Increased eruptive activity at Cotopaxi – one of the world’s most dangerous volcanoes, Ecuador
Activity at Ecuador’s Cotopaxi — one of the world’s most dangerous volcanoes — increased during the afternoon hours of November 25, 2022, when the seismic network started detecting tremors associated with strong gas and vapor emissions. Minor eruptive activity was observed on October 21, 2022, prompting IGEPN to raise the Alert Level to Yellow (2 of 4).
After an increase in seismicity since mid-April 2015, Cotopaxi finally erupted on August 14, 2015, for the first time since 1940. Volcanic ash reached an estimated altitude of 15.2 km (50 000 feet) a.s.l. by the end of the UTC day. Highways, homes and cars near the volcano were coated in ash as a result
The last significant eruption of Cotopaxi took place in 1904
Cotopaxi is an active stratovolcano in the Andes Mountains, located about 50 km (31 miles) south of the capital Quito, Ecuador
This is one of the world’s highest volcanoes, reaching a height of 5 897 m (19 347 feet)
It is considered one of the world’s most dangerous volcanoes due to a glacial cover that makes it prone to fast-moving volcanic rock and mud flows, or lahars, and its proximity to a heavily populated area
Constant volcanic ash and gas emissions were reported by Washington VAAC early on November 26, with plumes rising up to 6.7 km (22 000 feet) above sea level at 00:50 UTC.1
A new volcanic ash emission to 6.7 km a.s.l. was reported at 10:00 UTC followed by yet another at 17:20 UTC — this time to 7.9 km (26 000 feet) a.s.l., lasting several hours and reaching a distance of about 85 km (52.8 miles) N-NW of the summit.
Ashfall has been reported in districts of El Pedregal, Tambillo, Guamaní, Amaguańa, Chillogallo, Quitumbe, Solanda, Lloa, Conocoto, Wholesale Market, Villaflora, and Rumipamba.
Authorities advised people to avoid the outside environment and to close their doors and windows tightly during ashfall. People leaving that must leave their homes are advised to wear appropriate clothes — long pants, gloves, shoes, long-sleeved shirts, hats, and facemasks.
