text: At 5,230 m , Sangay Volcano ) is an active stratovolcano in central Ecuador , and is one of the highest active volcanoes in the world and one of Ecuador 's most active ones , erupting three times in recorded history . It exhibits mostly strombolian activity ; the most recent eruption , which started in 1934 , is still going on . Geologically , Sangay marks the southern bound of the Northern Volcanic Zone , and its position straddling two major pieces of crust accounts for its high level of activity . Sangay 's roughly 500,000 - year history is one of instability ; two previous versions of the mountain were destroyed in massive flank collapses , evidence of which still litters its surroundings today . Sangay is one of two active volcanoes located within the namesake Sangay National Park , the other being Tungurahua to the north . As such , it has been listed as a UNESCO World Heritage Site since 1983 .
