Tungurahua, a steep-sided stratovolcano that towers more than 3 km above its northern base, is one of Ecuador's most active volcanoes. Historical eruptions have frequently modified the morphology of the summit crater, which is now 300-m wide and 200-m deep. They have been accompanied by strong explosions and sometimes by pyroclastic flows and lava flows that reached populated areas at the volcano's base. The last major eruption began in 1916 and lasted until 1925.
