Sangay (also known as Macas, Sanagay, or Sangai) is an active stratovolcano in central Ecuador. It is the most active volcano in Ecuador, having erupted three times in recorded history. It exhibits mostly strombolian activity; the most recent eruption, which started in 1934, is still ongoing. Geologically, Sangay marks the southern boundary of the Northern Volcanic Zone, and its position straddling two major pieces of crust accounts for its high level of activity. Sangay's approximately 500,000-year-old 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.
