Updated 16 February: The scientific committee has concluded that the latest seismic cluster of tremors under Cumbre Vieja is the result of a new intrusion of magma of low volume at a great depth of around 30km. The Government confirmed that since 10 February, IGN has registered 928 seismic movements in and around La Palma, the majority of low intensity, and that vigilance in La Palma is greater than it has ever been. Next month, indeed, the Instituto Español de Oceanográfico will be conducting a new research exercise off the south coast of the island to continue studying the seismic activity. For the moment, IGN director in the Canaries and spokesperson for the scientific committee, María José Blanco, clarified that current measurements do not show any deformation of the terrain, and that the possibility of an eruption, at least in the short term, is unlikely.
Original post 15 February: As I posted last October, La Palma was experiencing a cluster of tens of seismic tremors registered under Cumbre Vieja. All were small – the largest was Richter 2.7 – and very deep. None the less, the authorities increased monitoring and said that although such clusters are not commonplace, it was not beyond the range of normal for an active volcano. Now, there is another seismic cluster, again in the south under Cumbre Vieja, but this time nearly a hundred tremors have been registered in just a few days, some fifty recorded in just a few hours last night. The Canarian Government has therefore convened the Comité Científico de Evaluación y Seguimiento de Fenómenos Volcánicos (Pevolca) to meet tomorrow, Friday 16 February. No doubt there will be further updates after that session, but in the meantime, please see HERE for more information about Pevolca and the Canarian Government’s protocols and plans in the event of volcanic and seismic activity.
