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, had a magnitude of 2.7 and took place in the area of the Natural Park Cumbre Vieja, 28 kilometres deep.
The second largest quake, of 2.6, took place at 1.23pm on Sunday in the same area, while the third quake erupted at midnight on Monday, reaching a magnitude of 2.1, according to the Volcanological Institute of the Canary Islands (Involcan).
The earthquakes from the huge Cumbre Vieja volcano have sparked panic across the Canary Islands, with volcano experts pulled in to examine the unusual seismic activity.
This has now risen to 50 tremors in three days after 10 more tremors were recorded from the huge Cumbre Vieja volcano, which sits on La Palma, overnight and into dawn.
One of them reported a magnitude of 2.1, which took place just after midnight.
A 2.8-magnitude earthquake was also recorded in the northwest of the Canary Island of Gran Canaria, according to the National Geographic Institute (IGN).
The seismic movement took place just before midnight on Tuesday at 23 kilometres deep and northwest of La Aldea de San Nicolás.
The shocking rise in such a short amount of time has prompted volcano experts from the Volcanological Institute of the Canary Islands (Involcan) to intensify surveillance on the islands.
María José Blanco, director of the National Geographic Institute in the Canary Islands, said the island has “never recorded a similar swarm” and although the energy levels are low and very deep, it is different from the seismic activity they have recorded so far.
The Ministry of Territorial Policy, Sustainability, and Security of the Government of the Canary Islands, respecting the Special Plan for Civil Protection and Emergency Care for Volcanic Hazards, will meet with the Scientific Committee of Evaluation and Monitoring of Volcanic Phenomena, to evaluate the data obtained from monitoring stations on the island.
A scientific team of five will also visit La Palma to keep track of the tremors in situ.
