To the west of Hammerfell, you have Yokuda, the old homes of the Ra Gada, or Redguards. As far as I can remember, it was wracked by disaster, natural or no.
To the south and southwest of Summerset Isle, you've got Thras, the home of the Sload, as well as Pyandonea, the home of the Maormer, or the sea-elves.
To the north of Skyrim is Atmora, the old home of the Nedic men; it's almost completely inhospitable now due to terribly cold climates.
To the east of Morrowind is Akavir, which is home to a plethora of strange races, which can be read up on http://www.imperial-library.info/akavir/
And there's also Aldmeris, which is the old homeland of the elves; no-one has a clue where it is or whether it still exists.
