The Decade Volcanoes are 16 volcanoes identified by the International Association of Volcanology and Chemistry of the Earth's Interior (IAVCEI) as being worthy of particular study in light of their history of large, destructive eruptions and proximity to densely populated areas. The Decade Volcanoes project encourages studies and public-awareness activities at these …

Sakurajima (Japanese: 桜島, literally "Cherry Blossom Island") is an active stratovolcano, formerly an island and now a peninsula, in Kagoshima Prefecture in Kyushu, Japan. The lava flows of the 1914 eruption connected it with the Ōsumi Peninsula. It is the most active volcano in Japan. As of April 2021, the volcanic activity still continues, dropping volcanic ash on the …

Taal Volcano (IPA: ; Tagalog: Bulkang Taal) is a large caldera filled by Taal Lake in the Philippines. Located in the province of Batangas, the volcano is second of the most active volcanoes in the country, with 38 recorded historical eruptions, all of which were concentrated on Volcano Island, near the middle of Taal Lake. The caldera was formed by prehistoric eruptions …

A stratovolcano, also known as a composite volcano, is a conical volcano built up by many layers (strata) of hardened lava and tephra. Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile with a summit crater and periodic intervals of explosive eruptions and effusive eruptions, although some have collapsed summit craters called calderas.

Terminology. The term "supervolcano" was first used in a volcanic context in 1949. Its origins lie in an early 20th-century scientific debate about the geological history and features of the Three Sisters volcanic region of Oregon in the United States. In 1925, Edwin T. Hodge suggested that a very large volcano, which he named Mount Multnomah, had existed in that region.

A volcano is a rupture 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.. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater.For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has …

These volcanoes filled up slowly over time, with eruptions creating layers on top of layers. Unlike shield volcanoes, lava dome volcanoes are created by small masses of lava that are too thick to flow very far down the slope. They commonly occur within the creators of large composite volcanoes. The dome grows from lava expanding within the volcano.

The Territory of Heard Island and McDonald Islands (HIMI) is an Australian external territory comprising a volcanic group of mostly barren Antarctic islands, about two-thirds of the way from Madagascar to Antarctica.The group's overall size is 372 km 2 (144 sq mi) in area and it has 101.9 km (63 mi) of coastline. Discovered in the mid-19th century, the islands lie on the Kerguelen …

The Republic of China (ROC), between 1912 and 1949, was a sovereign state recognised as the official designation of China when it was based on Mainland China, prior to the relocation of its central government to Taiwan as a result of the Chinese Civil War.At a population of 541 million in 1949, it was the world's most populous country.Covering 11.4 million square kilometres (4.4 …

Volcanism, vulcanism or volcanicity is the phenomenon of eruption of molten rock onto the surface of the Earth or a solid-surface planet or moon, where lava, pyroclastics, and volcanic gases erupt through a break in the surface called a vent. It includes all phenomena resulting from and causing magma within the crust or mantle of the body, to rise through the crust and form …
