SANTA CRUZ DE TENERIFE, 20 Sep. (EUROPA PRESS) –
The Cabildo de Tenerife, through the Instituto Volcanológico de Canarias (Involcan), has been working for months on the volcanic crisis on the island of La Palma, and this was indicated on Monday morning by the island president Pedro Martín, who has indicated that for some months, scientists from Involcan have been collaborating “intensely” with the monitoring of seismic movements and the possible eruption in Cumbre Vieja.
“The outcome has occurred, as we all know, and therefore that team of scientists will continue to work on La Palma, to which must be added the Brifor staff with their vehicles and the Tenerife Fire Department, as well as the insular director of Cabildo Security, Rubén Fernández “, he comments in a note.
The Volcanological Institute and ITER are monitoring this volcanic emergency with a total of 27 people, 14 of them in Tenerife.
Another 13 work on the island of La Palma, four belonging to Involcan itself and nine to ITER.
As a result of these works, a first estimate has been made of the amount of sulfur dioxide (SO2) emitted into the atmosphere by the current eruptive process at Cumbre Vieja during its first day.
This assessment has indicated that about 6,000-9,000 tons per day have been emitted, assuming that the wind at 3,000 meters has been during the afternoon of September 19 with intensities around 2.8 -4.2 meters per second (meteorological data provided by Aemet).
This estimation has been made after taking four measurements samples with a miniDOAS type optical sensor in a land mobile position.
As of this Monday, this type of measurements will be carried out in an area mobile position thanks to the collaboration of the Helicopter Unit of the Civil Guard in Tenerife, as happened during the underwater eruption of El Hierro.
Daily monitoring of this parameter will be essential to analyze the evolution of the current process and to be able to use this methodology to certify the final date of the eruption.
