The Scientific Committee of the Special Plan for Civil Protection and Attention to Emergencies due to Volcanic Risk (PEVOLCA) meeting this Saturday has recommended keeping the volcanic traffic light in yellow in the Summit area “the process continues and it is not ruled out that it may have a rapid evolution to short term ”, is reported in a press release.
The experts have indicated that “overall, a low seismicity is maintained, although since 03:00 UTC (04:00 in the Canary Islands) after the occurrence of a magnitude 3.2 earthquake with intensity III, an intensification of seismicity has begun. , with numerous earthquakes with events located both at depths of 6-8 km, and superficial (0-2 km) ”.
In this scenario, the committee considers “probable the occurrence of felt earthquakes of greater intensity, which can cause damage to buildings. They can also cause rockfalls in the surroundings of Puerto Naos (from La Bombilla to El Remo) ”.
In addition, the experts pointed out that “the deformations are still ongoing, maintaining the speed of yesterday, being compatible with a source of surface deformation. Nor have they ruled out the beginning of other phenomena observable on the surface (changes in temperature, odor and color of the water, anomalous behavior of animals, etc.).
In this sense, they ask the public to “notify the authorities if they observe any anomaly.”
The Scientific Committee is coordinated by the General Directorate of Security and Emergencies of the Government of the Canary Islands and is made up of representatives of the National Geographic Institute (IGN), Higher Council for Scientific Research (CSIC); The Canary Islands Volcanological Institute (Involcan), the Geological and Mining Institute of Spain (IGME), the State Meteorological Agency (AEMET), the Spanish Institute of Oceanography (IEO), the University of La Laguna and the University of Las Palmas de Gran Canaria.
The Pevolca establishes a volcanic traffic light as an alert system to the population based on four colors depending on the risk: green, yellow, orange and red. In yellow, information to the population, surveillance measures and monitoring of volcanic and seismic activity are intensified.
The population must be attentive to the communications of the competent authorities in Civil Protection, through official channels and the media.
“Before a volcanic eruption, there is a gradual increase in seismic activity, which can last for a long time and can be perceived by the population, so you must remain calm,” he stresses.
At a yellow traffic light, it is recommended to know the communications network of the environment in which you reside for a possible evacuation and to have a family home located outside the risk areas.
“You have to plan a small backpack or travel bag in case evacuation is determined, with a mobile phone with charger, personal medications and important documentation,” they recall.
