Ground deformation using InSAR method of Tenerife Island between 3 and 15 June (image: Sentinel-1/Alaska Data Search Vertex, processed by Martin Kelko)

Since June 18, 2026, the Canary Islands Seismic Network (INVOLCAN) has detected an increased seismic activity beneath Tenerife, with more than 200 low-magnitude volcano-tectonic microearthquakes recorded over the last 48 hours at depths of approximately 10 km beneath the southwestern sector of the Las Cañadas caldera. The strongest event reached M 1.1.

This activity is consistent with the recurrent seismic unrest observed since 2016–2017 and is interpreted as the result of pressurization of the volcanic-hydrothermal system caused by the injection of magmatic fluids. Supporting evidence includes elevated diffuse CO₂ emissions in the Teide area and minor ground deformation detected since 2024.

According to current observations, there is no indication of an increased likelihood of a volcanic eruption in the short or medium term.
