The seismic activity recorded in recent days in Las Cañadas del Teide does not anticipate a volcanic eruption in the short term, since there are no indications that this is the case, insist the National Geographic Institute (IGN).
IGN sources consulted by Efe explain that “small groups” such as the 25 earthquakes located in the early hours of this Saturday are somewhat “more normal” than the seismic swarm on Friday, when 458 minor tremors were recorded, and of which they have three records in the last six years.
This area, abound from the IGN, usually has “pulse seismicity” of between five and 10 earthquakes, although last night there were 25 and one of them had a magnitude of 2, which “is still low.”
The main hypothesis of the latest seismic swarm in Tenerife is that it is related to a degassing process, since under the island there is “hot material” and there may be “small contributions that accumulate over years”, although “this is difficult say it with total certainty,” Itahiza Domínguez, a seismologist at the IGN, told Efe yesterday.
Seismic activity that has nothing to do with a hypothetical eruption on Teide
The island of Tenerife has recorded some 25 earthquakes in the Teide areaspecifically to the southwest of Pico Viejo, from 00:00 hours this Saturday and until 05:15 hours, being the largest magnitude 2, according to data from the National Geographic Institute (IGN) collected by Europa Press.
As for the movement of the greatest magnitude –that of 2 mbLg–, it took place at 02:48 hours northeast of Guía de Isora and at a depth of 23 kilometers.
Meanwhile, the 25 earthquakes detected since last midnight have been at depths that ranged between eleven and 26 kilometers.
On the other hand, during the early hours of Thursday to Friday, the IGN and the Volcanological Institute of the Canary Islands (Involcan) detected a ‘swarm’ of hybrid events of very low magnitude in the Cañadas del Teide, southwest of Pico Viejo, in which 458 events have finally been detectedof which 13 have greater magnitude.
