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), 20 May-26 May 2020 INSIVUMEH reported that in the evening on 20 May a new lava flow at Fuego traveled 300 m down the Ceniza (SSW) drainage. The crater was incandescent and gas emissions were constant; avalanches descended the flanks 1 km and reached vegetated areas. Explosions produced shock waves and ash plumes that rose just over 1 km above the summit. Lahars descended the Las Lajas ravine on the E flank 1650 on 21 May and the Ceniza drainage on the SW flank. There were 5-12 explosions per hour recorded during 22-26 May, generating ash plumes as high as 1.1 km above the crater rim that generally drifted 10-15 km in multiple directions. Shock waves rattled buildings within a 20-km radius, particularly in areas on the S flank. Incandescent material was ejected 100-300 m high and caused avalanches of blocks in the Ceniza, Seca (W), Trinidad (S), Las Lajas, and Honda drainages. Ashfall was reported in several areas downwind including Santa Sofía (12 km SW), Morelia (9 km SW), Panimaché I and II (8 km SW), Ciudad Vieja (13.5 km NE), San Miguel Dueñas (10 km NE), and Antigua Guatemala (18 km NE). Lava flows in the Ceniza drainage varied in length between 150 and 400 m long.	Ongoing
Ibu (Indonesia), Centre of Volcanology and Geological Hazard Mitigation	Volcanic activity report for Ibu (Indonesia), 20 May-26 May 2020 The Darwin VAAC reported that on 20 May an ash plume from Ibu rose to 1.8 km (6,000 ft) a.s.l., or 500 m above the crater rim, based on information from PVMBG. Weather clouds prevented satellite views of the event. The Alert Level remained at 2 (on a scale of 1-4), and the public was warned to stay at least 2 km away from the active crater, and 3.5 km away on the N side.	Ongoing
Klyuchevskoy (Russia), Kamchatka Volcanic Eruption Response Team	Volcanic activity report for Klyuchevskoy (Russia), 20 May-26 May 2020 KVERT reported that Strombolian activity at Klyuchevskoy was visible during 15-22 May along with a bright thermal anomaly identified in satellite images. A lava flow continued to advance down the Apakhonchich drainage on the SE flank. Gas-and-steam plumes with some ash drifted 100 km NW, E, and SE during 15-17 and 21 May. The Aviation Color Code remained at Orange.	Ongoing
Pacaya (Guatemala), INSIVUMEH, Guatemala	Volcanic activity report for Pacaya (Guatemala), 20 May-26 May 2020 INSIVUMEH reported that during 19-26 May Strombolian explosions at Pacaya?s Mackenney Crater ejected material as high as 100 m above the crater rim. Active lava flows were 200 m long on the NW flank during 21-22 May and 300 m long on the NE flank during 25-26 May.	Ongoing
Popocatepetl (Mexico), CENAPRED, México	Volcanic activity report for Popocatepetl (Mexico), 20 May-26 May 2020 CENAPRED reported that each day during 20-26 May there were 90-251 steam-and-gas emissions from Popocatépetl, some of which contained minor amounts of ash. The plumes drifted mainly E and SE. An explosion at 0302 on 21 May ejected incandescent material onto the flanks. The Alert Level remained at Yellow, Phase Two (middle level on a three-color scale).	Ongoing
Rincon de la Vieja (Costa Rica), OVSICORI-UNA, Costa Rica	Volcanic activity report for Rincon de la Vieja (Costa Rica), 20 May-26 May 2020 OVSICORI-UNA reported that periodic phreatic explosions at Rincón de la Vieja continued to be recorded by the seismic network and webcams during 20-26 May; most plumes rose no higher than 500 m above the crater rim. Some of the events were not visually confirmed by webcams because of weather conditions or darkness. A small ash eruption at 0537 on 21 May produced a plume that rose 1 km above the crater rim and contained less water vapor than plumes from eruptive events in the past weeks. Plumes from eruptive events at 1624 on 22 May and 0608 on 24 May rose 1 km above the rim. An event at 0325 on 25 May was heard by residents to the N but was no visually confirmed due to darkness. Later that day, in the early evening, an hour-long sequence of eruptions produced gas-and-steam plumes and ejected tephra no higher than the crater rim (except for an event at 1738).	Ongoing
Santa Maria (Guatemala), INSIVUMEH, Guatemala	Volcanic activity report for Santa Maria (Guatemala), 20 May-26 May 2020 INSIVUMEH reported that during 19-26 May explosions at Santa María's Santiaguito lava-dome complex generated ash plumes that rose 700-1,000 m above the crater and drifted as far as 1 km NW, W, and SW. Avalanches of blocks descended the S, SE, and SW flanks of Caliente cone. Local ashfall around the volcano was sometimes reported.	Ongoing
Semeru (Indonesia), Centre of Volcanology and Geological Hazard Mitigation	Volcanic activity report for Semeru (Indonesia), 20 May-26 May 2020 PVMBG reported that the eruption at Semeru continued during 20-26 May, though sometimes foggy conditions prevented visual confirmation. Incandescent material from the ends of lava flows descended 400-700 m in the Kembar drainage (on the S flank) during 20-21 and 25-26 May, reaching a maximum distance of 1.2 km from the crater. Ash plumes rose 200-500 m above the crater and drifted S during 19-20 May and N during 24-25 May. White plumes rose 400 m and drifted NE, E, S, and W on 26 May. The Alert Level remained at 2 (on a scale of 1-4), and the public was reminded to stay outside of the general 1-km radius from the summit and 4 km on the SSE flank.	Ongoing

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.
