The crater of La Cumbre volcano as seen from above Fernandina Island.
A volcano on uninhabited Fernandina Island, in Ecuador’s Galapagos archipelago, produced an explosive eruption followed by a week of flowing lava.
The National Galapagos Park authorities said the eruption of La Cumbre was accompanied by a 5.2 magnitude quake.
There was no immediate word on the threat to the island's endangered wildlife.
La Cumbre is the most active of the Galapagos volcanoes, and the one nearest the mantle plume that formed the island chain.
In 1968, the caldera floor dropped 1,150 feet (350 metres) following a major explosive eruption.
