Gunung Tungurahua

Tungurahua

Stratovolkan · Ecuador · 5023 m

Snow-capped Tungurahua, seen from near the town of Baños on its northern flank, rises 3200 m above steep-walled canyons. Historical eruptions, separated by long reposes, have produced powerful explosions, sometimes accompanied by pyroclastic flows and lava flows. All historical eruptions have originated from the summit crater, and have typically lasted for several years. The largest historical eruptions took place in 1886, 1916, and 1918.

Ringkasan geologi

Tungurahua, a steep-sided andesitic-dacitic stratovolcano that towers more than 3 km above its northern base, is one of Ecuador's most active volcanoes. Three major edifices have been sequentially constructed since the mid-Pleistocene over a basement of metamorphic rocks. Tungurahua II was built within the past 14,000 years following the collapse of the initial edifice. Tungurahua II collapsed about 3,000 years ago and produced a large debris-avalanche deposit to the west. The modern glacier-capped stratovolcano (Tungurahua III) was constructed within the landslide scarp. Historical eruptions have all originated from the summit crater, accompanied by strong explosions and sometimes by pyroclastic flows and lava flows that reached populated areas at the volcano's base. Prior to a long-term eruption beginning in 1999 that caused the temporary evacuation of the city of Baños at the foot of the volcano, the last major eruption had occurred from 1916 to 1918, although minor activity continued until 1925.
