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:
Kirishimayama (Japan) - Report for 18 June-24 June 2025 - NEW
Datum: Wed, 25 Jun 2025 03:31:06 -0400
Beschreibung:
The Japan Meteorological Agency (JMA) reported that an eruption occurred at Shinmoedake (Shinmoe peak, a stratovolcano of the Kirishimayama volcano group) on 22 June, the first eruption since 27 June 2018. The number of volcanic earthquakes with epicenters directly beneath Shinmoedake had been fluctuating since late October 2024 but began to increase starting around 13 June. Another increase occurred at around 2100 on 21 June, and volcanic tremor increased on 22 June. An eruption detected during 1637-1755 on 22 June produced an ash plume that rose 500 m above the crater rim and drifted E. Ashfall was confirmed in a wide area to the NE that included Takaharu Town, Kobayashi City, Miyazaki City, Kunitomi Town, Saito City, and Shintomi Town in Miyazaki Prefecture. A large amount of ashfall in Hirohara, Takaharu-cho, Miyazaki Prefecture obscured the white lines on the roadway. Sulfur dioxide emissions averaged 4,000 tons per day on 23 June; no emissions were detected on 15 May during the last measurement. On 23 June the Alert Level was raised to 3 (on a 5-level scale) and the public was warned to exercise caution within 3 km from Shinmoedake Crater.

Kuchinoerabujima (Japan) - Report for 18 June-24 June 2025 - NEW
Datum: Wed, 25 Jun 2025 03:31:06 -0400
Beschreibung:
The Japan Meteorological Agency (JMA) reported that the number of shallow volcanic earthquakes increased beneath an area near Kuchinoerabujima?s Furudake Crater in April and continued to increase. Sulfur dioxide emissions were low, averaging 20-80 tons per day since April, and there were days in April where the emissions were below detectable limits. Deformation data indicated ongoing inflation. Volcanic earthquakes with somewhat large amplitudes were occasionally recorded in May by the seismic network. There were many (135) volcanic earthquakes recorded during 2-11 June. No changes to geothermal areas located in and around both Shindake and Furudake craters were observed during a field survey conducted on 11 June. The Alert Level was raised to 3 (on a scale of 1-5) at 2100 on 11 June; the public was warned that ejected blocks may land within 2 km of both craters, and pyroclastic flows may affect areas between Shindake Crater and the coast.

Lewotobi (Indonesia) - Report for 18 June-24 June 2025 - NEW
Datum: Wed, 25 Jun 2025 03:31:06 -0400
Beschreibung:
The Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG) reported that eruptive activity continued at Lewotobi Laki-laki during 18-25 June, after the explosive eruption on 17 June. At 0318 and 0641 on 18 June ash plumes rose 1 km above the summit and drifted N and NE. Visual observations of eruptive events recorded at 1229 and 2212 later that day, and at 0922 and 1008 on 19 June, were obscured by weather conditions; incandescence at the summit was visible in a webcam image at 2223 on 18 June. Dense gray ash plumes rose as high as 2 km above the summit and drifted S and SW at 2213 and 2231 on 20 June and at 0014 and 0024 on 21 June. Webcam images taken near midnight showed incandescent material being ejected above the summit and onto the upper flanks. An eruptive event was recorded at 1440 on 23 June but weather conditions again obscured views. According to news reports the number of evacuees totaled 4,954 on 19 June and 4,007 as of 21 June. The Alert Level remained at 4 (on a scale of 1-4) and the public was warned to stay 7 km away from the center of Laki-laki and 8 km in a semicircle clockwise from the SW to the NE.

Miyakejima (Japan) - Report for 18 June-24 June 2025 - NEW
Datum: Wed, 25 Jun 2025 03:31:06 -0400
Beschreibung:
The Japan Meteorological Agency (JMA) reported that the number of small volcanic earthquakes at Miyakejima decreased after a peak on 17 June that led to an Alert Level change. On 17 June the number of small volcanic earthquakes with epicenters directly below the summit crater totaled 59, and uplift near the summit was detected in tiltmeter data. During 18-23 June the number of daily earthquakes decreased to 0-4 earthquakes per day and no changes in tilt were detected after 18 June. The Alert Level remained at 2 (on a 5-level scale) and the public was warned to be cautious in areas inside the Oyama Ring Road.

Aira (Japan) - Report for 18 June-24 June 2025
Datum: Wed, 25 Jun 2025 03:31:06 -0400
Beschreibung:
The Japan Meteorological Agency (JMA) reported ongoing eruptive activity at Minamidake Crater (Aira Caldera?s Sakurajima volcano) during 16-23 June. One small eruptive event was recorded on 20 June. Weather clouds obscured views during 21-23 June. 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.

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.
