Ancient Indians (Harappan Settlement) were Aware of Tsunami/Storm Protection Measures:A New Interpretation of Thick Walls at Dholavira, Gujarat, India

Archaeological evidence from Dholavira, a Harappan city in Gujarat, India, suggests that its massive fortification walls—up to 18 meters thick—may have served as tsunami or storm protection rather than military defense. Located along a historically vulnerable coastline and during a mid-Holocene period marked by higher sea levels, the site's thick walls likely represented an advanced understanding of natural disaster risks among ancient Indians. This interpretation challenges conventional views on the purpose of such structures, proposing that they were designed to mitigate catastrophic wave impacts rather than serve as defensive barriers against human threats.
