Miravalles (or Neo-Miravalles) stratovolcano rises above the floor of the Guayabo caldera and is the youngest feature of the Miravalles volcanic complex. It, along with Paleo-Miravalles volcano, was constructed within a caldera left by collapse of Cerro Cabro Muco volcano about 200,000 years ago. Cabro Muco volcano was itself constructed within the 15 x 20 km wide Guayabo caldera, which was formed during a major explosive eruption sometime between 1.5 million and 600,000 years ago.
