How old is the Fernandina volcano?
one million years old
GEOLOGY: Fernandina is the westernmost island in the Galapagos Islands, the third largest and youngest of the islands, less than one million years old. It is the most volcanically active and sits at the center of the hot spot that created the Galapagos Islands.
When did Fernandina last erupt?
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….Ecuador.

When did Fernandina first erupt?
Based on analysis of satellite imagery, IG reported that an eruption of Fernandina started sometime during 2200 on 10 April and 0030 on 11 April. Several thermal anomalies were seen on satellite imagery, possibly indicating active lava flows.
Why is Isla Fernandina the youngest?
Fernandina Island and the Geological Formation of the Galapagos. The Galapagos Islands were formed by a hot spot (similar to how the Hawaiian archipelago was formed). This means that it is also the youngest island and the one that has been least affected by human activity.
