Here's my guesses...

Very likely:
Lavastorm (outside Solusek & Najena)
South Karana (outside Paw)
Dagnor's Cauldron (perhaps anywhere)
Ocean of Tears (perhaps anywhere)
Lesser Faydark (outside Mistmoore)
Feerott (outside Cazic Thule)
Innothule Swamp (outside Guk)

Not so likely:
Toxxulia (outside Paineel)
Erud's Crossing (at docks)
West Commons (outside Belfallen)
Everfrost (outside Permafrost)
