Since last Friday, the IGN has detected a new episode of seismic activity in the Las Cañadas del Teide area, on the island of Tenerife. A total of 131 hybrid events have been recorded, manifesting as low-energy pulses accompanied by low-frequency signals.
Out of this total, the National Geographic Institute has manually located 31 earthquakes. Their magnitudes range between 0.4 and 1.6 mbLg, and they occurred at depths between 5 and 18 kilometers.
The first event was registered on April 3rd at 10:47 PM, and the activity has continued intermittently. Unlike the activity observed since February, this series of events does not show a repetitive swarm pattern. It is important to note that none of these recent tremors have been felt by the population.
This type of activity, composed of hybrid seismic events accompanied by long-period signals (LP events), does not increase the short or medium-term eruption hazard on the island of Tenerife.
The IGN, as the entity responsible for volcanic surveillance in Spain, maintains an extensive network of over 100 stations, equipment, and fixed sampling points on the island. This infrastructure allows for comprehensive, real-time monitoring and evaluation of any changes, alterations, or anomalies in seismicity, deformations, and geochemistry that could indicate an evolution in the short, medium, or long-term risk of a volcanic eruption.
Finally, the agency clarifies that, due to the low amplitude of the analyzed signals, the data regarding the number of events and their magnitude range are still provisional. It is anticipated that, after a more detailed analysis, the total number of events could increase.
