During the time, separating human epoch and Neocene, Antarctica had undergone grandiose changes. First of all the geology had changed: the continent has moved from polar position aside Meganesia, having put one of its coasts to Indian ocean. Movement of tectonic plates had resulted in increased volcanic activity: along the coast of the continent turned to Meganesia numerous islands, including rather large ones, had risen from the ocean. Another center of volcanic activity is Antarctic peninsula (a place of contact of South American and Antarctic lithospheric plates) where some large active volcanoes exist. In other places of continent dead volcanos exist.
