Tsunami Earthquake Explained: How It All Started?<\/span><\/h1>\n

A tsunami earthquake usually starts when a large earthquake occurs beneath the ocean, especially in subduction zones where one tectonic plate is forced beneath another.<\/p>\n

In these zones, immense stress builds up as an oceanic plate pushes against and slowly slides underneath a continental plate.<\/p>\n

When this stress becomes too great, the edge of the overriding plate snaps and moves suddenly, often causing vertical displacement of the seafloor\u2014either lifting it up or pushing it down.<\/p>\n

This sudden movement displaces a massive column of seawater, creating either a bulge or a dip on the ocean\u2019s surface.<\/p>\n

Gravity then pulls the water back to its normal state, which triggers powerful tsunami waves that travel rapidly away from the epicenter across the ocean.<\/p>\n

In the deep sea, these tsunami waves might be barely noticeable, appearing as small swells.<\/p>\n

But as they approach shallow coastal waters, they slow down and increase dramatically in height, sometimes rising into walls of water that flood coastal areas.<\/p>\n
