New Seismic Activity Detected Under Tenerife’s Teide

Fresh Seismic Swarms Recorded Beneath Tenerife

The National Geographic Institute (IGN) has detected a new episode of seismic activity beneath Tenerife between last Saturday and the early hours of this Monday. The tremors originated from two distinct locations: the area around Izaña and to the west of Las Cañadas del Teide.

Earthquake Series Near Izaña

On Saturday 11 April, a small, low-magnitude earthquake swarm occurred in the Izaña zone. The IGN’s automatic systems detected a total of 16 tremors, of which 11 were subsequently located. Their magnitudes ranged between 1.0 and 1.9 mbLg and were located at depths of between 3 and 10 kilometres. IGN sources detail that these are volcano-tectonic events, similar to those recorded in the same area between May and November 2025, within a comparable range of magnitude and depth.

Low-Frequency Activity Near Teide

Separately, in the early hours of this Monday between 00:10 and 00:30, seismovolcanic activity was registered. This consisted of two low-frequency pulses (known as LP events) as well as several low-magnitude hybrid seismic events. The IGN points out that the LP events are similar to those from February and March, though with lower amplitude and duration than those recorded previously.

No Cause for Public Concern

In total, the IGN’s automatic system detected 38 events from this latest activity, of which three were manually located at a depth of 12-13 kilometres in the area west of Las Cañadas del Teide. The IGN emphasises that this activity does not show a repetitive pattern in the form of families, unlike the activity observed since February. It adds that none of these events, neither the hybrid nor the LP tremors, has been felt by the population.

The institute also stresses that this type of activity, composed of hybrid seismic events accompanied by long-period signals (LP events), does not increase the risk of an eruption in the short or medium term (weeks or months) on Tenerife. Finally, the IGN indicates that, due to the low amplitude of the analysed signals, data concerning the number of events as well as the range of their magnitudes and depths remain provisional.
