cycle quakes and eruption

hi
we have on 14th April 2010,china quake,Iceland volcanic eruption and west begal cyclone.As per general theory of tidal force, after 7.5 days we may witness some of the above. This is because,after each 7.5 days, Moon moves 90 degrees and acquires next potent position
Most likely hood of renewed volcanic eruption (this was posted eariler -yesterday -below the list of dates for the year 2010)
