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.

Kilauea (United States), Hawaiian Volcano Observatory

Volcanic activity report for Kilauea (United States), 6 January-12 January 2021

HVO reported that lava effusion from vents on a cone on the inner NW wall of Kilauea?s Halema`uma`u Crater continued to feed a growing perched lava lake during 6-12 January. Lava flowed through a crusted channel into the lake during most of the week. A dome fountain of upwelled lava at the partially submerged inlet was 5 m tall early on 6 January. Dome fountaining had weakened early on 7 January, giving way to spattering at the top of the vent and the formation of a second cone. Dome fountaining was possibly visible again on 8 January. The lake was perched at least 1-2 m above its narrow edges, though late on 10 January the stagnant, eastern part of the lake had subsided and was 3-4 m shallower. Overall the lake had deepened just 2 m by 11 January, reaching 196 m, and the lake volume was estimated at more than 27 million cubic meters. An island of cooler, solidified lava and the 11 smaller islands were relatively stationary in the E part of the lake. The dimensions of the largest island remained unchanged (250 m long and 135 m wide), though on 8 January the W end was 9 m above the lake?s surface and the high point was 23 m above the lake, suggesting that the island was rising. Sulfur dioxide emissions were 2,700 and 2,300 tonnes/day on 7 and 10 January, respectively.

Merapi (Indonesia), Centre of Volcanology and Geological Hazard Mitigation

Volcanic activity report for Merapi (Indonesia), 6 January-12 January 2021

BPPTKG reported that a new lava dome, first observed on 4 January, continued to emerge just below Merapi?s SW rim during 5-12 January. Incandescent avalanches were observed 19 times during 4-7 January with material traveling as far as 800 m down the Krasak River drainage on the SW flank. At 0802 on 7 January a block-and-ash flow traveled down the upper part of the Krasak; the total distance was not observable due to weather clouds, though the seismic data suggested it was small and was not more than 1 km in length. The event also produced a 200-m-high ash plume. Similar events were recorded that same day at 1250, 1315, and 1402. Deformation continued; electronic Distance Measurement (EDM) data continued to measure a distance shortening between points in the NW at a rate of 15 cm per day. On 7 January BNPB noted that 1,342 residents were housed in evacuation centers. The Alert Level remained at 3 (on a scale of 1-4), and the public were warned to stay 5 km away from the summit.

Pelee (France), IPGP Observatoire Volcanologique de la Montagne Pelée

Volcanic activity report for Pelee (France), 6 January-12 January 2021

L'Observatoire Volcanologique et Sismologique de Martinique (OVSM) reported that seismicity related to volcanism has typically remained low at Pelée since 1980, when monitoring instrumentation was first installed, with a few dozen earthquakes recorded per year. Swarms were recorded in 1980, 1985-1986, 2007, and 2014, though the latter two swarms were associated with tectonic events. Volcanic seismicity appeared in April 2019 centered 4-5 km below the summit and deeper (more than 10 km below sea level). In addition, tremor-type signals were recorded during 8-9 November 2020, possibly signifying a reactivation of the hydrothermal system. The seismic data recorded since April 2019 represented an increase above baseline levels recorded during 1 January 2015 to April 2019. As a result of this activity OVSM raised the Alert Level to Yellow (the second lowest level on a four-color scale) on 4 December 2020. Seismicity remained above background levels during 18 December 2020-1 January 2021, with at least 14 volcano-tectonic earthquakes detected with magnitudes less than or equal to 1. Scientists did not observe fumarolic activity during an overflight on 29 December 2020. The number of high-frequency, volcano-tectonic earthquakes (M 1 or less) totaled 65 during 1-8 January. A significant number (249) of long-period earthquakes in a volcanic tremor-type signal were distributed over two periods, 0000-0200 on 3 January and between 2100 on 3 January and 0200 on 4 January. Two isolated, low-frequency, long-period signals were also recorded. The data suggested ongoing perturbation of the hydrothermal system.

Soufriere St. Vincent (Saint Vincent and the Grenadines), Seismic Research Unit, Univ. West Indies

Volcanic activity report for Soufriere St. Vincent (Saint Vincent and the Grenadines), 6 January-12 January 2021

University of the West Indies Seismic Research Centre (UWI-SRC) and National Emergency Management Organisation (NEMO) reported that the lava dome in Soufrière St. Vincent?s main crater that first formed on 27 December continued to grow during 6-12 January. Observations were made during a field visit on 5 January, during a helicopter overflight on 6 January, and based on 9 January drone video. During that time the dome grew and expanded to the W, produced small, hot rockfalls, had a blocky appearance, and continued to emit gasses and steam. Gas-and-steam plumes were also visible from Belmont Observatory. The Alert Level remained at Orange (the second highest level on a four-color scale).

Volcanic activity report for Suwanosejima (Japan), 6 January-12 January 2021

JMA reported that incandescence at Suwanosejima?s Ontake Crater was visible nightly during 4-11 January. Two explosions on 5 January produced ash plumes that rose 1.2 km above the crater rim and ejected bombs 400 m away from the crater. Two explosions during 9-10 January generated ash plumes that rose 1 km and again ejected bombs 400 m away. The Alert Level remained at 3 (on a 5-level scale).

Volcanic activity report for Aira (Japan), 6 January-12 January 2021

JMA reported that during 4-11 January incandescence from Minamidake Crater (at Aira Caldera?s Sakurajima volcano) was often visible nightly. The sulfur dioxide emission rate remained high and reached extremely high levels of 5,000 tons per day on 6 January. An explosion at 1642 on 4 January produced an ash plume that rose 1.8 km above the crater rim and merged into weather clouds. An explosion at 1133 on 11 January generated an ash plume that rose 1.3 km. The Alert Level remained at 3 (on a 5-level scale).

Pacaya (Guatemala), INSIVUMEH, Guatemala

Volcanic activity report for Pacaya (Guatemala), 6 January-12 January 2021

INSIVUMEH reported that the lava flow that began on 2 January from a vent on the SW flank, 200 m below Pacaya?s Mackenney Crater, formed 3-4 branches and was 400 m long by 6 January. Avalanches of material descended the W, SW, and S flanks. Strombolian explosions produced ash plumes that rose 100-150 m above the cone and drifted 10 km S and SW. Explosions on 7 January produced ash plumes that rose 300-500 m above the crater and ejected ballistics 300 m away from the crater. Explosions rattled structures in nearby villages. Two new lava flows emerged on the N flank at 0740; one traveled 50 m and the other 200 m. Active lava flows on the W and SW flanks were 550 m long. Overnight during 7-8 January a new lava flow on the SW flank descended 425 m. During 9-12 January Strombolian explosions continued to ejected material up to 300 m above the cone. The lava flow on the SW flank reached a length of 1.2 km on 9 January and 1.5 km by 10 January; it remained active through 12 January. Ash plumes drifted 10 km W during 10-11 January, and avalanches form the crater area descended the SW and S flanks.

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.
