Hawaii has its own history of mega-tsunamis, most recently about 100,000 years ago. “One block of rock that slid off Oahu is the size of Manhattan,” wrote Becky Oskin in Live Science.

A mega tsunami taller than a 50-story skyscraper once engulfed an island off the west coast of Africa, ... generating a titanic wave 1,724 feet high (525 m), the largest ever recorded.

Researchers have unveiled the first direct evidence of these massive waves and linked them to bizarre seismic signals that baffled scientists.

The Tonga underwater volcanic eruption rivaled the strength of the largest U.S. nuclear bomb and produced a "mega-tsunami" nearly the height of a 30-story skyscraper, a recent study finds.

Unlike smaller tsunamis, which may only produce waves a few feet high, mega tsunamis are on a completely different scale. These waves can soar hundreds even up to 1,000 feet into the sky.

The largest wave in history: over 1,700 feet and a devastating megatsunami, ... These waves don’t travel far like traditional tsunamis; they hit hard, and close to home.
