IGN Detects Seismic Activity Near Tenerife’s Mount Teide; Volcanic Alert Level Remains Unchanged

The National Geographic Institute (IGN) recently detected seismic activity near Las Cañadas del Teide, drawing fresh attention to Tenerife’s geology. While the activity has caught the interest of scientists, experts are urging the public to stay calm, noting that these tremors do not change the current volcanic risk level or suggest an imminent eruption.

Between Thursday afternoon and early Friday morning, sensors recorded 48 low-frequency pulses, 27 of which were precisely located. These events were concentrated in the western part of the caldera at depths of 8 to 15 kilometers. The strongest tremor reached a magnitude of 1.9.

Geophysicists explain that these types of signals—known as long-period and hybrid events—are common in complex volcanic systems like Tenerife’s. Unlike the seismic swarms seen in recent months, this activity does not follow an unusual pattern. The IGN noted that because the signals were weak, the exact magnitude and location of the tremors may be updated as more data is analyzed.

This activity is part of the ongoing monitoring of the volcanic complex, where low-frequency tremors often signal natural adjustments within the magmatic-hydrothermal system. Because there is no sign of increased volcanic danger, the alert level remains unchanged. Authorities emphasize that current monitoring systems are fully capable of distinguishing between normal background activity and any signals that would require emergency action.
