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), 29 July-4 August 2020

INSIVUMEH reported that at 2050 on 29 July lahars descended the Las Lajas and El Jute drainages on Fuego?s SE flanks. There were 6-13 explosions per hour recorded during 29 July-4 August, generating ash plumes as high as 1.1 km above the crater rim that generally drifted 15-20 km NW, W, and SW. Shock waves rattled buildings within a 20-km radius, particularly in areas on the S flank. Incandescent material ejected 100-350 m high caused avalanches of blocks in the Ceniza (SSW), Seca (W), Trinidad (S), Taniluyá (SW), Las Lajas, and Honda drainages; avalanches sometimes reached vegetated areas. Ashfall was reported in several areas downwind including Morelia (9 km SW), Panimaché I and II (8 km SW), Finca Palo Verde, San Pedro Yepocapa (8 km NW), and Sangre de Cristo (8 km WSW).

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.
