Awoke to the news of the massive earthquake in Japan, which has clocked in at magnitude 8.9. This is only marginally less strong than the 9.1 quake that produced a devastating tsunami in the Indian Ocean on Boxing Day 2004. This quake has produced tsunami waves of between 7 and 10 metres (24 to 33 feet), which have carried away anything in its path. This has varied from people to vehicles, boats and buildings. The pictures on NHK World, relayed through most broadcasters, are terrifying. The Japanese are used to earthquakes, but a near-9 is off their scale. As I type this, the tsunami is still rolling across the Pacific, currently affecting Indonesia. However, the tsunami warning extends right down the west coast of the entire American continent, with the wave currently closing in on Alaska.
A tsunami is not a wave, as you may see along the seashore. It is a wall of water.
The Pacific Tsunami Warning Center is issuing hourly updates.
The WCATWC Warning Center covers the North American coastline, also hourly.
