  7. What usually happens • During a landslide there are some things that always happen • The land tends to fold up first • Then is starts to fall • It can happen slowly or very fast • There are 4 kinds of landslides • Mudflow , slump, debris flow, and rockslide

  8. Here is a picture of the different kinds of landslides

  9. Worst case scenario for a landslide • The most extreme conditions would be… • The whole side of the mountain collapses • It moves faster than a car • The width of it is bigger than 3 cars

  10. How landslide are measured • Landslideshavenoofficial scale so they are measured by… • How many metric tons fell • How deep they are • How far they traveled

  11. After affects of a landslide • Tsunamis (if it falls in a lake) • The hill may be completely destroyed • It will wipe out any forest nearby • It could break a dam causing floods

  12. Key terms • a metric ton = 2204.62262 • A tsunami is a giant wave • Mudflow: a landslide made of mud • Slump: when it all falls at once • Debris flow: made of gravel, wood, or anything that’s not dirt or rock • Rock fall: rocks falling at high speeds

  13. Here is a video of a landslide
