Cotopaxi (Spanish pronunciation: [kotoˈpaksi]) is an active stratovolcano in the Andes Mountains, located near Latacunga city of Cotopaxi Province, about 50 km (31 mi) south of Quito, and 31 km (19 mi) northeast of the city of Latacunga, Ecuador. [1] It is the second highest summit in Ecuador (after Chimborazo), reaching a height of 5,897 m ...
The two most recent eruptions of Vesuvius (1875–1906 and 1913–1944) each lasted more than 30 years. [25] Vesuvius is still regarded as an active volcano, although its current activity produces little more than sulfur-rich steam from vents at the bottom and walls of the crater. Layers of lava, ash, scoria and pumice make up the volcanic peak.
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 ...
Mount St. Helens (known as Lawetlat'la to the indigenous Cowlitz people, and Loowit or Louwala-Clough to the Klickitat) is an active stratovolcano located in Skamania County, Washington, [ 1 ] in the Pacific Northwest region of the United States. It lies 52 miles (83 km) northeast of Portland, Oregon, [ 2 ] and 98 miles (158 km) south of ...
The most recent recorded volcanic activity was between 1820 and 1854, but many eyewitnesses reported eruptive activity in 1858, 1870, 1879, 1882, and 1894 as well. [45] Additionally, the Smithsonian Institution's volcanism project records the last volcanic eruption as 1450 CE. [46] The volcano has had a VEI of 2, 3, and 4 at least nine times. [47]
Lascar is a stratovolcano in Chile within the Central Volcanic Zone of the Andes, a volcanic arc that spans Peru, Bolivia, Argentina and Chile. It is the most active volcano in the region, with records of eruptions going back to 1848. It is composed of two separate cones with several summit craters.
The volcano rises above the jungles of the western Amazon basin and the flanks are densely clad in forests. The volcano has a caldera that is 4 km (2.5 mi) across; there is a wide gap in the caldera wall to the east, formed by a collapse of the structure. There is an unvegetated stratovolcano rising about 1,300 m (4,265 ft) from inside the ...
An active volcano is a volcano that has erupted during the Holocene (the current geologic epoch that began approximately 11,700 years ago), is currently erupting, or has the potential to erupt in the future. [1] A volcano that is not currently erupting but could erupt in the future is known as a dormant volcano. [1]
