Amazing toll of El Hierro eruption
Can you imagine how much material it would take to fill 120,000 Olympic swimming pools?
This might give you some idea of the vast amount of debris which was produced last year during the much-publicised underwater vol-canic eruption just off the coast of El Hierro.
Figures produced by the Spanish Oceanographic Ins-titute show that an amazing 328 million cubic metres of material was pumped out.
The IEO carried out the research in conjunction with the University of Barcelona between October 24th, 2011 (15 days after the start of the eruption) and February 24th, 2012. The information has been published in the Geology magazine.
The Institute says this information will serve as a reference for the study of similar eruptions, both in the Canaries and on other volcanic islands. It is based on data obtained during the six geological campaigns carried out by the research vessel “Ramón Margalel”.
One of the scientific experts, Jesús Rivera estimat-ed that it woud take about 9,000 similar eruptions to create an island the size of El Hierro.
