In the above image two large green stains are visible on the surface of Las Calmas Sea. In addition to the stains, officials from Spain’s Instituto Geográfico Nacional (IGN) have reported a strong smell of sulphur and dead fish floating on the surface.

The IGN said the large stains emanated from two fissures on the sea bed, approximately 700-1000 metres below the surface.  Scientists say they are hopeful this week’s eruptions will reduce pressure and the potential for eruptive activity occurring on the 285 square kilometre island. …

.. A ROV (Remotely Operated ‘underwater’ Vehicle) is scheduled to arrive in El Hierro on Monday to undertake a seabed study.

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