Seismic Swarm Hits Tenerife, but No Immediate Eruption Threat
SANTA CRUZ DE TENERIFE, 4 July — The Volcanological Institute of the Canary Islands (Involcan) has reported a recent hybrid seismic swarm beneath Tenerife, stating it does not alter the short- or medium-term eruption risk.
The Canary Islands Seismic Network detected the swarm between 6:34 PM and around 11:00 PM on Friday. This marks the fourteenth such swarm observed in Tenerife since October 2016 and shares similarities with past events.
Involcan suggests this seismic activity is likely linked to the injection of hydrothermal volatiles from magmatic origins into the island’s hydrothermal system. The institute noted that this process has been recurring since 2016, supported by various geochemical and geophysical evidence—including increased diffuse carbon dioxide emissions at Teide’s crater and slight terrain deformation in the northeast volcanic sector.
Involcan reassured residents that this recent activity does not indicate an increased eruption risk in the near future. However, it serves as a reminder that the volcanic “noise” noted on the island since late 2016 remains active, with no signs of abating thus far.
