“The March 19 SuperMoon is by far the most significant storm and seismic indicator this month, but it’s not the only one. Lesser geocosmic shock windows also up the ante for unusually strong storms and moderate to severe seismic activity (including magnitude 5+ earthquakes, subsequent tsunami, and volcanic eruptions). These lesser windows include March 1-7 (surrounding the new moon on the 4th), March 23-26 (bracketing the lunar south declination peak on the 25th), and from late on the 31st on into early April.”

So pretty much random predictions blanketing a significant portion of the month, and he still misses Japan. Which I’m sure he would have claimed credit for if it did fall within one of his multiple day ranges.
