• Earthquake


  • During in cartqake, the strongest sheking
  • The epicor Sometimes, the ground surface breaks along the
  • Tek These are also times the movement is deep underground and the surface does not break
• Magnitude


  Measures the gy being released from the origin of the earthquake, measured by an intent called seismograph
• Richter Magnitude Scale


  Means the quantity of seismic energy released by an earthquake
• Intensity


  Strength of the trembling made by the earthquake at a place varies relying on where you are and is determined by the Mercalli Scale
• Active faults


  • Areas along in which displacement is expected to occur. Since a shallow earthquake prodanes displacement across a fast, all shallow carthquakes occur on active fals. These are considered to be geologic hands
• Inactive faults


  • Areas that can be identified, but which do net lave earthquakes
• VARIOUS POTENTIAL EARTHQUAKE HAZARDS

  • Ground Shaking
  • Ground Rupture
  • Liquefaction
  • Ground Subsidence
  • Tsunami
  • Landslide
  • Fire
• Ground Shaking


  Vibration of the grand daring an cardspake; can abe trigger the other hazards such as ligation and landslides; caused by faulting during an sathyake which releases the esegy that had bem built up by the application off stress to the lithosphere
• Ground Rupture


  Effect of the ground, happened when fut napare from the focus extends to the earth's surfaces. Structures that span a surface frakt are likely to suffer great damage, avoid building across, or even near these hands
• Liquefaction


  Happened when the sand or wil and groundwa misad during the suking of moderate to strong earthqa the ground becomes very sh and acts similar to quicksand can undermine the foundations and supports of buildings, bridges, pipelines, and rocks, causing them to sink into the ground, collapse, or dissolve
• Ground Subsidence


  The sinking or setting of the grand surface; can result bon the settlement of native low-density xils, or the caving in of natural or man-made underground vaids movements that occurs along faults can be horizeral or vertical or have a competent of both, as a result, a large area of land can sabide drastically during an earthquake
• Tsunami


  Series of giant sea waves generated by an carthquake with a magnitude of 7.0
• Landslide


  Movement of rock, debris, or earth down slopes plate tectonics move the soil that covers them moves with it, when an earthquake occur on areas with steep slopes, many times the soil slips causing landdides
• Tsunami


  Series of giant sea wavesc generated any strong carthquakes and massive volcanic eruptions; can cause flooding which can extend inland by a thousand ft or mores. One of the most feared natural disasters
• Deadliest Indian Ocean (Sumatra, Indonesis) in 2004 with 350,000 casualties
• Recognizing Tsunami

  • Feel: Earthquake with magnitude>7.0 (carthquake can displace, creating pressure in the water above it); severe shaking of the ground
  • See: Lowering of the sea level
  • Hear: Roaring sound like a minor area casing
• Ground Shaking


  • Can cause ehject in a bildgal ul
  • When the avarity of the god shaking incrises, it can ese duge to the or even can cause collapsing in sigen Spefaction or landlides

• Ground Subsidence

• Tsunami


  Can destroy beans, aproct trees, devaste nearby properties. and drows and kill people and animals. Can cause flooding which can estand island by a thousand f
• Flood


  Can also be caused by overflowing of water from dans servals or river (earthquake can beuk dams and ripops of rivers causing the waker to overflow and flood the area)
• Landslide


  During earthquakes, rocks and soil rapidly roll along sp sloped the falling rocks may hit people, houses or vehicles causing accidents
• Fire


  Carissake can overturn electrical posts, break power lines and gas lines which usually starts fire causing great loss in properties and lives
