Places like the Meenakshi Temple in Madurai, Krishna’s Dwarka or the various structures and temples found in Mahabalipuram are direct allusions to the mythical floods
as according to the legends, these places were either built by survivors of the floods or by a civilisation that was destroyed in the floods. The massive floods that are being talked about in these myths can easily be referred to the floods that occurred at the end of the ice age, submerging vast stretches of land.

At Dwarka and Mahabalipuram the ruins are too recent to support the contention of an ancient lost civilisation although this doesn’t stop Hancock from speculating that the underwater ruins at Mahabalipuram date to 5,000 years ago (as opposed to 1,500 years).

As per traditional belief, some part of the ancient town of Mahabalipuram had been submerged just off the shore temple and this story has been recorded by the several British travelers during the 18th – 19th century. During the underwater exploration of Mahabalipuram area in 2017, three sites along with a large number of scattered dressed stones were found in the intertidal zone. Calcareous material grown over these stone structures after their submergence in seawater was subjected to radiocarbon (14C) dating to infer submergence time-periods of these structures. Submergence date for the site I is the late 14th century CE; whereas the submergence date from the site II comes ~ 1st century CE. According to the water-depths from where the studied structural remains were excavated, and obtained 14C dates of submergence, it could be surmised that these stone-structures off Mahabalipuram town were submerged in two phases. The submergence might have been induced by natural events such as coastal cyclone activity or Tsunami that flushed off sand around these structures and raised the sealevels locally over the coast.
