Volcanic activity is particularly monitored in the Canaries. It is also there that an institute specializing in the observation of volcanoes has been installed. This aims to contribute to improving the management of volcanic risk in Spain (in the Canary Islands, the only volcanically active region of the national territory), and to optimize the management of the many advantages that result from it (geothermal resources , geotourism, etc.).

Seismic swarms 45462
The seismic activity of Cumbre Vueja has thus been monitored for a long time and seismic swarms (succession of earthquakes) had already been detected in 2012, 2020 and 2021. Last September 11 last September a new seismic swarm was detected: thousands of tremors located at a depth of eight to thirteen kilometers. Volcanologists believe that they are the consequence of the rise of magma in the earth’s crust. This anticipation enabled the authorities to initiate an emergency and evacuation plan for the populations, which had been prepared for a long time.
