950 Shakes Detected in a New Seismic Swarm at Teide
The National Geographic Institute (IGN) states that this type of movement does not imply a short‑term eruption.
The Instituto Geográfico Nacional (IGN) has detected intense activity beneath the subsurface of Tenerife. A new seismic swarm has shaken the depths of Las Cañadas del Teide, recording close to a thousand earthquakes within a short time span. This episode is the ninth of its kind recorded in the last decade and, notably, the third in just seven days.
The series of hybrid events began at 23:00 on Wednesday and continued through the night and the early hours of Thursday, according to IGN sources, who note an intense seismic activity over the past week.
- Total hybrid events recorded: 950
The figure could rise in the coming hours as detailed studies may identify additional weak signals that are currently difficult to detect.
Joint analysis of the series indicates that the activity is located in the western part of Las Cañadas del Teide, at depths of 7–8 km. This area has previously experienced similar seismic swarms in:
- November 1980
- October 2016
- June 2019
- June and July 2022
- November 2024
- August 2024
- 12 February 2026
- 16–17 February 2026
The IGN emphasizes that these hybrid seismic swarms do not increase the short‑term eruption risk on the island of Tenerife. It also reminds readers that a network of more than one hundred stations, equipment, and fixed sampling points is deployed across the island to monitor all possible parameters.
“An exhaustive real‑time monitoring of any change, alteration, or anomaly in seismicity, deformation, and geochemistry that could indicate an evolving short‑, medium‑, or long‑term volcanic eruption risk.”
