Monitoring systems of the National Geographic Institute (IGN) have detected a resurgence in seismic activity beneath Tenerife. Since the night of April 3, at least 131 hybrid seismic events have been recorded, a common signal in active volcanic areas. These very low-energy movements have had no impact on the population.
Preliminary data from the agency, responsible for volcanic surveillance in Spain, indicates that the first event occurred on April 3 at 10:47 PM. Since then, activity has been intermittent west of Las Cañadas del Teide. Of the 131 automatically detected events, 31 have been manually located by IGN technicians.
The recorded earthquakes exhibit very low magnitudes, ranging between 0.4 and 1.6 mbLg, and are located at depths of 5 to 18 kilometers below sea level. These values are consistent with those observed in recent weeks, and so far, none of these movements have been felt by the island's inhabitants.
The island has over 100 volcanic surveillance stations, including seismic sensors, ground deformation systems, and geochemical control points. This network allows real-time monitoring of any changes or anomalies that could indicate an evolution of the volcanic system.
Despite the increase in seismic registrations, the IGN has emphasized that this type of activity does not imply an increased risk of eruption in the short or medium term in Tenerife. Experts explain that these hybrid seismic events, accompanied by low-frequency, short-duration signals (known as long-period or LP signals), are typical in active volcanic systems.
The National Geographic Institute has warned that, due to the low amplitude of the signals, current data remains provisional. As a more detailed analysis is conducted, the total number of detected events could be adjusted, and more precise magnitude ranges will be published. Scientists maintain continuous monitoring of Tenerife's subsoil, considered one of Europe's most closely watched volcanic territories.
