SANTA CRUZ DE TENERIFE, Sep. 7 (EUROPA PRESS) –
The Volcanological Institute of the Canary Islands (Involcan) has certified that the diffuse CO2 emissions in the La Bombilla area, on the Tazacorte coast, are “clearly anomalous” more than a semester after the eruption ended.
They are approximately between 20 and 500 times higher than that registered for Cumbre Vieja since the diffuse emission of CO2 in La Bombilla began to be monitored and measured at the end of December 2021, comparing the rates per area unit. not by square kilometers.
The Involcan has measured the diffuse emission in Cumbre Vieja since the 1990s in an area of 220 square kilometers and since December it has carried out 34 scientific campaigns in La Bombilla, practically one every week, and each of them with 84 observation points.
In addition, it highlights that diffuse CO2 emissions could only be considered normal when per unit area in La Bombilla they are comparable to that recorded for Cumbre Vieja.
In general, he points out, “the diffuse fluxes of CO2 in volcanic soils of the Canary Islands are in the range of values from 1 to 10 grams per square meter per day, and in the case of La Bombilla average values have been recorded that exceed 1,000 daily grams per square meter”.
