Overview
- The current swarm that began late Feb. 18 has surpassed 2,500 very small, hybrid earthquakes located roughly 7–9 km beneath the west of Las Cañadas del Teide.
- Two earlier swarms were recorded on Feb. 12–13 with more than 400 events and on Feb. 16–17 with at least 1,400 events, marking the most concentrated sequence in about a decade.
- Officials say the quakes have not been felt by residents and that gas emissions and ground deformation show no concurrent changes linked to this episode.
- PEVOLCA convened scientists and Tenerife municipal leaders for briefings, and the IGN is maintaining reinforced real‑time surveillance with a network of more than 100 monitoring stations and sampling points.
- The IGN attributes the signals to subsurface fluid movement rather than a magmatic intrusion, noting the tremors have weakened in recent hours and could subside.
