Japan Earthquake.8.9 and tsunami-11th March 2011

hi
please note Japan major quake and tsunami.Actual predicted date is 20th March 2011(please note no place is predicted).However, as per cycle quake theory(7/8 day before and after) a quake of 6.5 to 6.8 was expected (not 8.9)
Now ,some of the questions plate tectonics and seismologist need to answer to people ,who have lost their loved ones ,and hard earned money,are
1)If major quakes occur due to build up stresses on the plate boundries,can we not measure the stresses? and predict the dates?
2)Even after spending millions of Dollars ,in research (in the same direction) ,if we can not predict the dates,Do we need to stop and rethink?
3)Is is not possible that,there could be other reasons for major quakes?(other than plate tectonics)
4)Are we wasting tax money paid by the people?
5)Shall we support any alternate theory,or at least have a look at it?
6) Are we treating effect(plates) as the cause (of quakes)?
Think out of the box
