Canary Islands Monitor Renewed Teide Quakes
The IGN continues volcanic monitoring in the Canary Islands after recording about a dozen deep earthquakes in Teide's caldera in early March, alongside other tremors across the archipelago.
Volcanic monitoring continues in the Canary Islands because earthquakes have started up again in Las Cañadas del Teide. While the National Geographic Institute (IGN) doesn't classify this as a 'swarm' of quakes, it does highlight how geologically active the islands always are. The IGN, according to the EFE news agency, detected about a dozen earthquakes in the Teide volcano's caldera in early March, following a week with no recorded activity in the area.
These quakes occurred deep underground, between 8 and 14 kilometers, with the strongest one measuring magnitude 1.4. Itahiza Domínguez, who heads the IGN in the Canary Islands, explained that these aren't typical 'seismic swarms.' Instead, they are individual tremors with a distinct high-frequency signature, similar to what has been observed in this area for years. This recent activity at Teide follows seven earthquake swarms recorded there in February.
Beyond the Teide caldera in Tenerife, the IGN also recorded eight other earthquakes across the Canary Islands during the first three days of March. Information about these quakes, which is published on the institute's website if they exceed magnitude 1.5 or are felt by people, shows they occurred in various locations.
On Sunday, March 1, three quakes were recorded: some in the Atlantic Ocean and one near Frontera on El Hierro island. All of these were stronger than magnitude 2. On Monday, March 2, activity focused on Agaete in Gran Canaria and the Atlantic, with two quakes measuring 1.5 and 1.6. Then, on Tuesday, March 3, three more tremors were noted: two in the Atlantic at magnitude 1.7, and a stronger one, magnitude 2.6, again near Frontera.
