The Cumbre Vieja volcano in La Palma, one of Spain’s Canary Islands, erupted two month ago. The lava has destroyed 1.134 hectares and has already reached the Atlantic in two places on the island’s west coast, falling off cliffs into the ocean and then adding to the coastline with a total of 48 hectares of lava landfill. Geological evidence suggests that a eruption of the Cumbre Vieja Volcano could cause a catastrophic failure of La Palmas west flank, drop-ping 150 to 500 km3 of rock into the sea. Waves generated by the run-out of a 500 km3 (150 km3) slide block at 100 m/s could transit the entire Atlantic Basin and arrive on the coasts of the Americas with 10-25 m (3-8 m) height.
