This discovery has lot of connections with the occurances described in ancient literary works of Tamil. The oldest sangam extents like Agananooru, Purananooru, Tholkappium talk of the first and second tamil sangams which happened in Old Madurai and Kapaatapuram. Old madurai was described as a the capital of ancient pandya rulers situated in Lemuria or Kumari kandam which is a sunken landmass south of kanyakumari and connected east africa and west australia. Even the destruction of Old madurai and the migration of people to the present day tamilnadu and kerala is aptly described in the oldest availble sangam literature. This phenomenon is well explained by the theory of Plate Tectonics which speaks of the migration and shrinking of Indian plate along with Australia as they were previously connected with Africa.
In addition, Silappathikaram points out the occurrance of kadalkol or Tsunami submerging the old kaveripoompattinam or Poompuhar in the eatern coast due to a deadly volcanic eruption in indonesia. Thus Tamil literature has a well recorded proofs for those geological occurances.
