Teide Volcano Shows Increased Swarm Activity, No Eruption Expected

The director of Spain's Instituto Geográfico Nacional, Itahiza Domínguez, warned that seismic swarms around the Teide volcano are likely to continue and some may be felt, but an eruption is not expected in the short or medium term. Scientists and regional authorities have agreed to meet every three months to monitor the activity more closely.

In 2026, ten swarms were recorded west of Las Cañadas, almost double the total detected between 2016 and 2025. Activity occurred in two main periods: a strong activation phase from February to March, followed by a quieter phase, and a resurgence from June to July. Swarms this year have lasted longer, with some persisting for days, and are linked to deep fluid movements.

The monitoring effort includes regular seismic measurements on Mount Teide and coordination between the special civil protection plan (Pevolca) and scientific teams to ensure timely response to any changes.
