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". 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 began in 2008[3] and is ongoing as of April 13, 2021. The largest historical eruption occurred in 2002.[3] During that eruption, the plume from the volcano reached a height of 17 kilometres (11 mi) and pyroclastic flows proceeded to 7 kilometres (4.3 mi) from the cone.

Reventador is part of a chain of volcanoes in the Cordillera Real, much further east than the main volcanic axis of the region. The volcano rises above the jungles of the western Amazon basin and the flanks are densely clad in forests. The volcano has a caldera that is 4 km (2.5 mi) across; there is a wide gap in the caldera wall to the east, formed by a collapse of the structure. There is an unvegetated stratovolcano rising about 1,300 m (4,265 ft) from inside the caldera, and this is the main seat of current volcanic activity. The lavas are andesitic.[4]

On March 30, 2007, the mountain ejected ash again. The ash reached a height of about 2 miles (11,000 ft). No injuries or damage were reported.[5]

According to NOAA Aviation Weather, a Volcanic Ash Advisory was issued at 2017-10-18T 13:17:00Z for volcanic ash to 13,000 feet (3,962 m). Reventador is one of the most active volcanoes in Ecuador. In 2020, there were near daily emissions of clouds of ash rising one or two kilometres into the air, occasional crater incandescence, and frequent avalanches of incandescent blocks.[5]
