An aerial view from the east shows the Pichincha volcanic complex, one of Ecuador's most active volcanoes, rising immediately above the capital city of Quito. Guagua Pichincha (left) and the sharp-topped Pleistocene Rucu Pichincha stratovolcano (right) form a broad volcanic massif overlooking Ecuador's largest city. The largest historical eruption from Guagua Pichincha took place in 1660 CE, when ash fell over a 1000 km radius, accumulating to 30 cm depth in Quito.
