The Indian subcontinent consists of the subcontinent, the continent of Australia, Tasmania, New Zealand, the bottom of the Indian Ocean, and the bottom of the southwestern part of the Pacific Ocean.
The shifting of the Indian past to the northeast creates pressure between the Indian past and the Eurasian past. This has resulted in the formation of the Himalayan mountain range and earthquakes continue to occur there even today.
The Indian past is estimated to have separated from Antarctica about $75$ million years ago.
This Indian past is believed to have covered a distance of about $5000 \ km$ so far.
