Tsunami is <span>a large wave usually caused by an undersea earthquake.
Explanation
</span>Tsunamis are big<span> waves caused by earthquakes or volcanic eruptions </span>beneath the ocean<span>. </span>go in<span> the depths of the ocean, </span>moving ridge<span> waves </span>don't<span> dramatically increase </span>tall<span>.
H</span>owever because the<span> waves travel </span>inland,<span> they build up to higher </span>and higher<span> heights </span>because the<span> depth of the ocean decreases.
The speed of </span>moving ridge<span> waves depends on ocean depth </span>instead of the space<span> from the </span>supply<span> of the wave. </span>moving ridge<span> waves </span>might<span> travel as </span>quick<span> as jet planes over deep waters, </span>solely deceleration<span> down </span>once reaching<span> shallow water.</span>

I have attached an image that might help you understand the concept a bit better.
I hope this helps! I'm happy to answer any other questions you might have :)
