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:
Ioto (Japan) - Report for 3 September-9 September 2025 - NEW
Datum: Wed, 10 Sep 2025 04:10:41 -0400
Beschreibung:
The Japan Meteorological Agency (JMA) reported that an eruption at Ioto (Iwo-jima) began at around 1914 on 1 September from a submarine vent off the W coast of the island. An eruption plume rose about 1 km above the surface of the water and had darker- and lighter-colored components. The eruption was ongoing at least through the next day; a webcam image captured at 0730 on 2 September showed a Surtseyan ejection of dark material above the water?s surface and a white steam-and-gas plume drifting downwind. The Japan Coast Guard reported bubbling water around the vents on 14 August, and JMA noted that both seismicity and inflation increased on 30 August. The last eruption occurred in February.

Kanlaon (Philippines) - Report for 3 September-9 September 2025 - NEW
Datum: Wed, 10 Sep 2025 04:10:41 -0400
Beschreibung:
The Philippine Institute of Volcanology and Seismology (PHIVOLCS) reported continuing unrest and an ash emission at Kanlaon during 2-10 September. The seismic network recorded 0-7 daily volcanic earthquakes and daily sulfur dioxide emissions ranged from 762 to 1,922 tonnes per day. Gas-and-steam emissions of variable densities rose 75-700 m above the crater rim and drifted N, NW, and WSW. A period of diffuse ash emissions began at 1725 on 8 September and lasted about 55 minutes, producing low ash plumes that drifted WSW. At 0510 on 10 September an ash plume rose 600 m above the crater rim. The Alert Level remained at 2 (on a scale of 0-5); the public was warned to stay out of the 4-km-radius Permanent Danger Zone (PDZ) and pilots were advised to avoid flying close to the summit.

Karymsky (Russia) - Report for 3 September-9 September 2025 - NEW
Datum: Wed, 10 Sep 2025 04:10:41 -0400
Beschreibung:
The Kamchatkan Volcanic Eruption Response Team (KVERT) reported that moderate activity continued at Karymsky during 28 August-4 September. A daily weak thermal anomaly was identified in satellite images. The Aviation Color Code remained at Orange (the third level on a four-color scale). Dates and times are provided in Coordinated Universal Time (UTC); specific events are indicated in local time where specified.

Lokon-Empung (Indonesia) - Report for 3 September-9 September 2025 - NEW
Datum: Wed, 10 Sep 2025 04:10:41 -0400
Beschreibung:
The Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG) reported continuing unrest at Lokon-Empung during 3-9 September. Seismicity continued to be elevated. Daily white steam-and-gas plumes rose as high as 100 m above the Tompaluan Crater rim and drifted in multiple directions. The plumes were characterized as white and gray on 4 September. According to news articles and PVMBG incandescence at the crater was visible in webcam images during 4-9 September. The Alert Level remained at 3 (on a scale of 1-4) and the public was warned to stay 2.5 km away from Tompaluan Crater.

Whakaari/White Island (New Zealand) - Report for 3 September-9 September 2025 - NEW
Datum: Wed, 10 Sep 2025 04:10:41 -0400
Beschreibung:
GeoNet conducted an overflight at Whakaari/White Island a few days after ash plumes were observed in webcam views. During an overflight on 3 September scientists observed no ash in the steam-and-gas plumes rising from the active vents. Thin ashfall deposits from a brief eruption on 28 August were present on the island, though the active vent area was unchanged. Temperatures at the vents were around 164 degrees Celsius which was typical during periods of unrest. Measurements collected during overflights and from satellite data confirmed that gas output was steady and at levels consistent with minor activity. An area called Fumarole 0 on the S side of the main crater had dried out and an inclined vent was newly active. Several vents were active in the Fumarole 13/14 area on the N side of the main crater. The Volcanic Alert Level remained at 2 (on a scale of 0-5) and the Aviation Color Code remained at Yellow (the second lowest level on a four-color scale).

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.
