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:
Apaneca Range (El Salvador) - Report for 9 July-15 July 2025 - NEW
Datum: Wed, 16 Jul 2025 04:49:54 -0400
Beschreibung:
According to the Universidad de El Salvador a hydrothermal explosion occurred at Agua Shuca, a fumarolic field and lake (roughly 30 x 60 m) in the SW part of the Ahuachapán Geothermal Field in the Apaneca Range, on 10 July. Video of the event showed steam-and-gas plumes expanding from the lake area, ejections of boiling sediment and water, and waves of muddy water flowing over the surrounding land; a few people were seen running from the area, with one person taking shelter behind a wall. A team from the Universidad de El Salvador traveled to the area the next day to assess the event and the impacts, to take measurements, and to provide information to the nearby residents. The explosion created a crater about 70 m in diameter and 20 m deep. Photos indicated that mud and water were ejected mainly to the SE, covering an extending beyond a road, but deposits were seen around the margins of the lake in most directions. Gas emissions were low, suggesting that activity had returned to baseline levels; Agua Shuca does not have a monitoring network.

Erta Ale (Ethiopia) - Report for 9 July-15 July 2025 - NEW
Datum: Wed, 16 Jul 2025 04:49:54 -0400
Beschreibung:
Eruptive activity at Erta Ale continued during July based on satellite data and field observations. Small thermal anomalies at both the N and S pit craters were visible in periodic satellite image views on 1, 6, 8, and 11 July. On 15 July a dense black plume rising from an unstated area was filmed by a local observer and was thought to have originated from a collapse of a portion of crust covering a lava lake. A post on social media showed pictures of the plumes and stated that the plumes sank to the ground and spread out over an area of 15 km. Plumes were visible on 16 July.

Kirishimayama (Japan) - Report for 9 July-15 July 2025 - NEW
Datum: Wed, 16 Jul 2025 04:49:54 -0400
Beschreibung:
The Japan Meteorological Agency (JMA) reported that eruptive activity continued at Shinmoedake (Shinmoe peak, a stratovolcano of the Kirishimayama volcano group) during 10-16 July. The number of volcanic earthquakes with epicenters directly beneath Shinmoedake had been fluctuating since late October 2024; volcanic tremor was occasionally detected. Eruptive activity occurred intermittently with grayish-white plumes rising as high as 400 m above the crater rim. On 15 July sulfur dioxide emissions were high, averaging 1,600 tons per day. The Alert Level remained at 3 (on a 5-level scale) and the public was warned to exercise caution within 3 km from Shinmoedake Crater.

Lewotobi (Indonesia) - Report for 9 July-15 July 2025 - NEW
Datum: Wed, 16 Jul 2025 04:49:54 -0400
Beschreibung:
The Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG) reported that eruptive activity continued at Lewotobi Laki-laki during 8-15 July. Avalanches of material were occasionally detected during the week but not observed. Dense gray ash plumes rose 1.2-4 km above the summit and drifted W and NW. Summit incandescence was visible on 10 July. At 1410 on 11 July a dense gray ash plume rose 4 km above the summit and drifted W and NW. Eruptive events were detected on 9 and 14 July, but weather clouds prevented visual observations. The Alert Level remained at 4 (on a scale of 1-4) and on 25 June the exclusion zone was reduced to 6 km from the center of Laki-laki and 7 km in a semicircle clockwise from the SW to the NE.

Lewotolok (Indonesia) - Report for 9 July-15 July 2025 - NEW
Datum: Wed, 16 Jul 2025 04:49:54 -0400
Beschreibung:
The Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG) reported that an eruption at Lewotolok was ongoing during 2-15 July. White plumes on 9 and 12 July rose 100 m above the summit and drifted W and NW. Gray or white-to-gray ash plumes rose 200-400 m above the summit of the cone and drifted W during 10-11 and 13-15 July. Clear nighttime webcam images showed incandescent material being ejected above the cone. The Alert Level remained at 3 (on a scale of 1-4) and the public was warned to stay 3 km away from the summit.

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.
