Volcano-logical Institute confirms an increase in carbon dioxide emissions
Posted before 1 h ..
"The volcanological Institute of the Canaries (non-tip) confirmed the direction of the Civil Protection Plan for Volcanic Risk (Pevolca) a further
increase in the diffuse emission of carbon dioxide (CO2) into the atmosphere from the volcano of El Hierro, according to informed the Government of
the Canary Islands in a statement."
"The Regional Executive notes that, according to data from non-tip, the measured emission rate has reached the "1218 ± 46 tonnes per day", which is
the highest value observed since the beginning of magmatic reactivation takes place on the Island"
"Since last July 21 the non-tip has materialized over 7250 flow measurement of carbon dioxide diffuse through numerous scientific investigations
carried out in "the whole island subaerial volcanic edifice" which covers an area of 278 square kilometers, and which have contributed a lot
volunteers canaries. The purpose of scientific research is to contribute to the improvement and optimization of monitoring, since the gases are the
driving force of volcanic eruptions."
"The registration made more than three months ago the rate stood diffuse emission of carbon dioxide in the "331 ± 16 tons per day," the regional
government, adding that the average of the emanation is 345 tons per day. On October 6, prior to the underwater eruption that took place southwest of
La Restinga rate reached "990 ± 49", which means it was 2.8 times higher than normal average. Recent results show that this figure is now 3.5 times
higher than usual."
"The direction of Pevolca states that the diffuse emission of CO2 is one of the parameters of a volcanic eruption precursors, but it has to be
evaluated in conjunction with other deformation, and seismicity depth, among other things. Also remember that "we are in an eruptive process underway
in the south of the island, which generates greenhouse gas emissions in the Earth's surface."
