Mega-tsunamis are gigantic waves up to and exceeding 100 feet that can be triggered by similar events. Evidence of past mega-tsunamis exists in various places around the globe. For example, in the Bahamas there are 123,000 year old deposits including boulders weighing up to 2000 tons that are up to 20 meters above sea level and at least half a kilometer inland. These are theorized to have been deposited by a mega-tsunami caused by the El Golfo I collapse in the Canary Islands.
Now, scientists have identified a fault in the Canary Islands that sometime in the future could perhaps cause a mega-tsunami. The Cumbre Vieja volcano is found on La Palma in the Canary Islands. La Palma is one of the steepest islands in the world, as well as being the most active volcanic island in the Canaries. In 1949 an eruption caused a fault to occur on the flank of the volcano, and the entire west flank of the volcano moved 4 meters seaward before stopping. Since then there has been no further movement, but it is anticipated that eventually during future eruptions there will be a collapse. A chunk of the island the size of the Isle of Man will fall into the sea creating a mega-tsunami. Scientists have attempted to computer-model the results... one model suggests that following this event the main wave would travel westwards, reaching the east coast of the Americas six hours later, at which time the wave will still be an estimated 100-150 feet high, causing unimaginable damage.
