Fernandina Island (Spanish: Isla Fernandina) is the youngest and third largest island in the Galapagos, as well as the furthest west. It has an area of 642 km2 (248 sq mi) and a height of 1,476 m (4,843 ft), with a summit caldera about 6.5 km (4.0 mi) wide. It is younger than Isabela, being only less than one million years old since its formation. Like the other islands, it was formed by the Galápagos hotspot. The island is an active shield volcano that has most recently erupted in March 2024.
Ferdandina is the youngest and third largest island in the Galapagos, as well as the furthest west.[5] It has an area of 642 km2 (248 sq mi) and a height of 1,476 m (4,843 ft), with a summit caldera about 6.5 km (4.0 mi) wide. The caldera underwent a collapse in 1968, when parts of the caldera floor dropped 350 m (1,150 ft). A small lake has intermittently occupied the northern caldera floor, most recently in 1988. Due to the recent volcanic activity, the island does not present much plant life and has a mostly rocky surface. Visitors to Fernandina Island will be taken to see only the outskirts of the crater for safety reasons. Two types of lava flow can be observed, ʻaʻā and pāhoehoe.
Wildlife
Punta Espinoza is a narrow stretch of land where hundreds of marine iguanas gather in large groups on black lava rocks. The famous flightless cormorant inhabits this island as well as penguins, pelicans and sea lions. The Narborough Island tortoise is a highly elusive species of Galápagos tortoise restricted to the island, thought likely extinct when no sighting had been made for 113 years after 1906, one old female being found in 2019.[6]
