If this were to happen it would produce a tsunami 1,000 metres (3,281 ft) high at the island but a few hours later after it traveled thousands of miles and reached the eastern seaboard of the USA it would only be about 50 metres (164 ft) high.</div><div><br></div><div> John K Clark </div></div></body></html>
