Mount Teide in the Teide National Park

Throughout the month of June, a total of 182 earthquakes were detected in the area of ​​the Canary Islands

The National Geographic Institute (IGN) detected, between 21:01 yesterday and 04:32 (UTC) this Tuesday, a total of 30 small earthquakes in Las Cañadas del Teide, of which 14 have been located mainly southwest of Pico Viejo and northeast of Guía de Isora.

The magnitudes of the earthquakes have been between 0.6 and 1.9 (mbLg) and the depths between 8 and 23 kilometres, the IGN has informed in a note.

The seismic activity of the last hours is located in an area with numerous micro seismic activity detected and located on a regular basis, does not pose any risk to the population and is within normal parameters in active volcanic areas, such as the island of Tenerife.

In fact, throughout the month of June a total of 182 earthquakes were located in the area of ​​the Canary Islands, with a maximum magnitude of 3.3 mbLg for the earthquake that occurred on the 12th at 19:10 (UTC) , 10 kilometres deep, with an epicentre located about 150 kilometres northwest of the island of Lanzarote.

On the 28th at 01:16 (UTC) an earthquake was located west of the island of Fuerteventura, about 35 kilometres from the coast, with a magnitude of 2.4 mbLg and a depth of 4 kilometres, which was felt with intensity II (EMS98) in the town of Pájara.

Between the islands of Gran Canaria and Fuerteventura, during that month, another 5 earthquakes of smaller magnitude were located, with a dispersed epicentral distribution.

Activity continued between the islands of Gran Canaria and Tenerife, with 57 localized earthquakes, at depths between 1 and 35 kilometres and magnitudes between 0.3 and 2.1 mbLg.

In the interior of the island of Tenerife, seismic activity has continued, mainly in the areas near Icod de los Vinos, Vilaflor, Teide-Pico Viejo and Guía de Isora, with a total of 40 earthquakes located between magnitudes -0.1 and 1.6 mbLg and depths between 1 and 28 kilometres.

In the area of ​​the island of El Hierro, 20 earthquakes between magnitudes 1.4 and 2.5 mbLg and depths between 5 and 37 kilometres were located in June.

Nine of these earthquakes occurred on the night of the 10th, between 22:28 and 22:44, with magnitudes between 1.9 and 2.5 mbLg, depths between 32 and 37 kilometres and the epicentre west of Orchilla.

There is no news that these earthquakes have been felt by the island's population.

In La Palma, 39 earthquakes have been located with magnitudes between 1.0 and 2.2 mbLg and depths between 3 and 37 kilometres.

On the 25th, at 7:19 (UTC) a seismic series began, located to the south of the island, in the Cumbre Vieja area, with 320 detected earthquakes and 37 located with magnitudes between 1.1 and 2.2 mbLg and depths between 18 and 37 kilometres.

This series ended on the 27th and has the same characteristics as the rest that have been located in the area since October 2007.

The results obtained from the observations made by the Permanent GNSS Stations of the Canary Islands Volcanic Surveillance Network and through InSAR processing do not show any significant deformation that can be associated with volcanic activity.
