Vulkan-Monitor
In einer Tiefe ab 100 km, ist es zwischen 1000 und 1300 Grad Celsius heiß. Gestein beginnt zu schmelzen und sammelt sich in großen, tropfenförmigen Magmaherden in 2 bis 50 km Tiefe. Wenn der Druck zu groß wird, steigt das Magma über Spalten und Klüfte an die Oberfläche: Ein Vulkan entsteht.Augenblicklich aktive Vulkane:
Ambae (Vanuatu) - Report for 4 June-10 June 2026 - New Eruptive Activity
Datum: Thu, 11 Jun 2026 03:42:26 -0400
Beschreibung:
The Wellington Volcanic Ash Advisory Center (VAAC) reported that emissions of ash-and-gas plumes from Ambae were identified during 4-5 June using satellite and webcam images. The plumes rose 3 km (10,000 ft) a.s.l. and drifted S. 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.

Nevado de Longavi (Chile) - Report for 4 June-10 June 2026 - New Unrest
Datum: Thu, 11 Jun 2026 03:42:26 -0400
Beschreibung:
The Servicio Nacional de Geología y Minería (SERNAGEOMIN), Servicio Nacional de Prevención y Respuesta ante Desastres (SENAPRED), and the Servicio Geológico Minero Argentino (SEGEMAR) stated that seismicity at Nevado de Longaví gradually declined after a seismic swarm on 20 May. A few isolated seismic events were recorded during 21-31 May, with activity close to baseline levels. The Alert Level remained at Yellow (the second lowest level on a four-color scale) and SENAPRED maintained a ?Preventative Early Warning? for the communities of Longaví (53 km WNW), Linares (55 km NW), and Colbún (60 km NNW).

Titan Ridge (Papua New Guinea) - Report for 4 June-10 June 2026 - New Eruptive Activity
Datum: Thu, 11 Jun 2026 03:42:26 -0400
Beschreibung:
The Rabaul Volcano Observatory (RVO) reported that the eruption at Titan Ridge continued during 4-9 June. The number of hydroacoustic signals per day decreased during 4-8 June, followed by a minor increase on 9 June. A narrow but dense steam plume drifted about 50 km NW at low altitudes due to strong winds. A possible small intermittent plume may have risen from an area just to the SW of the main plume. Despite a reduction in the number of daily acoustic events, thermal anomalies around the plume area had intensified. Significant amounts of floating pumice, forming thick and extensive rafts, continued to wash up on the shores of the Admiralty Islands. According to a news article pumice rafts impacted the S coastline of Manus Island and made boat access difficult or impossible. An observer reported that one of the pumice rafts was about 3 km wide, 5 km long, and around 5 m deep. The rafts covered reefs and grasses, and caused the deaths of fish.

Aira (Japan) - Report for 4 June-10 June 2026 - Continuing Eruptive Activity
Datum: Thu, 11 Jun 2026 03:42:26 -0400
Beschreibung:
The Japan Meteorological Agency (JMA) reported ongoing eruptive activity at Minamidake Crater (Aira Caldera?s Sakurajima volcano) during 1-8 June. Sulfur dioxide emissions were high, averaging 2,900 tons per day on 3 June. Very small eruptive events were detected during 1-5 June. Continuous ash emissions during 0652-0755 on 7 June rose as high as 1.3 km above the crater rim and drifted SE and W. A news article stated that ash fell across Kagoshima City, though this was unconfirmed by JMA. An explosion later that day, at 1907, was recorded by the seismic network but not visually observed. An explosion at 2141 on 8 June generated an ash plume that rose 700 m above the crater rim and drifted SE and ejected large blocks 500-700 m from the crater. 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.

Dukono (Indonesia) - Report for 4 June-10 June 2026 - Continuing Eruptive Activity
Datum: Thu, 11 Jun 2026 03:42:26 -0400
Beschreibung:
The Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG) reported that eruptive activity at Dukono continued during 4-10 June. Daily white-to-gray or gray-to-black plumes rose 300-2,000 m above the summit and drifted N, NE, E, and NW. Faint rumbling was heard at the Dukono observation post (11 km N) on 6 June. The Alert Level remained at Level 2 (on a scale of 1-4) and the public was warned to stay 4 km away from the Malupang Warirang Crater.

In Deutschland gibt es momentan keine aktiven Vulkane. Der Vulkanismus in Deutschland in den verangengen Jahrentausenden bzw. Jahrmillionen wurde durch Hebung der Alpen verursacht. Dass dieser Prozess noch nicht abgeschlossen ist, zeigen kleinere Erdbeben vom Rheingraben bis zur Kölner Bucht. Die Vulkane, die es in Deutschland gibt spucken zwar zur Zeit keine Lava aus, aber es gibt in Deutschland an vielen Orten heiße Quellen. Diese Thermalquellen sind ein Zeichen dafür, dass Wasser im inneren der Erde erwärmt wird. Vulkanaktivitäten aus vergangenen Zeiten sieht man in Deutschland z.B. auch am Kaiserstuhl in der oberrheinischen Ebene und am Rand der Schwäbischen Alp.
