The catastrophes of earthquakes and volcanoes are devastating to humans?

Earthquake Questions
yet they indicate a living and dynamic planet. How does plate tectonics help us predict where and when earthquakes will occur? Can we limit the devastation of earthquakes and volcanoes by knowing more about plate tectonics? Why does a seismic knowledge of the interior of the Earth help us on the surface? Should we initiate planning to avoid catastrophe-prone areas, or should we try to protect against those catastrophes as they occur?

1) Earthquakes are extremely common at plate boundaries. Knowing where these boundaries are gives us a better idea as to where to expect EQs
2) Yes and no. The more we know about plate tectonics the more we can learn about EQs. But EQs, though statistical in some ways, are still hard to predict.
3) Knowing the interior of the Earth helps us know how soon waves are going to end up in other places.
4) What hasn't been planned, plan and build away from prone areas. What has been planned and built needs protection and better warning systems.

First we should know to merit the inventions and claims to analys its truth.I am the one issued the warning 2 hours before Tsunami struck our coast. There is no secret in my prediction. The earthquake alarm designed by me just for the cost of about U.S $ 25 gave the warning for 12 minutes. As I know the concept of Richter scale I know that the earthquake sensed by my instrument should be from far away place and the magnitude must be very high. The book by name earthquakes author Mr Bruce A Bolt iv th edition says ( Page no 239 ) stay away from beaches and water front areas where Tsunami may strike long after the shaking is stopped. That is why I issued the warning to local T.V.Stations. They have not only ignored my warning they have also criticized me for my real useful observation.Even now nobody has shown proper interest to find the fact.There are several natural warning we get before major destruction takes place. Scientist have to come forward to find the truth.
