Canary Islands - October 13th, 2011

Underwater eruptions from the El Hierro volcano, which commenced on Monday, are continuing a few kilometres off the town of La Restinga, the southernmost town in The Canary Islands. The estimated 670 residents of the town have been evacuated from their homes. Hierro, a shield volcano, has had a single historic eruption from the Volcan de Lomo Negro vent in 1793.

In this image a large green stain is visible on the surface of Las Calmas Sea (lower left corner). The large stain is emanating from two fissures on the sea bed, approximately 700-1000 metres below the surface.

The eruptions take place amidst an unprecedented number of earthquakes in El Hierro. The number of earthquakes recorded since July 17, 2011 on El Hierro has now exceeded 10,500. However, the number and intensity of earthquakes has reduced signifcantly in the past 48 hours.
