Islamic Interpretation of Dreams (Ibn-i Sirin):

(Labor pangs; Labor throes; Quake; Shaking; Shock) A tremor in a dream represents plants blooming, grass growing, vegetations sprouting, the blossoming of garden flowers, and the ripening of fruits.

If a pregnant woman sees an earth tremor in her dream, it represents labor throes.
