1.Tectonic Movements:
2.Volcanic Eruptions:
3.Other Reasons:
The roofs of underground caves sometimes give way and release great force to cause minor tremors in the earth crust. Nuclear explosions also release massive energy to cause tremors in the earth crust.

2.Loss of Life:
3.Changes in the course of rivers:
4.Tsunamis:
