  1. Catastrophic events

  2. Any natural or man-made incident which results in extraordinary levels of mass casualties, damage, or disruption severely affecting the population, environment, and/or economy. What is a Catastrophic event?

  3. Can spread slowly or very fast; wind has the biggest impact Lightning strikes cause 1 out of every 5 wildfires Drought, wind, high temps. & low humidity help them spread wildfires

  4. Millions of acres of forest can be destroyed • Animals may become endangered due to habitat destruction • Economic losses can impact humans Wildfires, cont.

  5. Winds blow in a spiral around a calm center called an eye • May last a week or more • Forms from a tropical storm over the Atlantic Ocean, Caribbean Sea, or Gulf of Mexico hurricanes

  6. An unusually long period of dry weather that lasts long enough to cause water supply shortages Lack of adequate precipitation for 2+ years can become a drought Crop failure, livestock death, increased forest fires, and water shortages drought

  7. A vent in the Earth which allows magma to escape to the surface When pressure from gases within the magma become too great, an eruption occurs Searing hot poisonous gases, lava flows, flash flooding, and tsunamis volcano

  8. Can affect breathing, contaminate water supplies, collapse roofs, disrupt machinery, and cause jet engines to fail while flying Volcano, continued

  9. Violently rotating column of air extending from a thunderstorm down to the ground Associated with strong, frontal systems that form in the Central States and move east Can destroy buildings and vehicles, uproot trees tornado

  10. A series of waves that can travel between 450-600 mph in the open ocean Ocean waves produced by earthquakes, volcanic eruptions, meteorite impact, or underwater landslides tsunamis

  11. Can occur during any season and any time of day or night • Impact includes drowning, flooding, contamination of drinking water, loss of habitat or human homes Tsunamis, continued

  12. The vibration of the Earth’s surface that occurs after a release of energy in the crust • Occurs where two tectonic plates collide • Can cause landslides, avalanches, fires, tsunamis, property damage, and loss of life earthquake

  13. An overflowing of water onto land that is normally dry Caused by intense or long term precipitation, hurricane storm surges, or melting snow flood

  14. Humans have altered the landscape in several ways~paving the ground for housing, roads, and parking lots • Can cause loss of life, disease, property loss or damage, contamination of drinking water, destruction of crops and livestock Flood, continued
