A stratovolcano, also known as a composite volcano, is a conical volcano built up by many layers (strata) of hardened lava and tephra. [1] 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 ...
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. The process that forms volcanoes is called volcanism. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and because most of Earth ...
Mount Rainier (/ r eɪ ˈ n ɪər / ray-NEER), also known as Tahoma, is a large active stratovolcano in the Cascade Range of the Pacific Northwest in the United States. The mountain is located in Mount Rainier National Park about 59 miles (95 km) south-southeast of Seattle. [4]
Volcanic arc / belt. Central Mindanao Volcanic Arc. Last eruption. 1948–1953. Climbing. Easiest route. from Ardent Hot Springs. Mount Hibok-Hibok (also known as Catarman Volcano[3][4]) is a stratovolcano on Camiguin Island in the Philippines. [1] It is one of the active volcanoes in the country and part of the Pacific ring of fire.
Lava dome. In volcanology, a lava dome is a circular, mound-shaped protrusion resulting from the slow extrusion of viscous lava from a volcano. Dome-building eruptions are common, particularly in convergent plate boundary settings. [1] Around 6% of eruptions on Earth form lava domes. [1]
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 Central American Volcanic Arc (often abbreviated to CAVA) is a chain of volcanoes which extends parallel to the Pacific coastline of the Central American Isthmus, from Mexico to Panama. This volcanic arc, which has a length of 1,100 kilometers (680 mi) [1][2] is formed by an active subduction zone, with the Cocos Plate subducting underneath ...
Volcanic hazard. A schematic diagram shows some of the many ways volcanoes can cause problems for those nearby. A volcanic hazard is the probability a volcanic eruption or related geophysical event will occur in a given geographic area and within a specified window of time. The risk that can be associated with a volcanic hazard depends on the ...
