Tsunami to hit Japan

Discovery or National Geo had a prog on this a while back called called Super Tsunami or something like that.

From NationalGeographic.com:

There's also the possibility that the eruption of an obscure volcano in the Canary Islands off the coast of Africa could send giant tsunami waves surging ashore from New York to Florida, as well as southern Britain.

A slab of rock about 35 miles (56 kilometers) long on the western slope of the volcano Cumbre Vieja is cracking. Scientists think an eruption could shear the slab away from the mountain, drop it into the sea, and send gigantic waves rolling across the Atlantic Ocean. About nine hours later, these waves—some of them 80 feet (24 meters) high—could strike the U.S. East Coast.

50cm doesn't sound too serious I know, but tsunami waves are different to your normal waves you'd see coming in and out down at Salthill.

They just keep coming one after another with little receeding, if at all. 50cm is still enough to cause serious flooding but, of course, not the massive loss of life that was witnessed 2 years ago in the 'Big One'.
