New Seismic Episode Recorded Under Teide
The National Geographic Institute (IGN) has detected a new episode of seismic activity beneath Las Cañadas del Teide in Tenerife. Since last Friday, it has counted 131 hybrid seismic pulses, which are low-energy events accompanied by low-frequency signals. From this total, the IGN has manually located 31 earthquakes, with magnitudes ranging from 0.4 to 1.6 mbLg and depths between 5 and 18 kilometres.
Activity Pattern and Public Impact
The first event was recorded on 3 April at 22:47 and activity has continued intermittently since. IGN sources detail that this activity does not present a repetitive pattern in the form of swarms, unlike the activity observed since February. Furthermore, none of these recent events have been felt by the population.
No Increased Eruption Risk
The IGN specifies that this type of activity, composed of hybrid seismic events accompanied by long-period signals (LP events), does not increase the short or medium-term risk of an eruption on the island of Tenerife. It reiterates that, as the body responsible for volcanic surveillance in Spain, it has deployed a network of more than 100 fixed stations, equipment, and sampling points on the island to monitor and evaluate the most significant parameters with current technology.
Comprehensive Real-Time Monitoring
This infrastructure allows for exhaustive real-time tracking of any change, alteration, or anomaly in seismicity, ground deformation, and geochemistry that could indicate an evolution in the short, medium, or long-term hazard of a volcanic eruption.
Provisional Data Subject to Change
Finally, the Institute notes that due to the low amplitude of the analysed signals, the data on the number of events and their magnitude range are still provisional. It adds that when a more detailed analysis is carried out, the number of recorded events could increase.
