Where have mega tsunamis occurred in the past?

They discovered that at least eleven mega tsunamis had happened in the last 200,000 years, caused by island collapses in the Hawaiian and Canary islands. Where is one likely to occur in the future? The island of La Palma, in the Canary Islands off the coast of North Africa, was discovered to be in great danger of collapsing.

Another eruption could cause the western flank of the island to collapse in the Atlantic Ocean. When will a mega tsunami happen? No one knows. It will happen during an eruption of Cumbre Vieja. It is an active volcano, last erupting in 1949. However the next eruption may not destroy the island, the next 10 may not. Only on thing is certain – one-day an incredible force will surge through the Atlantic Ocean. How big would a mega tsuna
