2011–12 El Hierro eruption
The 2011–2012 El Hierro eruption occurred just off the island of El Hierro, the second smallest and farthest south and west of the Canary Islands (an autonomous community of Spain), in the Atlantic Ocean off the coast of Africa. The island is also the youngest in the volcanic chain.
