The Great Earthshake (as called by the dinosaurs) was a huge earthquake taking place near the start of The Land Before Time. According to the Narrator it was created by two continents coliding. It took place at dawn and separated and killed many herds, including the main character's. It created a huge crack called the Great Divide, leading down to the "Big Underground". Many dinosaurs fell down the cracks, among them Sharptooth. Littlefoot and Cera nearly fell as well but Littlefoot's Mother saved them. There was also a stampede of Apatosaurus, Triceratops, Saurolophus, Parasaurolophus, Pteranodon, Dimorphodon, Struthiomimus, Edaphosaurus, Compsognathus and Coelophysis.

Other earth shakes include the Flying Rocks from The Land Before Time III: The Time of the Great Giving and the Three horn peak when it turns red and have lava from The Land Before Time VII: The Stone of Cold Fire.
