  2. Need to know vocabulary • Magnitude- measure of energy realized during an earth quake. • Liquefaction- occurs when wet soil acts more like a liquid during an earthquake. • Tsunami- seismic sea wave that begins over an earthquake focus and can be highly destructive when reaches the shore.

  3. Tsunami’s • -Tsunami: Seismic sea wave that begins over an earthquake focus and can be highly destructive when reaches the shore. • -Focus: The point were energy release first occurs is the Focus of an earthquake. • -An earthquake under the ocean causes a sudden movement under the ocean floor. • -Tsunamis are often barely visible when they are in the deep sea (about 1 km high) this makes them hard to see until they approach shore , that’s when they begin to reach about 30 km eight and become very visible. • - Tsunamis travel fast but not at infinite speed. • -An earthquake usually has to have a magnitude of about 6.75 (on the Richter scale) for it to create a tsunami.

  4. Tools used to measuring earthquake magnitude • The Richter magnitude scale is used to describe the strength of an earthquake and is based on the height of the lines on a seismograph. • - The Mercalli scale describes the intensity of the earth quake and the damage it causes. • - seismograph: Seismic waves from earthquakes are measured with an instrument known as a seismograph.

  5. Before/During After • -First you want to make sure that any electrical things dealing with gases or water are turned off. • -If you are indoors then stay away from objects that could possible brake or fall on you during an earthquake, such as windows. • -Try to find shelter under a desk or a solid door way that is sturdy enough to not collapse because of the vibrations of the earthquake. • -If you are out doors then stay out in the open, avoid falling power lines, chimneys , or any other parts of a building that might fall/ collapse. • -Shut off any damaged gas or water lines immediately. • *If you can smell gas this means there has been a gas leek, immediately exit the building and call the authorities to alert them about the leek. • -Avoid damaged buildings. • -Be careful around glass or ruble and make sure to wear boots to protect your feet from getting cuts. • -Stay far away from any beaches , Tsunamis some times hit after the ground has stopped shaking. Preparation for an earthquake/during an earthquake After an earthquake

  6. 1.)If you smell a gas leak after an earthquake do you want to? A-Try to find the location of the smell B-evacuate the building and alert the authorities C-turn off the gas and remain in the building Test question #1 Correct answer … B evacuate the building and alert the authorities
