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.

Copahue (Chile-Argentina), Southern Andes Volcano Observatory

Volcanic activity report for Copahue (Chile-Argentina), 2 October-8 October 2019

OVDAS-SERNAGEOMIN and ONEMI reported that during 2-7 October a webcam at Copahue recorded white and gray emissions rising as high as 300 m above the El Agrio Crater rim and drifting ENE, SE, and SSE. By 7 October the number and intensity of seismic events detected at Copahue had decreased to low levels. The volcano Alert Level was lowered to Yellow (second lowest level on a four-color scale). ONEMI maintained the Yellow Alert (the middle level on a three-color scale) for residents, and stated that the public should stay at least 1 km away from El Agrio Crater.

Ulawun (Papua New Guinea),

Volcanic activity report for Ulawun (Papua New Guinea), 2 October-8 October 2019

RVO reported that the fissure eruption on Ulawun?s WSW flank had ceased by 4 October, producing only diffuse white-to-gray steam plumes with a blueish tinge from the main coalesced vent. Weak incandescence from the vent was visible at night on 5 October. The lava-flow rate slowed to 3-5 m a day, likely because it was no longer being fed. RSAM decreased to 1,000 units; regular small high-frequency events were recorded during 4-7 October. RVO recommended that the Alert Level be reduced to Stage 2.

Volcanic activity report for Fuego (Guatemala), 2 October-8 October 2019

INSIVUMEH reported that there were 10-18 explosions per hour recorded at Fuego during 2-8 October, generating ash plumes that rose as high as 1.1 km above the crater rim and drifted 10-25 km S, SW, W, and NW.

Explosions sometimes produced shock waves that rattled houses in nearby communities. Incandescent material was ejected 200-400 m high and caused avalanches of material that occasionally traveled long distances (reaching vegetated areas) down the Seca (W), Taniluyá (SW), Ceniza (SSW), Trinidad (S), El Jute (SE), Las Lajas (SE), and Honda ravines.

Die Daten stellt die Smithsonian Institution im wöchentlich aktualisierten USGS Weekly Volcanic Activity Report zur Verfügung.

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.
