The cause for the Tsunami, as deduced by the seismologists, is
A). Gravitational pull of the moon
B). Low pressure trough in the ocean
C). Deformation of sea floor and vertical displacement of water
D). Sudden change in the monsoon wind

Seismologists say only earthquakes measuring greater than 7.0 on the Richter scale can produce a major tsunami. The friction between two slow-moving plates of the Earth's crust creates vast amounts of seismic energy which is released in the form of an earthquake.
