How it was possible for me to issue the Tsunami warning?A clarification in brief.?

Question

The book written by Mr. Bruce bolt says we should keep away from beaches if we sense earthquake. Tsunami may strike long after the shaking is stopped. I know the concept of Richter scale the long time of shaking of small amplitude also from large earthquake. Since I kept my quake alarm on unsecured wooden show case in first floor the amplification factor helped me to sense the feeble waves. That day was full moon day. The possibilities of raising the water will me more on that day in sea. I issued the warning like this “I have sensed very big earthquake which I have not heard in the history of earthquake. The sea water may rise to a great height. Therefore advice the people to be alert to move to a safer place in case of emergency." Don’t mistake that this instrument will give fore warning of earthquake or Tsunami. But this will sense all the earthquake waves from all the direction at all the angle when the force increases the set perfect limit by inbuilt calibration mechanism.

But you cannot post a tsunami warning by yourself. Although you sound educated, if everyone could report a tsunami, there wouldn't be a minute that ticks by where they wasn't a warning.

Answer 2

I am just a lay person, but it seems to me that you did everything you were physically able to do.

You warned that there had been an earthquake - the biggest ever in the history of your knowledge.
You warned that the sea waves would rise to great height.
You told people to be prepared to get out fast.

You could not start yelling "tsunami!!" If you did not have the means to actually KNOW one was coming.
You did everything you were able to do, and probably a lot more than most would have done in your place.
It is very hard to step out and say for sure something is going to happen if you have no proof or instrumentation to show it. If it does not happen you would lose all credibility for the future confidence of your citizenry.
You did the very best you could do. Rest easy.

Answer 3

The mechanics that lead to tsunami are quite complex. A single seismometer (or quake alarm if you wish) doesn't give sufficient information. You really need a network of seismometers scattered around for instance the indian ocean. By analyzing the recorded vibrations that a quake generates, seismologists can tell where and how deep it took place. Only very few quakes actually raise tsunamis and it takes fairly complex computer models to correctly predict whether a tsunami can be expected. Fortunately, seismic waves travel a lot faster than water waves which leaves the scientists a couple of hours to raise the alarm.

Answer 4

If your question is how do you personally issue a tsunami warning, I'd suggest working with your local emergency response or law enforcement officials and maybe contacting the Pacific Tsunami Warning Center.
