The team of scientists on board of the fuselage Ramón Margalef located yesterday the mouth of the underwater volcano in the sea of the Calms of the island of The Iron. This discovery has been possible thanks to the employment of an underwater robot designated Liropus with capacity to observe and collect samples until a depth of 2.000 metres.
The group of Spanish scientists, dependent of the Spanish Institute of Oceanography (IEO), has attained to situate a new volcanic building of conical form, with a diameter in the base of 700 metres, a height of 100 metres and a crater of some 120 metres of width.
According to the data registered, the base of the crater finds situated to 300 metres of depth. Likewise, and by means of the utilisation of ecosondas of main frequency, has been possible to locate the columns of gases and fluent that issues the volcano and other points of broadcast (fissures) that are causing that the stain of material eruptivo was expanding to the zone South of the island because of the strong currents and that, as they have photographed the satellites, surpasses in surface to the island of The Iron. For the responsible scientists of the finding, the location of the focus eruptivo submarine supposes all a scientific milestone since it is the first time that achieves locate a volcanic building of these characteristics. Besides, it treats of the first mission in which it participates the oceanographic fuselage Ramón Margalef since it went out of the city of Vigo the past 18 October course to the island of The Iron. The oceanographic campaign in which they have realised these discoveries realises in collaboration with the Oceanic Platform of Canaries (Plocan) and the Canarian Agency of Investigation, Innovation and Information Society (Aciisi), in the frame of support to the Scientific Committee of the Pevolca.
On the other hand, while the phenomenon eruptivo in the zone of the Sea of the Calms has suffered a remarkable descent, the experts of the National Geographic Institute (IGN) have alerted of an increase of the seismicity in the zone of Border. Specifically, the seismographs detected in the morning of the Tuesday, a total of 10 tremors with a depth of 22 kilometres. The one of main magnitude registered west of the municipality of Border that achieved 2,2 in the scale of Richter.
