The Canary Islands Seismic Network detected the episode between 6:34 PM and 11:00 PM last Friday. According to technical data, this is the fourteenth swarm of this type recorded on the island since October 2016, showing characteristics very similar to previous events.
The scientific body points out that the most likely cause is the injection of hydrothermal volatiles of magmatic origin into the island's hydrothermal system. This is considered a recurring process supported by geochemical and geophysical evidence, such as increased diffuse carbon dioxide emissions at the Teide crater and slight ground deformation in the northeast sector.
The institute has conveyed a message of calm to the population, emphasizing that the episode does not change short or medium-term forecasts. However, Involcan notes that this swarm serves as a reminder that the process responsible for the increased volcanic noise in Tenerife remains active with no signs of subsiding.
