For 21 minutes, between 3:07 and 3:28 AM, consecutive pulses of low-frequency seismic activity were detected west of Las Cañadas del Teide. This increase prompted the National Geographic Institute (IGN) to issue a warning to the Civil Protection Service of the Government of the Canary Islands.
In the preceding 48 hours, a total of 222 tremors were recorded, most located in the western area of Las Cañadas del Teide, at depths between 10 and 15 kilometers. The activity began on June 18th, with most earthquakes having magnitudes below 2.0 mbLg.
IGN seismologist Rubén López explained that while such warnings are typically issued when certain thresholds are exceeded, the information in this instance was leaked to a media outlet. The recorded sequence did not reach the intensity of previous seismic crises, such as the one on February 10th.
Specialists indicate that the presence of volcano-tectonic, hybrid, and low-frequency events is compatible with fluid circulation at depth but does not necessarily imply an acceleration of the volcanic process. None of the earthquakes were felt by the population.
“"The activity recorded between Sunday and Monday has been quite significant, although not as much as in February."
The IGN maintains a network of over 100 stations on the island for real-time monitoring of seismicity and other parameters. Currently, experts rule out an imminent eruption and suggest this activity could be part of the usual dynamics of Tenerife's volcanic system, now detectable due to instrumentation.
