Constructive effects of earthquakes are:

• Release of energy: Earthquakes help the Earth to release its energy.
• Formation of land forms: As a result of earthquakes, many landforms are built. It also results in the changing of the coastline. Earthquakes in the Himalayan region have resulted in the formation of various lakes. Further, the formation of bays, estuaries and gulfs has resulted in better navigation.
