Reventador is an active stratovolcano which lies in the eastern Andes of Ecuador. It lies in a remote area of the national park of the same name, which is Spanish for 'exploder' or 'ripper'. Since 1541 it has erupted over 25 times, although its isolated location means that many of its eruptions have gone unreported. Its most recent eruption was in 2009, but the largest historical eruption occurred in 2002. During that eruption the plume from the volcano reached a height of 17 km and pyroclastic flows went up to 7 km from the cone.
On March 30, 2007, the mountain spewed ash again. The ash reached a height of about two miles (3 km, 11,000 ft). No injuries or damages have been reported.
