After some decade my story will be published.I am the one issued the warning 2 hours before Tsunami struck our coast .I have used my scientific known knowledge and the instrument designed by me at the cost of just U.S $ 20 .The instrument was designed by me in the year 2001. Its usage was not accepted by some section of seismologist.It has proved its important on the day of Tsunami.But it has not yet come to rescue the people who are affected by several natural disasters.
