The port town of Dholavira in Gujarat, the fifth largest Harappan site, might have been destroyed by a massive tsunami, a study by CSIR-National Institute of Oceanography (NIO) has revealed.

“The results clearly indicate that massive tsunamis are not uncommon in the region. The thick wall in Dholavira shows that Harappans were not only aware of the potential threats from tsunamis, but they were also pioneers in coastal disaster management.

The study has proposed that the thick wall was built to protect the town from extreme oceanic events such as storm surges and tsunamis, Naqvi said.

A unique feature of Dholavira is the presence of a 14-18 meters thick wall, apparently built as a protective measure.

Naqvi said CSIR-NIO has carried out additional work at this site with a team of palaeoclimatologists, archaeologists and geophysicists from the institute surveyed a hitherto unexcavated area using Ground Penetrating Radar and systematically collected soil samples.

For example, the Makran Earthquake of November 28, 1945 generated a huge tsunami, over 10 meters in height that devastated large areas along the northern shores of the Arabian sea.
Naqvi said the exact timing of the sediments deposited in Dholavira is yet to be established.
