Seismic activity in the palm continues to fall and deformation loses speed

The General Directorate of Safety and Emergencies of the Government of the Canary Islands, in application of the Special Plan for Civil Protection and Emergency Attention by Volcanic Risk of the Autonomous Community of Canarias (pevolca), keeps the Island of the Palma in 'Yellow Traffic light' by Volcanic risk after consistent that seismic activity decreases and the deformation of the terrain loses speed.

Thus, from the Scientific Committee it is concerned that there is a "clear decrease" of the 'seismic swarm' activity although there is a "remarkable intensity" in the episodes that occur in a range of between 6 and 8 kilometers.

Therefore, shallow seismicity is predominant and deformation is still underway albeit at a lower speed, being compatible with a more superficial source of deformation. In this way, the Canarian Executive Bulletin exhibits that "the process continues and can have a rapidly short-term evolution" because the decrease in seismicity "can be transitory and does not necessarily imply a paralysis of volcanic reactivation".

In fact, from the Committee, they point out that it is "expected" that the greater intensity senses occur and "is not disposable" the beginning of observable phenomena on the surface. Likewise, and with respect to a possible landslide of the west flank of 'Old Summit' and the consequent formation of a megatsunami, the Scientific Committee highlights that "there is no data that support this hypothesis" and lacks a proven scientific basis.

Therefore, the 'yellow traffic light' is maintained in the area of mallet, fuence, the passage and the plains of Aridane and a change is not ruled out if the process intensifies in the short term. The Scientific Committee indicates that before a volcanic eruption, there is a gradual increase in seismic activity that can be prolonged for a long time and can be perceived by the population, so it should be kept calm.

The Security Counseling of the Government of the Canary Islands has requested the Ministry for the ecological transition and the demographic challenge the assignment of a coordination and observation (ACO) for the monitoring and monitoring of seismic activity on the island of La Palma.

The aircraft left this Friday first-time from its base in Muchamiel, in Alicante, from where it took off with Córdoba for a first scale prior to its displacement to Canarias. In Lanzarote plans to make a technical stop before reaching the palm in the late afternoon.

This aircraft will fly over the island to transmit photographs and videos through mobile telephony GPRS / 3G / 4G and microwave, both visible and infrared spectrum, to the Operations Central of the Ministry of Agriculture, Fisheries and Food and the Mobile Units of Analysis and Planning displaced on the ground.

The Director of Public Administrations, Justice and Safety, Julio Pérez emphasize that, in this phase, the priorities of the Government of Canarias are focused on the reinforcement of surveillance media, the increase of scientific teams on the ground and preparation of the device of evacuation, if necessary.

The request for the incorporation of this aircraft is part of the agreements reached in the Directorate of the Special Plan for Civil Protection and Emergency Attention by volcanic risk (pevolca), in coordination with all administrations involved. In the current yellow alert phase, the preparation of an eventual evacuation will be coordinated by the Cabildo of La Palma, together with the municipalities involved.
