I believe that there's little chance of any further large mega-quakes this year in the same area to the March 11th 2011 mega-quake, but there's a good chance the we'll see a major or mega-quake (8+) further north, around Hokkaido that may cause deaths, including from tsunami of 100 feet height or more.

The only good news is that there would be minimal risk to any nuclear installations.

If it hits, it will most likely take place in May or June 2012 latest.
