When Japanese are adopting my concept why our meteorological department criticizing me for using same?

I have attended an international seminar on Tsunami where the Japanese consulate explained that they advised their people to move away from seashore or to a high rise building as soon as they senses the earthquake waves even before the Tsunami warning is issued. That is what I did on 26th Dec 2004 at morning 2 hours before Tsunami struck our Indian coast. Because I sensed very feeble earthquake wave for 12 minutes with the use of simple equipment I designed. I know as per the concept of Richter scale that is also from very big earthquake. Seismologists do not understand the way I issued the warning or they pretend as if they don’t understand. I don’t know. I never claimed that I can predict earthquakes.But I can sense the wave before people sense it by the quake alarm and other instrumennts I have designed and available with me.
