Eifel hotspot

The Eifel hotspot is a volcanic hotspot in Western Germany. The hotspot is thought to be the source of many recent volcanic formations in and around the Eifel mountain range, especially the volcanic field known as Volcanic Eifel.[1] Although the last eruption occurred around 10,000 years ago, the presence of escaping volcanic gases in the region indicates that it is still active, if only weakly.

Eifel

The Eifel (German: [ˈaɪfl̩] (listen); Luxembourgish: Äifel, pronounced [ˈæːɪ̯fəl]) is a low mountain range in western Germany and eastern Belgium. It occupies parts of southwestern North Rhine-Westphalia, northwestern Rhineland-Palatinate and the southern area of the German-speaking Community of Belgium.

The Eifel is part of the Rhenish Massif; within its northern portions lies the Eifel National Park.

Hotspot (geology)

In geology, the places known as hotspots or hot spots are volcanic regions thought to be fed by underlying mantle that is anomalously hot compared with the surrounding mantle. Their position on the Earth's surface is independent of tectonic plate boundaries. There are two hypotheses that attempt to explain their origins. One suggests that hotspots are due to mantle plumes that rise as thermal diapirs from the core–mantle boundary. The other hypothesis is that lithospheric extension permits the passive rising of melt from shallow depths. This hypothesis considers the term "hotspot" to be a misnomer, asserting that the mantle source beneath them is, in fact, not anomalously hot at all. Well-known examples include the Hawaii, Iceland and Yellowstone hotspots.

List of Quaternary volcanic eruptions

This article is a list of volcanic eruptions of approximately magnitude 6 or more on the Volcanic Explosivity Index (VEI) or equivalent sulfur dioxide emission during the Holocene, and Pleistocene eruptions of the Decade Volcanoes (Avachinsky-Koryaksky, Kamchatka; Colima, Trans-Mexican Volcanic Belt; Mount Etna, Sicily; Galeras, Andes, Northern Volcanic Zone; Mauna Loa, Hawaii; Mount Merapi, Central Java; Mount Nyiragongo, East African Rift; Mount Rainier, Washington; Sakurajima, Kagoshima Prefecture; Santamaria/ Santiaguito, Central America Volcanic Arc; Santorini, Cyclades; Taal Volcano, Luzon Volcanic Arc; Teide, Canary Islands; Ulawun, New Britain; Mount Unzen, Nagasaki Prefecture; Mount Vesuvius, Naples); Campania, Italy; South Aegean Volcanic Arc; Laguna de Bay, Luzon Volcanic Arc; Mount Pinatubo, Luzon Volcanic Arc; Toba, Sunda Arc; Mount Meager massif, Garibaldi Volcanic Belt; Yellowstone hotspot, Wyoming; and Taupo Volcanic Zone, greater than VEI 4.

The eruptions in the Holocene on the link: Holocene Volcanoes in Kamchatka were not added yet, but they are listed on the Peter L. Ward's supplemental table. Some of the eruptions are not listed on the Global Volcanism Program timetable as well, at least not as VEI 6. The timetables of Global Volcanism Program; Bristlecone pine tree-rings (Pinus longaeva, Pinus aristata, Pinus ponderosa, Pinus edulis, Pseudotsuga menziesii); the 4 ka Yamal Peninsula Siberian larch (Larix sibirica) chronology; the 7 ka Scots pine (Pinus sylvestris) chronology from Finnish Lapland; GISP2 ice core; GRIP ice core; Dye 3 ice core; Bipolar comparison; Antarctic ice core (Bunder and Cole-Dai, 2003); Antarctic ice core (Cole-Dai et al., 1997); Crête ice core, in central Greenland, benthic foraminifera in deep sea sediment cores (Lisiecki, Raymo 2005), do not agree with each other sometimes. The 536–547 AD dust-veil event might be an impact event.

List of large volcanic eruptions

This is a sortable summary of the pages Timeline of volcanism on Earth, List of Quaternary volcanic eruptions, and Large volume volcanic eruptions in the Basin and Range Province. Uncertainties as to dates and tephra volumes are not restated, and references are not repeated. Volcanic Explosivity Index (VEI) values for events in the Miocene epoch sometimes lack references. They are given as VEI-equivalent, as orientation of the erupted tephra volume. Please note that this is not a comprehensive list, and some events are missing from the table.

Timeline of volcanism on Earth

This timeline of volcanism on Earth is a list of major volcanic eruptions of approximately at least magnitude 6 on the Volcanic Explosivity Index (VEI) or equivalent sulfur dioxide emission around the Quaternary period (from 2.58 Mya to the present).

Some eruptions cooled the global climate—inducing a volcanic winter—depending on the amount of sulfur dioxide emitted and the magnitude of the eruption. Before the present Holocene epoch, the criteria are less strict because of scarce data availability, partly since later eruptions have destroyed the evidence. Only some eruptions before the Neogene period (from 23 Mya to 2.58 Mya) are listed. Known large eruptions after the Paleogene period (from 66 Mya to 23 Mya) are listed, especially those relating to the Yellowstone hotspot, the Santorini caldera, and the Taupo Volcanic Zone.

Active volcanoes such as Stromboli, Mount Etna and Kilauea do not appear on this list, but some back-arc basin volcanoes that generated calderas do appear. Some dangerous volcanoes in "populated areas" appear many times: so Santorini, six times and Yellowstone hotspot, twenty-one times. The Bismarck volcanic arc, New Britain, and the Taupo Volcanic Zone, New Zealand, appear often too.

In addition to the events listed below, are many examples of eruptions in the Holocene on the Kamchatka Peninsula, which are described in a supplemental table by Peter Ward.
