This phenomenon, characterized by low-energy pulses and low-frequency signals, has been meticulously monitored by the volcanic surveillance network. Specialists have found no anomalies that could cause concern among the population or visitors to the National Park.
The activity began on April 3 at 10:47 PM and has continued intermittently. Of the total records, IGN technicians have manually located 31 events. The magnitudes of these earthquakes are extremely low, ranging between 0.4 and 1.6 mbLg, which explains why they have not been felt by the residents of Tenerife.
The hypocenters are located at considerable depths, between 5 and 18 kilometers. According to volcanologists, this type of hybrid activity, accompanied by long-period signals (LP events), is common in active volcanic systems and reflects deep adjustments that do not imply an imminent risk on the surface.
The 131 new earthquakes on Teide do not increase the danger.
The reassurance is based on the seismicity pattern. The IGN emphasizes that these earthquakes do not show the repetitive structure of the “seismic swarms” observed in previous episodes, such as in February. These are isolated events with insufficient energy to suggest magma ascent or critical pressure on the Earth's crust.
The island boasts an exceptional safety network, with over 100 stations and fixed sampling points that analyze seismicity, ground deformations (geodesy), and gas emissions and geochemistry of the volcanic edifice in real-time. Despite the clear message, the IGN maintains technical caution, indicating that current data is provisional due to the low amplitude of the signals.
