Tsunamis are triggered by underwater earthquakes or volcanic eruptions, displacing water and creating massive waves. Coastal areas can be protected using early warning systems to enable timely evacuations.

Class 6 Social Science Chapter 2 Oceans and Continents question answer
Tsunamis are large, powerful waves formed when underwater earthquakes, volcanic eruptions, or landslides displace huge volumes of ocean water. The energy released from these geological events travels through the water, generating waves that increase in height as they approach shallow coastal areas. Upon reaching shore, these waves can cause devastating flooding, destruction, and loss of life.
One effective way to protect coastal areas is by implementing an early warning system. This system uses seismic data, satellite technology, and ocean buoys to detect unusual ocean movements. Once a potential tsunami is detected, alerts are issued to affected regions, allowing people to evacuate to safer, elevated areas. Such systems have been established in tsunami-prone regions, including the Indian Ocean, where India contributes to the Indian Ocean Tsunami Warning System. By providing timely warnings, these systems save lives and reduce property damage.
