After 3 seperate volcanos erupted on LaPalma today I remembered a BBC Horizon program, it must have been around 20 odd years ago. They were talking about this happening on La Palma. What scientists are predicting is that a catastrophic collapse is likely to happen any time within the next few thousand years. Scientists also know that a collapse will not happen without any warning. They will be able to alert people to possible danger several weeks in advance. The western flank of the Cumbre Vieja volcano would slide down westwards into the Atlantic ocean. There would be very strong earthquakes across La Palma while the flank was sliding. As the flank slid into the sea, it would create a very large wave called a mega-tsunami. This wave would move rapidly westwards.
Most of the energy of the wave would head straight out across the Atlantic towards the United States, Bahamas and the Caribbean, but a smaller wave or waves would head in other directions too. All these waves would get smaller as they cross the Atlantic. However scientists believe that they could still be as much as 50 metres high, for example, when they reach the east coast of the United States.
