How Tsunami occurs?

How Tsunami occurs?
As one plate subducts below another, pressure builds after many years, resulting in a section of the megathrust giving away.
As this section gives way. 1 ruptures the ocean floor, resulting in a massive displacement of water, causing a Tsunami. Tsunamis are barely fell as a ripple on the ocean surface, but as the wave reaches land, they increases in size as the water becomes shallower.
World’s worst Tsunamis
In Chile, Japan and Russia on February27, 2011, thousands died after an 8.8-magnitude earthquake. Many who survived the quake were killed hours later by a massive tsunami. Waves of up to 1.5 meters [5feet] went on to hit far – flung Pacific regions from the Russian far east and Japan to New Zealand’s Chatham islands.

The biggest Tsunami  occurred on July 9, 1958 in Lituya bay, Alaska by a magnitude of 8 earthquake causing massive landslides. Waves reached an unbelievable heights of 1,720 feet, killing more than 36,000 people. We shall pray to god for the people who died in these biggest Tsunamis for the peace of their soul.
