The Canary Island of El Hierro, situated in the Atlantic off the coast of Africa but under the governance of Spain, has been suffering a 'swarm' of earthquakes over the past few days.
Seismic activity began on the island last July with the gradual development of an undersea volcano just off the small town of La Restinga. Large bubbles of gas were seen rising to the surface of the sea and the residents of the island were in a constant state of alert in case an emergency evacuation was needed. The activity continued to grumble though until just before Christmas 2011 and then died right down.
According to Canaries News, eleven earthquakes were reported on El Hierro on Thursday June 14 ranging between 1.7 and 2.8 on the Richter scale. This time, the activity was located around the island's capital La Frontera.
