Cumbre Vieja Volcano -- Potential collapse and tsunami at
La Palma, Canary Islands
Abstract. Geological evidence suggests that during a future
eruption, Cumbre Vieja Volcano on the Island of La Palma
may experience a catastrophic failure of its west flank, drop-
ping 150 to 500 km3 of rock into the sea. Using a geologically
reasonable estimate of landslide motion, we model tsunami
waves produced by such a collapse. 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.
Good info here on a potential collapse scenario.
