Question

What are some tsunami prediction methods?

Answer 1

Dear friend believe it or not. I have issued the warning of on coming Tsunami 2 hours before it struck our Indian coast. The alert message issued by me is this to our local T.V.stations. " I have sensed a major earthquake which I never heard in the history of earthquake. Please alert the people to be ready to move to a safer place in case of emergency. The sea water may rise to a greater height." But the alert message issued to the local T.V.stations were ignored. Now after 2 years they say that if this type of warning comes from meteorological department we should have obeyed. The earthquake alarm designed by me has given the warning signal for an unusual time of 12 minutes. The book written by Mr Bruce Bolt clearly says we should stay away from beaches because the Tsunami may struck long after the shaking is stopped. That is why I issued the alert message .Please read My study on prediction . But the subject is very big. You can contact me at [e-mail]
Methods for prediction of earthquakes & Tsunami
.
1. Seismic gape: - The earthquake at a particular place may occur for every fixed gape of time. By knowing the past records of the quakes affected at that place may help to decide when the earthquake is next due.

2. Planet position.: - When the stress is accumulated at the tectonic plate boundary and the same time if the position of more than 2 planets comes in a straight line this may help to accelerate the earthquakes. There fore the full moon days and new moon days are more vulnerable days for earthquakes. Some time this method fails why? Think of a sick patient. New moon and full moon days are dangerous for only sick patents. These days will not affect the healthy people. The same way if there is no accumulated stress at the tectonic plate boundaries no need to worry about the planet positions.

3. Sun rays falling method: - If you observe the position of the sun rays falling on our wall at a particular time on all days it should form an angular infinity symbol. If there is any deviation in its path it means that there is some difference in height of the earth. That means some strain noticed at that place. Somebody claims that they can predict the place of epicenter by observing this. The laser beam measuring method of earth height from satellite also will help.

4. MCDB:- Chinese scientist claims that they can predict up to 60 % accuracy by sensing electro magnetic rays.

5. Cloud forming: - Few hours to a few days before the occurrence of earthquakes a cloud reader claims that he has noticed a peculiar mosaic type of formation .We may also notice some lightening in the sky.

6. By sound :- A professor from Ajmeer University claims that he was able to hear a low frequency noise under 125 meter depth in a bore well. The same thing was reported by one Mr. Nair that he heard some roaring noise under the earth one week before the occurrence of earthquake in Gujarat.

7. By frequency of waves :- Mr Richter Allen of Berkley University claims that he can decide the magnitude of earthquake just 4 seconds after observing the frequency of the primary wave. Present method needs the full seismographic picture to find the real magnitude that too from as many places as possible to have fairly accurate results. His claim has got some truth because when there is a slip of bigger tectonic plate the frequency of quake will be less. If a small tectonic plate slips the frequency of the waves will be more.
8. There are several changes in nature and in the behaviors of animals and birds can be observed before an earthquake and Tsunami.. The deep sea fishes will come to the shore or die on beaches. The water will reseed.

Answer 2

It's veryhard. I suppose one way would be to set up a bouy system around the key areas where tsunamis are likely to strike. Any unusual activity reported by these bouys would alert scientisits to incoming tsunamis. One problem with this is that there is only a short time span of maybe 3 hours before the tsunami hits therefore not leaving a loty of time for evacuation.

This is one way.
