If I die here, please still try to get me home.

A Japanese government panel has warned that an tsunami as high as 30 metres could crash in on Hokkaido if an earthquake of magnitude 9 occurs. The panel assumed the "worst-case scenario" and said that an earthquake was imminent around the Japan Trench and the Kuril Trench. The panel however acknowledged that it is difficult to calculate the probability of such an earthquake but pointed out that every 300-400 years a massive earthquake has taken place. The last one occurred in the 17th century.
