A stratovolcano, also known as a composite volcano, is a typically conical volcano built up by many alternating layers of hardened lava and tephra. [1] Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile with a summit crater and explosive eruptions. [2] Some have collapsed summit craters called calderas. [3]
Mount Katmai (Russian: Катмай) is a large active stratovolcano (composite volcano) on the Alaska Peninsula in southern Alaska, located within Katmai National Park and Preserve. It is about 6.3 miles (10 km) in diameter with a central lake-filled caldera about two by three miles (3.2 by 4.8 km) in size, formed during the Novarupta eruption ...
Glacier Peak or Dakobed (known in the Sauk-Suiattle dialect of the Lushootseed language as "Tda-ko-buh-ba" or "Takobia" [5]) is the most isolated of the five major stratovolcanoes (composite volcanoes) of the Cascade Volcanic Arc in the U.S state of Washington.
The National Institute of Geophysics and Volcanology (Italian: Istituto Nazionale di Geofisica e Vulcanologia, INGV) is a research institute for geophysics and volcanology in Italy. INGV is funded by the Italian Ministry of Education, Universities and Research . [ 1 ]
The name Huaynaputina, also spelled Huayna Putina, was given to the volcano after the 1600 eruption. [2] [3] According to one translation cited by the Peruvian Ministry of Foreign Trade and Tourism, Huayna means 'new', and Putina means 'fire-throwing mountain'; the full name is meant to suggest the aggressiveness of its volcanic activity and refers to the 1600 eruption being its first one.
The seamount is a submarine volcano, southwest of Molokaʻi. The submarine volcano used to be part of Maui Nui, a prehistoric island made from seven shield volcanoes. Koʻolau Range: Oʻahu <32,000 BP (possibly dormant) [n 3: 2.7 million [28]
It consists mainly of volcanic rocks that form the largest remnant of a major composite volcanic field that covered most of the southern Rocky Mountains in the Middle Tertiary geologic time. [1] There are approximately fifteen calderas known in the San Juan Volcanic Fields; however, it is possible that there are two or even three more in the ...
Aira caldera is one of the most active and hazardous calderas in the world. It is home to the Kirishima volcanoes, a group of active volcanoes at the north end of Aira caldera. One of these volcanoes, Shinmoedake, has produced two strong magmato-phreatic eruptions, separated by almost 300 years. Starting in December 2009, active diving and ...
