How long did the Chaitén volcano last?

On May 2, 2008, Chile’s Chaitén volcano erupted with an ash column that rose to about 17 km (10 mi) and lasted for 6 hours. Eruptive activity continued from May 2nd to May 8th with nearly continuous ash emission and intermittent large explosions.

What type of volcano is the Chaitén volcano?

caldera volcano
Chaitén is a caldera volcano formed when the magma chamber beneath a volcano completely empties during an eruption, causing the summit to collapse into it. The collapse creates a circular depression. Prior to its May 2008 eruption, the volcano had been dormant for more than 9,000 years.

Eventually, hot blocks of lava break away from the dome, triggering a fast-moving avalanche of hot volcanic ash, gas, and lava, called a pyroclastic flow.
