Seismic activity surprises once again in Tenerife. The National Geographical Institute (IGN) reported on Friday that it detected several low-frequency seismic activity pulses between Thursday and Friday, with around 79 earthquakes recorded. However, the data from the Canary Islands Volcanology Institute (Involcan) is even more astonishing.
Since Thursday, the Canary Seismic Network has recorded an increase in activity on the island. In particular, over the past 48 hours, it has located more than 200 micro-earthquakes of a volcano-tectonic nature (VT) of very low magnitude in the southwestern sector of the Las Cañadas del Teide caldera at an approximate depth of 10 kilometres, as reported by the agency on its social media.
These low-intensity earthquakes have recorded a maximum magnitude of Ml 1.1 on the Richter scale.
Recent Activity
Involcan reminds us that this episode is part of the recurring seismic activity that Tenerife has experienced since June 2017.
In fact, similar to previous occasions, its origin is associated with a pressure process within the island’s volcanic-hydrothermal system, triggered by the injection of magmatic fluids.
“This process has been observed repeatedly since 2016 and is supported by various independent geochemical and geophysical indicators,” notes Involcan.
