The northern flank of the volcano Cumbre Vieja on La Palma collapsed in the early hours of Saturday night, according to the Canary Islands Volcanology Institute (INVOLCAN).
Spain's National Security Department later said that the collapse of the flank had caused the release of large blocks of material and the appearance of new flows running through evacuated areas. According to the Spanish Institute of Geology and Mining, the blocks of lava slid down the side of the Cumbre Vieja volcano were the size of three-storey buildings.
The Cumbre Vieja volcano on La Palma began erupting on 19 September. The lava from the volcano is believed to have destroyed more than 1,000 buildings. More than 6,000 people have been evacuated from the disaster zone, while some of them have been allowed to return home.
