La Palma update 16th september 2021: Seismicity continues
Miguel Ángel Morcuende, head of the Environment and Emergencies service of the Government of La Palma, has been appointed technical director of PEVOLCA and will be responsible for directing and coordinating all actions carried out under the Plan itself. To meet the telecommunications demands that an emergency could bring, the government has decided to upgrade the existing Canary Islands Emergency and Security Network (RESCAN).
Regarding the seismic swarm, the earthquakes have decreased slightly in both number and magnitude, although it is stressed that the intensification of activity in the short term cannot be ruled out. The average depth of the seismicity as further decreased however, being recorded largely at 4-5 km, however low magnitude shallow seismicity (1-3 km depth) also continues to be recorded. Across the island, inflation continues to be recorded, with up to 10 cm of vertical movement recorded, coincident with the location of the majority of the seismicity.
