What Is the Smallest Volcano in the World?
Cuexcomate is considered the world's smallest volcano, with a diameter of 75 feet. Cuexcomate is located in a suburb of the city of Puebla, N.M. It is considered an inactive volcano.
Cuexcomate formed in 1664 when a larger volcano called Popocatépetl erupted. Scientists do not believe that Cuexcomate is likely to become active. Nonetheless, Popocatépetl is becoming more active, resulting in evacuations of surrounding villages from time to time. Some experts speculate that an eruption of Popocatépetl has the potential to spur Cuexcomate into activity. If Cuexcomate does erupt, such an event is likely to expand the side of the volcano at least to some degree.
