Do you know what tsunamis are?How they are formed? How they canbe predicted and how you can saveyourself if you are residing in any ofthe coastal districts of the state?

What is disaster management?

Disaster management covers the rangeof activities designed to maintain controlover disasters/ emergency situations and toprovide a framework for helping people toavoid, reduce the effects of, or recoverfrom impact of a disaster. These activitiesmay be related to preparedness, mitigation,emergency response, relief and recovery

TSUNAMI

The term “Tsunami” has been coinedfrom Japanese words ‘tsu’ meaning harbourand ‘name’ meaning waves. Tsunamis arehuge waves generated by earthquakes,volcanic eruptions, or under waterlandslides which devastate coastalcommunities.

Tsunamis caused by nearbyearthquakes may reach the coast withinminutes. When the waves enter shallowwater, they may rise to several feet or, inrare cases, tens of feet, striking the coastwith devastating force. The tsunami dangerperiod can continue for many hours after amajor earthquake.

What to do BEFORE Tsunami?

Find out if your home, school, work place, or other frequently visited locations are intsunami hazard prone areas. Plan evacuation routes from your home, school, work place or any other place youcould be where tsunamis present a risk.Practice your evacuation routes.Have disaster supplies on hand.Discuss tsunamis with your family.

Detecting Tsunamis

With the use of satellite technologyit is possible to provide nearlyimmediate warning of potentiallytsuna-migenic earthquakes. Warningtime depends upon the distance of theepicenter from the coast line. Thewarning includes predicted times atselected coastal communities where thetsunami could travel in a few hours.

Coastal tidal gauges can stoptsunamis close to the shore, but they areuseless in deep oceans. Tsunamidetectors, linked to land by submarinecables, are deployed 50 odd kms out atsea. ‘Tsunameters’ transmit warnings ofbuoys on the sea surface, which relay itto satellites.
