MMMMM
The Volcanological Institute of the Canary Islands (Involcan) has reported the detection of a seismic swarm in Tenerife, consisting of dozens of small earthquakes, 26 of which were detected in the southwest sector of the Las Cañadas del Teide crater.

This activity was recorded between 1:42am and 6:08am on Tuesday, according to the volcanological institute's report released yesterday (Wednesday).

The hypocentres of these earthquakes are concentrated in the southwest sector of the Las Cañadas caldera (as highlighted by the red dots on the image below) at depths ranging from 5 to 10 kilometres, but the biggest recorded magnitude of these tremors was only 1.2 on the Richter scale.

NNNNN

Involcan noted that since June 2017, Tenerife has experienced an increase in microseismic activity within the island. This increase has been marked by 113 low-magnitude seismic swarms, including three hybrid seismic events.

This increase in seismicity is believed to be due to a pressurisation process within the volcanic-hydrothermal system, likely linked to the injection of magmatic gases into the system.

Importantly, Involcan emphasised that this seismic activity does not pose any danger to the population and does not indicate a change in the probability of a volcanic eruption occurring in Tenerife in the short to medium term.
