The Mega Tsunami That Hit Eastern Australia: Lord Howe

Eastern Australia has a hidden history of colossal mega tsunamis that reshaped the coast and left behind dramatic geological evidence. On Lord Howe Island, towering waves more than 100 meters high ripped vegetation away, hurled massive boulders inland, and capped headlands with layers of sand and shells from the ocean floor. These events were unlike any ordinary storm or cyclone, leaving behind scars carved into cliffs and stories that echo through Aboriginal oral traditions. This post explores the science, history, and mystery of the mega tsunamis that struck the Tasman Sea and eastern Australia.
