A submarine volcanic eruption is taking place approximately 5 kilometres off the southern coast of El Hierro, the smallest of The Canary Islands.

The Mayor of La Frontera (El Hierro), David Cabrera, confirmed in an interview on Radio iron Garoé that ‘underwater eruption’ is taking place about 900 metres beneath the sea surface five kilometres south of La Restinga. The eruption has been ongoing for four hours, the Mayor said.

Spanish newspaper laopionion.es quoted the Minister of emergencies of the Cabildo of El Hierro, Maria of Carmen Morales, as saying the eruption is taking place because ‘the seismic movement of 4.3 occurred on Saturday afternoon caused a fissure, from where the energy is been released’. Scientists remain unclear if the emissions are gas or lava.

A meeting of PEVOLCA – Actualidad Volcánica de Canarias, comprising representatives of Instituto Geografico Nacional (IGN) and The Canary Islands Government, took place on the Spanish Island. In a statement issued shortly before 4 p.m. local time, the IGN stated (translated from spanish language press release): “…although there is no certainty that at the moment is producing an underwater volcanic eruption, since the last morning there has been a release of fluids and volcanic gas on the southern coast of the island.”

“Scientists from IGN have reported to the direction of the Plan all the indicators that have been analyzed to point towards the possibility of the beginning of an eruptive process that has changed the type of waves that have registered seismographs in the last hours, implying the beginning of emission of gases or lava…”

“The helicopter of the emergency and rescue of the Government of the Canary Islands (GES) group has done reconnaissance flights during the morning without exit of volcanic material to the surface.”

“Although this activity is not exposed to, the direction of the PEVOLCA encourages people to perform their usual tasks normally and to remain attentive to any unusual activity”, the statement added.
