Quilotoa volcano is a small 3 km wide caldera about 80 km SSW of Quito. It is the westernmost of Ecuador's Andean volcanoes. The caldera is the truncated remnant of a dacitic stratovolcano. It has steep inner walls which rise 400 m above the surface of a 240 m deep lake.
The only certain historical eruption of Quilotoa volcano occurred in 1280 and was one of the largest explosive eruptions in the world during the past 1000 years.
Geologic studies have shown evidence that Quilotoa has produced at least 8 large explosive eruptions during the past 200,000 years at intervals of 10,000-14,000 years.
Reports of historical eruptions from the caldera lake are not certain. At present, Quilotoa volcano has fumaroles on the lake floor and hot springs on the eastern flank.
