The volcano's most recent eruptive episode began in 1994. Quiet periods of a few days have alternated with almost continuous Strombolian eruptions since then. Hot gases, rocks, and lava were released in an eruption in April 2008. Scientists monitoring the volcano warned people to stay out of a 3 km (1.9 mi) zone around the island. [12]
Víti geothermal lake at Askja Askja and Víti (in the foreground). Askja (ⓘ) is an active volcano situated in a remote part of the central highlands of Iceland.The name Askja refers to a complex of nested calderas within the surrounding Dyngjufjöll [ˈtiɲcʏˌfjœtl̥] mountains, which rise to 1,514 m (4,967 ft), askja meaning box or caldera in Icelandic.
A new island volcano rose above the waterline a few days later. The eruptions were initially of pumice and ash, and that island and the two islands that followed were quickly eroded away by the sea. Eventually, a fourth island, named Anak Krakatau (meaning "child of Krakatoa" in Indonesian), broke water in August 1930 and produced lava flows ...
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, ...
Volcanoes are usually mountains (sometimes islands, lakes, plateaus, calderas, seamounts or lava domes) that are formed when magma (liquid rock) wells up from inside the Earth. There are also analogous formations away from the Earth. Many volcanoes are categorized both as volcanoes and other landforms, such as mountains (if qualified).
Sangay (also known as Macas, Sanagay, or Sangai) [8] is an active stratovolcano in central Ecuador.It exhibits mostly strombolian activity. Geologically, Sangay marks the southern boundary of the Northern Volcanic Zone, and its position straddling two major pieces of crust accounts for its high level of activity.
Volcanoes, he said, were formed where the rays of the sun pierced the earth. The volcanoes of southern Italy attracted naturalists ever since the Renaissance led to the rediscovery of Classical descriptions of them by wtiters like Lucretius and Strabo. Vesuvius, Stromboli and Vulcano provided an opportunity to study the nature of volcanic ...
