The Biggest Tsunami ever!

Without underestimating the suffering of those in Japan, Christchurch, Haiti and other earthquake ravaged places at present, we are still all lucky it was not worse. As the media have drummed into us, this was a mega quake, measuring 8.9 on the Richter scale, and it generated a devastating tsunami with waves up to 10 metres high (incredible video here). In 1953 in Alaska, an earthquake measured at 8.3 on the Richter scale generated a tsunami. The wave that hit reached a height of 524 metres. I'll repeat that. 524 metres of water crashing down! Putting that in perspective, that's higher than the Empire State building!
