7,000-15,000 ft) a.s.l, or as high as 3 km above the summit, and drifted NW. Hotspots were also identified in satellite images. Weather clouds obscured views on 7 July. Ash plumes rose to 3.7 km (12,000 ft) a.s.l. and drifted E on 8 July. The Alert Level remained at 3 (on a scale of 0-5), and the public was warned to stay outside of Danger Zone B, defined as a 3-km radius around the active vents in Lake Voui, and to stay away from drainages during heavy rains.
