Geology Volcanoes&Earthquake Assignment21 - Assignment drillBecause of this, the P-wave shadow zone occurs and seismometers do not record the initial waves.9. Magnitude refers to the measurement of the energy that an temblor releases and it may be given through Ritcher scale. The lowest scale is 2.5 or less, which is normally not felt, entirely is recorded by a seismograph. Scale of 2.5 to 5.4 means minor aggrieve and can be felt most of the time. Scale of 5.5 to 6.0 will cause damage to structures while scale of 6.1 to 6.9 will cause damage in an area with heavy population. Major earthquakes record scales of 7.0 to 7.9 while a magnitude of 8.0 or high can destroy an entire community located near the epicenter.10. The intensity of an earthquake means a measure of the earthquakes power of shaking. The intensity is measured by the Mercalli scale that represents the damage or effect that the earthquake causes. Intensity can range from I to XII given in papistic numerals.11. Inten sity of an earthquake varies for various reasons. It decreases with distance of the earthquake. Intensity also depends on the shape of the building, foundation, or temper of construction. Intensity also varies depending on the near surface or regional geologic conditions.20. Vertical excretion refers to a method of evacuation preferred for helping people out of the area affected by an earthquake or Tsunami. It involves structures that resemble artificial hills such as a ramp or a radio beacon. A vertical evacuation used in the case of a Tsunami allows the waves to pass through the lighthouse or ramp while victims seek refuge in top floors.21.
