Main Body
Tsunamis are water waves of very large wave length which hits the coastal areas & causes large scale damage.
Causes of Tsunami:
1Earthquake: at tectonic boundaries solar lots of energy can translate into water waves.
2Shift in water volume: due to faulting water may get into Subduction Zone & can cause upward force which generate waves.
3Movement of tectonic plates e.g. Convergent boundary during 2004 Indian Ocean tsunami.
Impact on Coastal areas:
Flooding with huge waves
Property damage e.g. rail infra.
Loss of human life
Displacement of coastal community
Disruption of mangrove forest affecting fishing & navigation
Measures to be taken:
Pre-Tsunami: Hazard mapping, awareness campaign, alerting NDRF team, readying goods of urgent need
During Tsunami: Protection in shelter homes, advisory for steps to be followed by people
After Tsunami: RehabilitationEconomic, political
