Question

what are modes of prevention for tsunami?

Answer 1

Earth surface is resting on many solidified pieces of lava… gigantic rocks... called plates...

When these rocks… called plates… move / rub / hit against one another… that piece of earth vibrates violently… we call it ‘earthquake’…

No one can predict earthquake… nevertheless, we can identify earthquake prone areas… and take remedial measures…

Answer 2

Precaution is the only mode of prevention from earthquake. Study properly about the factor of safety to be adopted for building structures as per the earthquake zone. The earth has been divided into 5 zones as per the probable intensity of earthquake that might occur

Answer 3

no one can prevent an earthquake it is a natural event in nature.

the cause of an earthquake is the movement of faults and Continental plate boundaries
