Volcán Sangay

Sangay

Estratovolcán · Ecuador · 5286 m

The isolated Sangay volcano towers above tropical jungles east of the Andean crest. Seen here from the NE, it is one of Ecuador's most active volcanoes and has been in frequent eruption during the past several centuries. The steep-sided, glacier-covered volcano has been constructed within the older Verdeloma somma to the south. Historical eruptions were first reported in 1628. More-or-less continuous eruptions took place from 1728 until 1916, and again from 1934 until the present.

Resumen geológico

The isolated Sangay volcano, located east of the Andean crest, is the southernmost of Ecuador's volcanoes and its most active. The steep-sided, glacier-covered, dominantly andesitic volcano grew within the open calderas of two previous edifices which were destroyed by collapse to the east, producing large debris avalanches that reached the Amazonian lowlands. The modern edifice dates back to at least 14,000 years ago. It towers above the tropical jungle on the east side; on the other sides flat plains of ash have been eroded by heavy rains into steep-walled canyons up to 600 m deep. The earliest report of an eruption was in 1628. Almost continuous eruptions were reported from 1728 until 1916, and again from 1934 to the present. The almost constant activity has caused frequent changes to the morphology of the summit crater complex.

Resumen de Wikipedia

El Sangay es un estratovolcán ubicado dentro del parque nacional del mismo nombre en el centro del Ecuador, en las estribaciones orientales de la Cordillera de los Andes hacia la selva del Amazonas. El Volcán Sangay ha sido conocido y respetado por las comunidades locales durante siglos debido a su historia de actividad eruptiva, y su nombre en lengua kichwa significa "montaña ardiente". En términos de reconocimiento científico, se cree que el volcán fue estudiado por primera vez por el explorador alemán Alexander von Humboldt en el siglo XIX. Es un volcán continuamente activo ubicado en la República del Ecuador. Es el volcán más activo del Ecuador, y es conocido por su expresión explosiva la cual se manifiesta por nubes gruesas de ceniza, que han formado una especie de bóveda desde 1976.
