The IGN has reported the detection of seismo-volcanic activity beneath Tenerife during last Saturday, April 11, and the early hours of Monday, April 13. This activity was concentrated in two distinct locations on the island: the Izaña area and the western part of Las Cañadas del Teide.
On Saturday, April 11, a small seismic series of low magnitude was recorded in Izaña, with a total of 16 earthquakes automatically detected. Of these, 11 were subsequently located, with magnitudes ranging between 1.0 and 1.9 mbLg, and depths between 3 and 10 kilometers. These volcano-tectonic events are similar to those observed in the same area between May and November 2025.
In the early morning of Monday, April 13, between 00:10 and 00:30, seismo-volcanic activity was registered west of Las Cañadas del Teide. This consisted of two low-frequency pulses, known as LP events, as well as several low-magnitude hybrid seismic events. The IGN's automatic system detected 38 events, of which three were manually located at depths of 12-13 km.
This activity does not present a repetitive pattern in the form of families like the activity observed since February.
The IGN emphasized that none of these events, neither the hybrid nor the LP, were felt by the island's population. Furthermore, the scientific center clarified that this type of activity, characterized by hybrid seismic events accompanied by long-period signals, does not increase the risk of a volcanic eruption in the short or medium term in Tenerife.
For comprehensive monitoring, the IGN maintains a network of over 100 stations, equipment, and fixed sampling points in Tenerife. This allows for real-time evaluation of any changes in seismicity, deformations, and geochemistry that could indicate an evolution in volcanic hazard. Current data is provisional due to the low amplitude of the signals, and a more detailed analysis in the official IGN catalog is expected to increase the number of events and provide more precise magnitude ranges.
