WOULD YOU PLEASE consider coming to this thread and setting them straight on the wildly astronomical impossibilities of drilling holes etc. and preventing such quakes and tsunamis? Several posters seem convinced that we'll have it all solved by technology before too long. Sigh.
Unfortunately there are those who hopes in technology far surpass the reality (I'm still waiting for my flying car). For the record, we are talking about a displacement on the TECTONIC scale over a length of probably several hundred kilometers laterally and miles deep over a fault plane surface of thousands of square miles (at least). We cannot yet predict times and locations for earthquakes, let alone identify where to drill a boring to some how 'relieve the pressure'.
