Augustine Volcano (Alaska) during its eruptive phase on January 24, 2006. A volcano is commonly defined as a vent or fissure in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface.
Mount Yasur is a volcano on Tanna Island, Vanuatu, 361 m (1,184 ft) high above sea level, [2] on the coast near Sulphur Bay, northeast of the taller Mount Tukosmera, which was active in the Pleistocene. It has a largely unvegetated pyroclastic cone with a nearly circular summit crater 400 m in diameter. [1]
The eruption of Tambora occurred near the end of the Little Ice Age, exacerbating the background global cooling of the period. [14] This period also occurred during the Dalton Minimum, a period of relatively low solar activity from 1790 to 1830. May 1816 had the lowest Wolf number (0.1) to date since records on solar activity began. It is not ...
The volcano has been relatively quiet during the 21st century, with only a handful of small magnitude earthquakes and no demonstrable ground deformation. Although geophysically quiet, periodic geochemical surveys indicate that volcanic gas emanates from a fumarole at the summit of Mount Shasta from a deep-seated reservoir of partly molten rock.
Scientists are tracking changes at the giant supervolcano that lies under Yellowstone National Park, but they say there's no need to worry at the moment. “The western part of the Yellowstone ...
The Kilauea volcano inside of the Hawaii Volcanoes National Park is currently erupting in a remote and closed area of the park.. According to the Hawaiian Volcano Observatory, the eruption started ...
Inside the crater of Vesuvius. A 2006 study by Zanella, Gurioli, Pareschi, and Lanza used the magnetic characteristics of over 200 samples of lithic, roof-tile, and plaster fragments collected from pyroclastic deposits in and around Pompeii to estimate the equilibrium temperatures of the deposits. [22]
The volcano became quiescent at the end of the 13th century, and in the following years, it again became covered with gardens and vineyards as old. Even the inside of the crater was moderately filled with shrubbery. Vesuvius entered a new phase in December 1631, when a major eruption buried many villages under lava flows, killing around 3,000 ...
