  1. Earthquake Albanov Artem 8 class

  2. Content What is an earthquake? What is the hypocenter and epicenter? Seismograph. Mercan scale (MSK-86). Illustrate the effects of earthquakes. The effects of earthquakes. Signs of an approaching earthquake. Rules of safe behavior during an earthquake. Questions on the topic. Literature.

  3. Earthquake - is it's tremors and fluctuations in the Earth surfaces arising as a result of the displacement and breaks in the earth's crust or upper mantle of the Earth and transmitted over long distances in the form of elastic waves.

  4. The center of earthquake The earthquake, that is, point under the ground, which is the source of an earthquake is called the hypocenter. Just above the hypocenter on the surface of the earth is the epicenter of the earthquake, which is located around the area experiencing the greatest fluctuations of soil.

  5. Seismograph . this is a sensitive instrument that detects and records the tremors, said their strength, direction, and duration of

  6. Depending on the intensity of the ground motion at the surface of the earth quake are divided by an international 12-point scale MSK-86 (scale commer). Typical manifestations earthquake The maximum intensity for Mercan, the scores 1-2 The population does not feel the earthquake 3 Some people feel the Earthquake, no damage 4-5 The earthquake was felt most people, no damage to buildings 6-7 Slight damage to buildings: the cracks in the walls and chimneys 7-8 Moderate damage to buildings: through cracks in the walls of the weak 9-10 11-12 General and almost total destruction of Larger lesions: the collapse of buildings of poor quality of construction, cracks in solid buildings

  7. Aftermath of the earthquake

  8. Aftermath of the earthquake Geological hazards. Tsunamis, floods. Fires. Panic. Injury and loss of life. Damage and destruction of buildings. Emissions of radioactive and hazardous chemical emergency, and other harmful substances. Transport accidents and catastrophes. Disruption of life support systems.

  9. Signs of impending earthquakes The smell of gas in areas where it had not previously mentioned. Outbreaks in the form of scattered light lightning. Sparking closely spaced, but not in contact, electrical wires. Bluish glow of the interior walls of houses. The unusual behavior of animals.

  10. Rules of safe behavior during an earthquake Do not panic. Protect yourself from debris, glass, heavy objects. Located on the 1st floor quickly leave the building and move away from him into the open. Located on the 2nd floor and above to take the safest place (away from windows, openings in the internal walls of the capital, in doorways, in the toilets).

  11. The end Thank you for your attention
