The Volcanological Institute of the Canary Islands (Involcan) and the National Geographic Institute (IGN) have registered this Tuesday a hybrid event swarm of very low magnitude, located under the Teide volcanowhich does not imply a greater probability of a rash.
Involcan reports on its social networks that the Canarian Seismic Network operated by this entity has identified more than 630 events up to 12:30 p.m., all of small magnitude and located at depths of between 9 and 12 kilometers.
This seismic swarm has characteristics very similar to those that were recorded in Tenerife on October 2, 2016, June 14, 2019 and June 10, 2022.
The most likely origin of this type of swarm is the movement of fluids such as steam, gas or water, inside the hydrothermal system of the El Teide volcano, adds Involcan.
Also, the National Geographic Institute (IGN) states that series of this type have been recorded on numerous occasions in the area, the first antecedent being the signals recorded in 1980 in the microseismicity campaign carried out in Las Cañadas and which showed that this type of activity could be recurrent.
As indicated, the high detectability of the Canary Islands Seismic Network of the IGN currently allows detecting and locating this activity, related to processes within the Teide-Pico Viejo complex.
The analyzed activity indicates a readjustment of pressures in the lower part of the crust, due to the volcanic nature of the insular building and the magmatic processes in depth, details the IGN.
It highlights that this type of activity is to be expected on active volcanic islands, and may remain at that depth or may give rise to shallower seismic activity in the future, without this pointing to an eruptive process in the near future.
In addition, he comments that the activity in all these series begins with the recording of a long-duration signal, without defined seismic phases, and with high frequency content, subsequently giving way to a long series of hundreds of events of small and similar magnitude, that occur at almost regular intervals of time, in the form of “drum beats”.
