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.

Fuego (Guatemala), INSIVUMEH, Guatemala	Volcanic activity report for Fuego (Guatemala), 18 March-24 March 2020 On 16 March INSIVUMEH reported an increased number of avalanches at Fuego, traveling down the Ceniza (SSW), Trinidad (S), and Las Lajas (SE) ravines. A 600-m-long lava flow advanced down the Trinidad drainage. Weak explosive activity accompanied lava effusion. There were 4-12 explosions per hour recorded at Fuego during 17-24 March, generating ash plumes that rose as high as 1.1 km above the crater rim and generally drifted 10-22 km S, SW, and W.

Explosions sometimes produced shock waves that rattled nearby houses and were felt in communities within a 25-km radius. Incandescent material was ejected 100-400 m high and caused avalanches of material that occasionally traveled long distances (reaching vegetated areas) down the Seca (W), Taniluyá (SW), Ceniza, Trinidad, Honda, and Las Lajas ravines. Lava flows of variable lengths (400-1,000 m) descended the Trinidad and Ceniza ravines each day but were inactive by the evening of 23 March.	Ongoing

An explosion at 2210 on 17 March ejected incandescent material onto the flanks and produced an ash plume that rose 1.2 km above the crater rim and drifted SE. Minor ashfall was reported in the municipalities of Tetela del Volcán (20 km SW), San Andrés and Hueyapan (16 km SW), and Ocuituco (24 km SW) during 17-18 March.

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.
