A new seismic swarm has been registered by the National Geographic Institute (IGN) in the south of La Palma in the deadly Cumbre Vieja, the same area where it was rocked by 50 earthquakes in three days last weekend.
Forty-four new small earthquake with magnitudes between 0.9 and 2.1 were recorded between 1.52pm on Friday to 4.17pm on Saturday.
The earthquakes from the huge Cumbre Vieja volcano sparked panic across the Canary Islands, with volcano experts pulled in to examine the unusual seismic activity.
María José Blanco, director of the IGN in the Canary Islands, said this swarm was the same “in principle” as last weekend.
She said: “Seismic instability is compatible with a small intrusion of magma to about 20 kilometers deep. ”
Ms Blanco said the latest swarm was “less energetic” than the last.
It comes after La Palma was rocked by more than 40 seismic movements of low magnitude and intensity between 1.5 and 2.7 on the Richter scale, according to the data of the National Geographic Institute.
The biggest earthquake, recorded at around 1pm on Saturday, October 7 was a magnitude 2.7 and took place in the area of the Natural Park Cumbre Vieja, 28 kilometres deep.
