  1. Disaster Planning • A system of comprehensive systems management (CEM) is essential to ensure that everyone knows his or her role when disaster strikes; it means that all levels of government and the private sector coordinate their efforts to manage a disaster.

  2. Disaster Planning • Emergency Management encompasses four phases: • Hazard reduction • Preparedness • Response • Recovery

  3. Hazard Reduction • Probability: the likelihood of a recurring disaster • Vulnerability: the scope of damage to persons or property • Site zoning: reducing the impact of a potential disaster by locating hazards to less populated areas

  4. Preparedness • These activities generally refer to identifying an organizing resources available both from inside and outside a locality. • What will need to be done? • Who will be responsible?

  5. Response • Planning for role responsibility and additional resource allocation is vital. • Triage is a method used to determine which victims need immediate medical attention and which victims can tolerate a delay in treatment. • During emergencies, an Emergency Operations Center (EOC) must be established.

  6. Recovery • The “return to normal” also involves planning to ensure an adequate restoration of homes, businesses, and public facilities and rejuvenation of the economy and social structure of the community. • Reassessment of risk reduction by officials is also essential.

  7. Flooding happens during heavy rains, when rivers overflow, when ocean waves come onshore, when snow melts too fast or when dams or levees break. Flooding may be only a few inches of water or it may cover a house to the rooftop. Floods that happen very quickly are called flashfloods. • Flooding is the most common of all natural hazards. It can happen in every U.S. state and territory.

  8. Important terms • Flood Watch or Flashflood Watch -- Flooding may happen soon. Stay tuned to the radio or television news for more information. If you hear a flashflood warning, talk to an adult immediately! • Flood Warning -- You may be asked to leave the area. A flood may be happening or will be very soon. Tell an adult if you hear a flood warning. If you have to leave the area, remember to bring your Disaster Supply Kit and make arrangements for your pets. • Flashflood Warning -- A flashflood is happening. Get to high ground right away.

  9. A tsunami (pronounced soo-nahm-ee) is a series of huge waves that happen after an undersea disturbance, such as an earthquake or volcano eruption. (Tsunami is from the Japanese word for harbor wave.) The waves travel in all directions from the area of disturbance, much like the ripples that happen after throwing a rock. The waves may travel in the open sea as fast as 450 miles per hour. As the big waves approach shallow waters along the coast they grow to a great height and smash into the shore. They can be as high as 100 feet. They can cause a lot of destruction on the shore. They are sometimes mistakenly called "tidal waves," but tsunami have nothing to do with the tides.

  10. While thunder won't hurt you - lightning will! So it's important to pay attention when you hear thunder. Thunderstorms happen in every state and every thunderstorm has lightning. Lightning can strike people and buildings and is very dangerous. • Thunderstorms affect small areas when compared with hurricanes and winter storms. The typical thunderstorm is 15 miles in diameter and lasts an average of 30 minutes. Nearly 1,800 thunderstorms are happening at any moment around the world.

  11. Despite their small size, all thunderstorms are dangerous. Every thunderstorm produces lightning, which kills more people each year than tornadoes. Heavy rain from thunderstorms can lead to flash flooding. Strong winds, hail, and tornadoes are also dangers associated with some thunderstorms. • You can estimate how many miles away a storm is by counting the number of seconds between the flash of lightning and the clap of thunder. Divide the number of seconds by five to get the distance in miles. The lightning is seen before the thunder is heard because light travels faster than sound. (Of course, get safe shelter first, before you take the time to count the seconds!) • Thunderstorms need three things: • Moisture - to form clouds and rain. • Unstable Air - relatively warm air that can rise rapidly. • Lift - fronts, sea breezes and mountains are capable of lifting air to help form thunderstorms.

  12. Thunderstorms are most likely to occur in the spring and summer months and during the afternoon and evening hours but they can occur year-round and at all hours of the day or night. Along the Gulf Coast and across the southeastern and western states, most thunderstorms occur during the afternoon. Thunderstorms often occur in the late afternoon and at night in the Plains states. Thunder and lightning can sometimes even come with snowstorm! During the blizzard of March 1993, lightning resulted in power outages near Washington, D.C.

  13. A volcano is a mountain that opens downward to a pool of molten rock below the surface of the earth. When pressure builds up, eruptions occur. Gases and rock shoot up through the opening and spill over or fill the air with lava fragments. Eruptions can cause lateral blasts, lava flows, hot ash flows, mudslides, avalanches, falling ash and floods. Volcano eruptions have been known to knock down entire forests. An erupting volcano can trigger tsunamis, flashfloods, earthquakes, mudflows and rockfalls. • Active volcanoes in the U.S. are found mainly in Hawaii, Alaska, California, Oregon and Washington. The greatest chance of eruptions near areas where many people live is in Hawaii and Alaska. The danger area around a volcano covers about a 20-mile radius. In May 18, 1980, Mount St. Helens erupted in Washington state. It killed 58 people and caused more than $1 billion in property damage. • Fresh volcanic ash, made of pulverized rock, can be harsh, acidic, gritty, glassy and smelly. The ash can cause damage to the lungs of older people, babies and people with respiratory problems.

  14. Earthquakes are the shaking, rolling or sudden shock of the earth’s surface. Earthquakes happen along "fault lines" in the earth’s crust. Earthquakes can be felt over large areas although they usually last less than one minute. Earthquakes cannot be predicted -- although scientists are working on it! • Most of the time, you will notice an earthquake by the gentle shaking of the ground. You may notice hanging plants swaying or objects wobbling on shelves. Sometimes you may hear a low rumbling noise or feel a sharp jolt. A survivor of the 1906 earthquake in San Francisco said the sensation was like riding a bicycle down a long flight of stairs.

  15. Earthquake intensity of an earthquake can be measured. One measurement is called the Richter scale. Earthquakes below 4.0 on the Richter scale usually do not cause damage, and earthquakes below 2.0 usually can’t be felt. Earthquakes over 5.0 on the scale can cause damage. A magnitude 6.0 earthquake is considered strong and a magnitude 7.0 is a major earthquake. The Northridge Earthquake, which hit Southern California in 1994, was magnitude 6.7. • Earthquakes are sometimes called temblors, quakes, shakers or seismic activity. The most important thing to remember during an earthquake is to DROP, COVER and HOLD ON. So remember to DROP to the floor and get under something for COVER and HOLD ON during the shaking.

  16. Hurricanes are severe tropical storms that form in the southern Atlantic Ocean, Caribbean Sea, Gulf of Mexico, and in the eastern Pacific Ocean. Hurricanes gather heat and energy through contact with warm ocean waters. Evaporation from the seawater increases their power. • Hurricanes rotate in a counter-clockwise direction around an "eye." Hurricanes have winds at least 74 miles per hour. When they come onto land, the heavy rain, strong winds and heavy waves can damage buildings, trees and cars. The heavy waves are called a storm surge. Storm surges are very dangerous and a major reason why you MUST stay away from the ocean during a hurricane warning or hurricane.

  17. Tornadoes are nature’s most violent storms. Tornadoes must always be taken seriously. Tornadoes can be very dangerous -- sometimes even deadly. They come from powerful thunderstorms and appear as rotating, funnel-shaped clouds. Tornado winds can reach 300 miles per hour. They cause damage when they touch down on the ground. They can damage an area one mile wide and 50 miles long. Every state is at some risk, but states in "Tornado Alley" have the highest risk. Tornadoes can form any time of the year, but the season runs from March to August. The ability to predict tornadoes is limited. Usually a community will have at least a few minutes warning. The most important thing to do is TAKE SHELTER when a tornado is nearby.

  18. Important Terms: • Tornado Watch -- Tornadoes are possible. Stay tuned to the radio or television news. • Tornado Warning -- A tornado has been sighted. Take shelter immediately!

  19. It is very important to prepare for both building fires and wild fires. Fires in buildings are very dangerous. Every year, about 5,000 people in this country are killed by building fires. FEMA has a Web site dedicated to teaching kids what to do about building fires. Look for the fire extinguisher at the bottom of the page to visit that Web site. • One of the most important things to remember is that your house should have a working smoke detector. Look around your house to see if you have a smoke detector on every floor in the house. Get help from a parent or adult to check if your smoke detectors are working. Check also to see if your family has a working fire extinguisher.

  20. Your family should have a fire plan of how to escape from your house if it is on fire. If you are caught in a fire REMEMBER, stay low to the ground where the smoke is not so heavy. NEVER hide during a fire. Always get out. And once you are out, stay out. DO NOT go back for a toy. Tell an adult if there is a person left behind in the burning house. • Wildfires are a danger for people who live in forest, prairies or wooded areas. These fires are sometimes started by lightning or by accident. They can move very fast and burn many acres. Remember, if there is a wildfire near you and your family is told to evacuate -- go right away! And remember to bring your pets with you!

  21. In many areas of the country, winters bring heavy snowfall and very cold temperatures. Heavy snow can block roads and cause power lines to fall down. The cold temperatures can be dangerous if you are not dressed correctly.

  22. Important Terms: • Freezing rain: Rain that freezes when it hits the ground, creating a coating of ice on roads and walkways. • Sleet: Rain that turns to ice pellets before reaching the ground. Sleet also causes roads to freeze and become slippery. • Winter Weather Advisory: Cold, ice and snow are expected. • Winter Storm Watch: Severe weather such as heavy snow or ice is possible in the next day or two. • Winter Storm Warning: Severe winter conditions have begun or will begin very soon. • Blizzard Warning: Heavy snow and strong winds will produce a blinding snow, near zero visibility, deep drifts and life-threatening wind chill. • Frost/Freeze Warning: Below freezing temperatures are expected.
