Scientists warn of massive wave

While stressing that there is no indication it could happen soon, Atlantic coastlines in Europe, Africa and the Americas are under threat from a monster wave of Hollywood -- even Biblical -- proportions, scientists have warned.

They fear that a massive landslide following a major volcanic eruption in the Canary Islands would send a 300-foot wave across the Atlantic, causing devastation to coastal towns and cities.

British and U.S. scientists who have issued the warning predict that, in the worst-case scenario, the tidal wave would destroy the coasts of Florida and Brazil.

But the Western Sahara, Portugal, Spain, France and parts of the UK would also be hit.

They fear that the mega-wave -- know as a tsunami -- could be generated by part of a mountain twice the size of Britain's Isle of Man crashing into the sea following an eruption of the Cumbre Vieja volcano on La Palma, in the Canary Islands -- part of the Spanish island chain off West Africa.

Travelling at speeds of up to 500mph, the tsunami would be an unstoppable force and would be the biggest-ever recorded in history.

Previous research by Dr Simon Day, of the Benfield Greig Hazard Research Centre at University College London predicted that a future eruption of Cumbre Vieja was likely to cause the western flank of the mountain to slide into the sea.

The energy released by the collapse would be equal to the electricity consumption of the entire U.S. in six months.

With Dr Steven Ward, from the University of California, Dr Day has produced a new model that predicts more accurately how big the tsunami will be and where it will strike.

Immediately after the landslide, a dome of water almost 900 metres (3,000 ft) high and tens of kilometres wide will form, only to collapse and rebound.

Its first target was expected to be the West Saharan coast of Morocco, where the wave would measure a devastating 330ft from crest to trough.

Propelled by a series of crests and troughs, the tsunami would travel a distance of almost 155 miles in just 10 minutes, the model predicts.

Racing at the speed of a jet aircraft, it would reach Florida and the Caribbean in eight or nine hours.

A wall of water 164ft high -- higher than Nelson's column in London's Trafalgar Square -- would smash into the coasts of Florida and the Caribbean islands, the forecast predicts.

The northern coast of Brazil would be hit by a wave more than 130ft high.

The wave would travel four or five miles inland, flattening everything in its path.
