While Ravana from the southern part of Bharatavarsha is called a Rakashsa, the people of Atala, Atlantis were called Asuras.
This term set me to search for a landmass which had a culture similar to Sanatana Dharma.
One finds references to this in the Ramayana where Sugriva directs hs army to search for Sita in Peru, identifying it with the Nazca Lines, which he called
as Shiva’s Trishul Mark, the Nazca Lines resemble the Trishul Mark.
The description of Tripura confirmed suspicion that Atlantis is Tripura mentioned in the Purana and destroyed by Lord Shiva.
