Second submarine eruption during 2012 ?
Update Fri 08 Feb 09:25
Some new data suggest that a second submarine eruption might actually have occurred at El Hierro occurred at the sea floor SW off El Hierro Island during the strong seismic crises in end of June - July 2012.
Evidence of this claimed eruption were sonar images which, according to the researchers, showed volcanic material erupted in an area less than 2 NM from the coast and at depths of 64 to 88 meters. The material formed a plume that rose up to a depth of 48 meters. However, some doubts about this evidence remain because while the earthquake swarm was very intense, there were no shallow earthquakes associated with the possible opening of a new eruptive vent.
