CYCLONE

AN EARTHQUAKE IS A PHENOMENON THAT OCCURS WITHOUT WARNING AND INVOLVES VIOLENT SHAKING OF THE GROUND AND EVERYTHING OVER IT.

MANAGEMENT OF EARTHQUAKE

Pre-management Post-management.

PRE-MANAGEMENT OF EARTHQUAKE:-

This management is related to preparedness factor. To safeguard your house, check in which seismic zone your house is existing.

HAITI EARTHQUAKE

2)POST MANAGEMENT OF EARTHQUAKE:-

In post management, we are considering the precautions to be taken during and after the earthquake.By using GIS & GPS system impact of earthquake can be calculated.

EARTHQUAKE IMPACT

DURING THE EARTHQUAKE

Take cover. Go under a table or other sturdy furniture; kneel, sit, or stay close to the floor. Hold on to furniture legs for balance. Be prepared to move if your cover moves.

Ref.: Haiti earthquake,2010

IF OUTDOORS:-

Move into the open, away frombuildings, street lights, and utility wires. Once in the open, stay there until the shaking stops.

DAMAGE OF TOWER IN EARTHQUAKE

AFTER EARTHQUAKE:-

If the building you live in is in a good shape after the earthquake, stay inside and listen for radio advises. If you are not certain about the damage to your building, evacuate carefully. Do not touch downed power line.

HAITI EARTHQUAKE

A massive 7.0-magnitude earthquake has struck the Caribbean nation of Haiti on 12 JAN,2010.The extent of the devastation is still unclear but there are fears thousands of people may have died. Haiti's worst quake in two centuries hit south of the capital Port-au-Prince on Tuesday, wrecking the presidential palace, UN HQ and other buildings. Haiti earthquake

CYCLONE

Cyclones caused due to atmospheric disturbances around a low-pressure area distinguished by swift and often destructive air circulation. They are usually accompanied by violent storms and bad weather. The air circulates inward in an anticlockwise direction in the northern hemisphere and clockwise in the southern hemisphere.

CYCLONE FORECASTING SYSTEM

Monitoring process has been revolutionized by the advent of remote sensing techniques. A TC intensity analysis and forecast scheme has been worked out using satellite image interpretation techniques which facilitate forecasting of storm surges. Satellite based observations are being extensively utilized

CYCLONE MANAGEMENT

Before cyclone season:-Prepare an emergency kit containing: A portable radio, torch and spare batteries; Stocks dry food – Chura, Chhatua, Mudhi, gur, etc. Matches, fuel lamp, portable stove, cooking utensils, waterproof bags A first aid kit, manual, etc. Trim dry tree branches, cut off the dead trees and clear the place/courtyard of all debris, including coconuts and tree branches.

UPON CYCLONE WARNING

Listen to your local radio / TV, local community warning system for further information. . Take special care for children, elders, sick, pregnant women and lactating mothers in your family. Do not forget your emergency food stock, water and other emergency items. Go to nearest cyclone shelter.Do not venture into the sea for fishing. CYCLONE VIEW FROM SATELITE AT

ON LOCAL EVACUATION

Lock your home, switch off power, gas, water, and take your emergency kit. If evacuating to a local shelter or higher grounds carry the emergency kit and minimum essential materials. Wear strong shoes or chappals and clothing for protection.

TROPICAL CYCLONE

ON CYCLONE STRIKING :-Disconnect all electrical appliances and turn off gas. If driving, stop – but well away from the sea and clear of trees, power lines and watercourses. Stay in the vehicle.

After the cyclone:-Check for gas leaks. Do not use electric appliances, if wet. Listen to local radio for official warnings and advice.

FLOOD

Floods are the most frequent natural disaster that India has to face almost every year. Flooding is caused by the inadequate capacity within the banks of rivers to contain the high flows brought down from the upper catchment due to heavy rainfall.

FLOOD FORECASTING

The Flood Forecasting involves the following four main activities:-(1) Observation and collection of hydrological and hydro-meteorological data;(2) Transmission of Data to Forecasting Centers;(3) Analysis of data and formulation of forecast; and(4) Dissemination of forecast.

Without management?

MANAGEMENT OF FLOOD

Flood management techniques can be divided into two types,1) Hard engineering option2) soft engineering option.

MANAGEMENT OF FLOOD

HARD ENGINEERING OPTION

1)Dam construction Dams are often built along the course of a river in order to control the amount of discharge. Water is held back by the dam and released in a controlled way.

2) River engineering The river channel may be widened or deepened allowing it to carry more water

Flood in eastern region

SOFT ENGINEERING OPTION

1)Afforestation:plant trees near the banks of river. 2)Managed flooding: The river is allowed to flood naturally in places, to prevent flooding in other areas-for example, near settlements. 3) Planning:

planning of societies should be away from the floodplain.

Afforestration

PRECAUTION FOR FLOOD

BEFORE THE FLOOD:-Have an emergency kit on hand which includes a: A portable radio, torch and spare batteries; Stocks of fresh water, dry food (chura, mudi, gur, biscuits), etc.

FLOOD IN BIHAR

ON WARNING:-Tune to your local radio/TV for warnings and advice. Keep dry food, drinking water and clothes ready

During floods:-Drink boiled water. Do not let children remain on empty stomach.

Rescue action during flood

DROUGHT Droughts in the Indian region are mainly due to various kinds of failures of rains from southwest monsoon. Rainfall is the ultimate source of water, affecting production of crops and other biomass by direct falling on the fields as well as supporting surface and ground water irrigation.

TSUNAMI

Tsunamis can be generated when the sea floor abruptly deforms and vertically displaces the overlying water. When large areas of the sea floor elevate or subside, a tsunami can be created.

TSUNAMI MANAGEMENT

It suggested setting up of a National Disaster Management Authority under the Union Home Ministry which had set up an emergency control room. It also kept in constant touch and coordinated with the three wings — Army, Navy and Air Force – were participating in relief and rescue measures in a big way, flying sorties and shipping tonnes of relief material.

CONCLUSION

1) Disaster management decreases the destruction ability of disaster. 2) Disaster management makes us able to face the disasters. 3) Disaster management safeguard to human beings. 4)The awareness about disaster management is needed.
