An accented declivity less in the side-sea makes the waves to lose force, attenuating tsunami
A bigger depth in the hillside plays the waves for top, amplifying its power
Volcanic eruptions inject tons of wash in the oceanic soil, generating devastadoras waves
Submarine earthquakes dislocate the crust oceanic, pushing the water mass for top
A gas bubble appears in the deep one of the ocean, with the same effect of an uncommon explosion
