La Palma, like the other islands of the Canary Island archipelago, is a volcanic ocean island. The volcano rises almost 7 km (4 mi) above the floor of the Atlantic Ocean.What are facts about volcanic islands?
Volcanic islands are formed by volcanic activity on the seabed, often near the boundaries of the tectonic plates that form Earth?s crust. Where two plates pull apart, lava erupts to form an undersea ridge. Layers of lava build up until a ridge breaks the sea?s surface to form an island.Is La Palma still erupting?
The eruption is ongoing in Cumbre la Vieja volcano (La Palma Island, Canary Islands), and the lava flow has exceeded the pre-existing front moving south and reaching the coast at Playa de Los Guirres. The amount of the affected area by the lava is more than 988 ha. 7,200 people have been evacuated.
