The volcano is an almost perfect cone, and is covered in alternating layers of lava flows and thick pyroclastics. At Popo's peak there is an oval crater, which is 2,007 by 1,312 ft across, with almost vertical walls. A small spatter cone rises at the center of the crater some 115 ft.  Since the Spanish conquest of Mexico Popo has erupted at least 36. Popo has been continuosly erupting since 1995.
