Project File On Generating Awareness On Disaster Management

ADVERTISEMENTS:4.CyclonesEntire 5700 km long coastline of Southern Peninsular India covering 9 states105.LandslidesEntire Sub-Himalayan Regions and Western Ghats10Major such disasters include a devastating earthquake which hit Bhuj Town in Gujarat caused massive damage. Earth-quake generated water waves called Tsunamis caused tremendous damage in Tamil Nadu and Kerala. Types of Disasters:There are two types of disasters:(i) Natural Disasters:The disasters that are caused by nature are termed as natural disasters e.g., earthquake, cyclone etc.(ii) Man-made Disaster:The disasters which are caused as a result of human activities are termed as Man-Made Disasters e.g., Road accident, terrorist attack. ADVERTISEMENTS:Natural Disasters:1.

Earthquake:Earthquake is a sudden and violent shaking of ground causing great destruction as a result of movement of earth’s crust. An earthquake has the potential to tsunami or volcanic eruption.Earthquake of magnitude 9.2 on the Richter’s scale in 2004 in Indonesia is the second largest earthquake ever recorded.

The deadliest earthquake happened in Central China, killing over 800,000 in 1556. People during that time and region lived in caves and died from the caves collapsing.

ADVERTISEMENTS:Earthquake mitigation strategies:a. Existing critical facilities built on reclaimed land should be inspected and retrofitted if necessary to ensure earthquake resistance.b.

Future critical facilities should not be located on reclaimed land because of the high potential for liquefaction.c. Older unreinforced masonry buildings should be inspected and retrofitted if necessary to increase earthquake resistance.d. Older unreinforced masonry buildings should not be used for critical functions.2. Cyclone:Cyclones (or more properly called Tropical Cyclones) are a type of severe spinning storm that occurs over the ocean near the tropics.The most famous Australian historic cyclone was Cyclone Tracy, December 1974, where around 11 people died in Darwin, Northern Territory. The direction they spin depends on which hemisphere they are in. In the Southern hemisphere they spin in a clockwise direction and Northern hemisphere they spin in an anti-clockwise direction.Cyclone mitigation strategies:a. Future critical facilities should not be located in areas of accelerated winds.b.

The most significant aspect of structural damage to buildings by high velocity wind results from roof damage. The roofs of existing buildings should be inspected and if necessary retrofitted to adequate standards.c. The roofs of existing critical facilities should be retrofitted to a higher standard to ensure wind resistance.d. Building openings such as windows and doors also suffer damage from high velocity winds.

These openings if not constructed of wood or metal should be protected with shutters or temporary covers of adequate design.Table. Classification of cyclone based on speedCategoryStrongest Guse (Km/h)Typical Effects (Indication Only)1 (Tropical Cyclone)Less than 125 (Gales)Negligible house damage. Damage to some crops, trees and caravans. Craft may drag moorings.2 (Tropical Cyclone)125-169 (Destructive winds)Minor house damage, Significant damage to signs, trees and caravans, Heavy damage to some crops. Risk of power failure. Small craft may break moorings.3(Srvere Tropical Cyclone e.g., Roma)170-224 (Very destructive winds)Some roof and structural damage.

Some caravans destroyed. Power failure likely.4(Srvere Tropical Cyclone e.g., Tracy)225-279 (Very destructive winds)Significant roofing loss and structural damage. Many caravans destroyed and blown away. Dangerous airborne debris.

Widespread power failures5(Srvere Tropical Cyclone e.g., Vance)More than ‘280 (Very destructive winds)Extremely dangerous with widespread destruction.3. Tsunami:Tsunamis are giant waves, initiated by a sudden change, usually in relative position of underwater tectonic plates.

The sudden jerk is enough to propagate the wave; however, its power can be enhanced and fed by lunar positioning and boundaries that focus its energy.Tsunami mitigation strategies:a. In some tsunami-prone countries earthquake engineering measures have been taken to reduce the damage caused onshore.b. Japan, where tsunami science and response measures first began following a disaster in 1896, has produced ever-more elaborate countermeasures and response plans. That country has built many tsunami walls of up to 4.5 metres (15 ft) to protect populated coastal areas.c.

Other localities have built floodgates and channels to redirect the water from incoming tsunami.4. Volcanic eruptions:Volcanic disasters are caused by lava flows, volcanic mudflows and pyroclastic flows triggered by volcanic activities such as eruptions. It covers extensive areas; volcanic disasters can cause a large-scale damages and serious personal injury. Secondary disasters such as debris flows are often triggered by rainfall after a volcanic eruption.In the 1815, the Indonesian eruption threw rocks more than 100 cubic km of ash killing 92,000 people. The greatest volcanic explosion occurred in Indonesia in 1883, which resulting in rocks hurling 55 km up into the air.

The explosion was heard in Australia and generated a 40 m high tsunami, killing 36,000 people.Volcanic disasters mitigation strategies:a. Learn about community warning systems and of disasters that can come from volcanoes (earthquakes, flooding, landslides, mudflows, thunderstorms, tsunamis)b. Make evacuation plans to higher ground with a backup route.c. Have disaster supplies on hand (flashlight, extra batteries, portable battery-operated radio, first aid kit, emergency food and water, nonelectric can opener, cash and credit cards, and sturdy shoes)5. Floods:Flooding is the unusual presence of water on land to a depth which affects normal activities. Flooding can arise from: overflowing rivers (river flooding), heavy rainfall over a short duration (flash floods), or an unusual inflow of sea water onto land (ocean flooding).

Ocean flooding can be caused by storms such as hurricanes (storm surge), high tides (tidal flooding), seismic events (tsunami) or large landslides.Flood mitigation strategies:a. Watercourses which pass through significant settlement areas should be properly configured and lined with concrete.b. Existing bridges should be inspected to determine which ones are too low or which have support pillars within the watercourse channel. Where possible these should be replaced as these features restrict water flow and cause the channels to be easily blocked with debris.c. Future bridges should not be built with these undesirable features.d.

Buildings constructed adjacent to watercourses should be elevated by at least one meter to prevent potential flood inundation.e. Critical facilities should not be located adjacent to watercourses. Man-made Disasters:1. Road Accidents:Road accidents are common in India due to reckless driving, untrained drivers and poor maintenance of roads and vehicles. According to Lifeline Foundation, the Ahmedabad based organization working for road safety, India accounts for 13 per cent of road accident fatalities worldwide.With 130,000 deaths in 2007, India tops in the number of people killed in road accidents, surpassing China’s 90,000. Most of these deaths occurred due to bad road designs and lack of proper traffic management systems to separate different streams of traffic.2. Building and Bridge Collapse:Building collapses are frequent in India where construction is often hastily done, with little regard for safety regulations, particularly in the western part of the country.3.

Terrorist Attack:Devastating acts such as the terrorist attacks on the World Trade Centre and the Pentagon have left many concerned about the possibility of future incidents in the United States and their potential impact. Terrorism may involve devastating acts using weapons of mass destruction ranging from chemical agents, biological hazards, a radiological or nuclear device, and other explosives.Mitigation strategies for man-made disasters:a. For road accidents, traffic rules and regulations need to be followed strictly.b. For building and bridge collapse, standard building materials should be used.c. Moreover, more and more public awareness should be made to minimize the effects of man-made disasters.If a Terrorism-Related Event Happens:a.

Stay calm and be patient.b. Listen to a local radio or television station for news and follow the instructions of emergency service personnel.c. If the incident occurs near you, look out for secondary hazards such as falling debris or additional attacks.d. Check for injuries and summon help for seriously injured people. Awareness through Mass Media:a.

Media plays a significant role in educating the population about disaster and its management.b. Without media we could not aware people about disaster in remote areas of the country. Central Sector Scheme for Disaster Management:a. Human resource Developmentb. Setting up of National Centre for Disaster Management (NCDM)c. Setting up of Disaster Management Faculties in Statesd. UNDP is a united nation’s global development programs working in 166 countries.e.
