The National Geographic Institute (IGN) has alerted the Canary Islands Civil Protection Service about increased seismic activity in Tenerife, particularly over the last few hours. The agency stresses that there is no immediate threat of eruption.
This warning follows heightened volcanic activity detected primarily west of the Teide National Park, where 221 low-frequency seismic events have been recorded in the past 48 hours.
From Saturday to Sunday morning, and especially during the early hours of Sunday, multiple low-frequency seismic pulses were noted in the historically active area. The initial alert was sent at 2:07 AM on Sunday as part of routine protocols. IGN sources indicated that such notifications have been issued before but had not previously been reported.
As this seismic activity intensified, IGN identified various volcanic events, including routine tectonic events, hybrid events, and low-frequency events, all correlated but not felt by the public.
Earlier, between Thursday and Friday, 79 earthquakes had already been noted in the same region. Most of the seismic activity has been concentrated in the western part of Las Cañadas, particularly affecting the municipalities of Guía de Isora, Vilaflor de Chasna, and Santiago del Teide. These events typically have magnitudes below 2 on the local scale, with depths mostly ranging from 10 to 15 kilometres below sea level.
IGN has confirmed that this recent surge in activity resembles patterns observed in February and March. However, due to the low amplitude of the recorded signals, current data on the number of events and their magnitudes and depths remain provisional. A more detailed analysis may lead to an increase in the reported events and specific magnitude ranges in the official IGN catalogue.
