The island of El Hierro, the smallest and farthest south and west of the Canary Islands (anAutonomous Community of Spain), in the Atlantic Ocean off the coast of Africa, is also the youngest in the volcanic chain.
The October 2011 – March 2012 eruption was underwater, with a fissure of vents located approximately 2 km to the south of the fishing village of La Restinga on the southern coast of the island. As of June 2012, increased seismicity to the north-west of the vent suggests another phase in the area’s volcanic activity – comprising just deep-seated magma movements with associated earthquakes and deformation of the island at this June 2012 stage – is under way. A second phase of eruptive activity has not yet occurred, and it does not necessarily follow that it will occur.
Our ROV Sirio has recorded significant images of the submarine volcano at El Hierro.
The shots, made during the oceanographic campaign to study the volcano, conducted by the University of Las Palmas de Gran Canaria, on board the R/V Atlantic Explorer owned by QSTAR SLU, have provided scientists with valuable data on the state of volcano’s activity. Filming most striking are those carried in the mouth of the volcano, where you can see a “glowing meteor shower”, while in the surrounding areas, marine life is gradually recovering.
