Tenerife (Canary Islands (Spain)): The Instituto Volcanológico de Canarias (INVOLCAN) issued a report for Tenerife on 11 February 2026 (local). Between 0430 and 0500 on 11 February, a new signal with characteristics similar to the continuous LF event recorded on 10 February was recorded. The primary differences were a lower amplitude and a shorter duration. The low-magnitude, low-frequency (LF) volcanic earthquake swarm that began on 7 February continued, with more than 260 small earthquakes recorded as of 11 February. The events are located in the SW sector of the Las Cañadas caldera, at depths between 8 and 12 km. The largest recorded earthquake to date had a local magnitude of 1.7. The alert level remained at “Green – Early warning” (level 1 on a 4-level scale).
