Iran,Japan region and Philipines Earthquakes on predicted date ,21st December 2010

hi
please note three major quakes on the predicted date of 21st December 2010
Iran---6.5
Japan region--7.4
Indonesia---6.2
Are these by chance? or fluke?Let us be open about it.Can plate tectonic explain such clusters of major quake,on given date and on different plate boundries?
In fact averaging out of major quakes (6+) ie 140 odd in a year is misleading. Earthquakes occurs in clusters. If I give 40 odd dates in a year for 6+ quakes and with window period of + or - 24 hrs ,my average will be too high
