Izquierdo stressed that the tests carried out have made it possible to verify a significant reduction in carbon dioxide levels both in the garages and in the homes located above them and in nearby buildings. “The results are being encouraging; we have seen that CO2 levels fall drastically not only in the intervened buildings, but also in a radius of about 30-35 meters around the polls,” he explained. “In the first test we have developed, some buildings that recorded peaks of up to 50,000 particles per million have now dropped to levels close to 1,500, so if we strategically use these new ‘punctures’, safety conditions could change very significantly throughout this area,” he added.
For her part, the head of volcanic surveillance of the IGN, Carmen López, stressed that the behavior of volcanic gases continues to be monitored permanently and recalled that the work is being carried out with scientific basis and maximum prudence. “The data obtained so far show a positive evolution and confirm that mitigation measures are contributing to a significant reduction in CO2 concentrations on the surface and inside buildings,” he said.
