This afternoon, Terra Noticias/Agencia EFE reported an eruption 2000 metres below sea level in the Las Calmas sea.  Spanish newspaper El Mundo placed the depth at 1300 metres.

Initial reports of the eruption came from crews on four separate ships.

Scientists remain unclear if the emissions are gas or lava.

“The eruption takes place amidst an unprecedented earthquake swarm in El Hierro. The number of earthquakes recorded since July 17, 2011 on El Hierro has now exceeded 10,000.”

Hierro, a shield volcano, last erupted in 1793. The eruption, which produced lava flows, lasted approximately one month.

Although government authorities have suspended ferry activities to and from the 285 square-km island, and have recommended that boats should not sail closer than four miles off El Hierro, and have warned divers to suspend all activities, the estimated 11,000 residents of El Hierro were being reassured not to be alarmed.

  1. I have to admit that I would find it very comforting that the government is saying you should not be concerned and are not at risk, if I was a resident of El Hierro, all the while knowing that all boats are being told not come near the island and ferry service is suspended. I hope they have a large food and fuel storage on the island, as who knows how long the eruption will go on. And I hope they have their personal jet packs ready to use to get off the island should it become necessary.
