Volcán Darwin, Dormant volcano in Galápagos Islands, Ecuador

Volcán Darwin, also formerly called Monte Williams, is a shield volcano on Isabela Island in the Galápagos, Ecuador. It is symmetrical, and its summit caldera, about 5 km wide, is almost entirely covered by lava flows. Its last eruption was in 1813, and fumarolic activity continues.

Volcán Darwin, formerly called Monte Williams, lies on Isabela Island and is named after Charles Darwin. Its shield shape has produced about 4,000 eruptions in 87,000 years, the last recorded in 1813. Heavy autumn rains in 1901 formed a lake inside the summit caldera.

The volcano is named after Charles Darwin, who visited the Galápagos in 1835 aboard HMS Beagle; earlier it was called Monte Williams. Its caldera once held a lake formed by heavy rains in autumn 1901. Excursions to the volcano are organized, and its activity today is fumarolic.

Volcán Darwin sits on Isabela, the largest Galápagos island, which is reached by boat or by flights to Puerto Villamil; the volcano itself is visited on guided excursions. Its activity is fumarolic, and autumn rains in 1901 formed a lake inside the summit caldera. The caldera floor is almost entirely covered by lava flows.

The caldera floor is almost entirely covered by lava flows, and heavy rains in autumn 1901 formed a lake inside the crater. The volcano is fumarolically active, and over 87,000 years since its formation it has produced about 4,000 eruptions.
