The National Geographic Institute (IGN) has issued an alert to the Civil Protection Service of the Government of the Canary Islands due to a notable increase in the frequency of seismic activity on Tenerife. Despite the intensification, it is stressed that there is no eruption danger in the short or medium term.

The intensification of seismo-volcanic activity has been registered mainly in the area west of Las Cañadas del Teide. Over the last 48 hours, 221 low-frequency events have been recorded. These were particularly concentrated between Saturday night and Sunday morning, and more significantly, between Sunday night and Monday morning at 2:07 AM, when several low-frequency seismic pulses were detected in the same area where usual activity has been ongoing for months.
Following the detection of these pulses, and in accordance with established protocols, the alert was sent to Civil Protection. Sources from the IGN have indicated that such notifications have been made previously, although they were not publicly disclosed until now.
The registered events show a high correlation with each other since Saturday afternoon. It is important to note that none of these seismic movements have been felt by the population. During this period of intensified activity, the IGN has identified various types of events, including ordinary volcano-tectonic events, hybrid events, and LP events.
