According to WMO(World Meteorological Organization)- “Tsunami is a series of waves generated in a body of water by the displacement of large volume of water, usually as a result of earthquakes, landslides or volcanic eruptions”.
Formation of Tsunami –
- Displacement of water through earthquake, landslides, volcanic eruptions or meteorites.
- Transfer of energy to the surrounding water.
- Wave formation and wave propagation at speed of upto 500 mph .
- Shoaling and amplification of waves led to pile up of water and increase in height near the coast.
- Tsunami waves reaches the coast causing widespread destruction and loss of life.
Tsunami preparedness involves –
- Preparedness and planning measures taken before a disaster strikes to minimize it’s impact ex-public education and mass awareness.
- Timely and accurate information to prevent and mitigate the impact of disasters.
- Emergency Response planning for unexpected events.
- Safe and orderly exit of the people.
- Recovery and rehabilitation efforts after the disaster.
- International cooperation for better management
- Technological Advancements enhance preparedness, response and recovery.
Mitigation Efforts taken by the governments –
- Creation of institutional framework like NDMA,INCOIS,IMD,NCMRWF.
- Coastal radar and surveillance system for early warning system.
- Tsunami resistant construction at Andaman and Nicobar islands .
- Regulatory measures like Disaster Management Act 2005 , Coastal Regulation Zone etc .
- Creation of Intergovernmental Oceanographic Commission (IOC),Sendai framework for Disaster Risk Reduction 2005 etc to promote international cooperation .
- Formation of National Disaster Response Force (NDRF).
