What are some factors that affect the amount of damage done by an earthquake?

When we discussed earthquake intensity we discussed some of the basic factors that affect the amplitude and duration of shaking produced by an earthquake (earthquake size, distance from fault, site and regional geology, etc.) and as you are aware, the shaking caused by seismic waves can cause damage buildings or cause

Also, what is the intensity of an earthquake is determined by?

Magnitude and Intensity measure different characteristics of earthquakes. Magnitude measures the energy released at the source of the earthquake. Magnitude is determined from measurements on seismographs. Intensity measures the strength of shaking produced by the earthquake at a certain location.

What are the four factors that can affect how much damage an earthquake causes?

There are seven main factors that determine the impact of an earthquake:

  • Distance (along the surface and depth)
  • Severity (measured by the Richter scale)
  • Population density.
  • Development (building quality, financial resources, healthcare, infrastructure, etc.)
  • Communication links.
  • What are the 5 causes of damage during or after an earthquake?

    The ground shaking may also cause landslides, mudslides, and avalanches on steeper hills or mountains, all of which can damage buildings and hurt people. The second main earthquake hazard is ground displacement (ground movement) along a fault. The tsunami was triggered by the Good Friday earthquake.

    What are three effects of earthquakes?

    Earthquake environmental effects are the effects caused by an earthquake on the natural environment, including surface faulting, [[tectonic tsunamis, soil liquefactions, ground resonance, landslides and ground failure, either directly linked to the earthquake source or provoked by the ground shaking.

    Which countries in the world have the most earthquakes?

    Indonesia is in a very active seismic zone, also, but by virtue of its larger size than Japan, it has more total earthquakes. Which country has the most earthquakes per unit area? This would probably be Tonga, Fiji, or Indonesia since they are all in extremely active seismic areas along subduction zones.

    What are some of the hazards associated with earthquakes?

    A large earthquake will always be followed by a sequence of aftershocks.

  • Ground Shaking.
  • Tsunami.
  • Landslides and Rockfalls.
  • Subsidence and Lateral Spreading.
  • Liquefaction.
  • What are the destructive effects of an earthquake?

    Destructive Effects:

  • Earthquake causes dismantling of buildings, bridge and other structures at or near epicenter.
  • Rails are folded, underground wires broken.
  • Earthquakes originate sea waves called Tsunamis.
  • Earthquakes result in the formation of cracks and fissures on the ground formation.
  • What happened to the people after the earthquake?

    It’s basically a smaller earthquake that happens after the main quake, in the same area. If it’s stronger than the first quake, it’s renamed as the main earthquake and the original main quake becomes known as a foreshock. Aftershocks can happen for up to two years after the original earthquake, losing power over time.

    Can you detect earthquakes?

    Can you predict earthquakes? No. Neither the USGS nor any other scientists have ever predicted a major earthquake. We do not know how, and we do not expect to know how any time in the foreseeable future.

    What are the factors of an earthquake?

    There are seven main factors that determine the impact of an earthquake:

  • Distance (along the surface and depth)
  • Severity (measured by the Richter scale)
  • Population density.
  • Development (building quality, financial resources, healthcare, infrastructure, etc.)
  • Communication links.
  • Which type of seismic wave is the most destructive?

    Although surface waves travel more slowly than S-waves, they can be much larger in amplitude and can be the most destructive type of seismic wave. There are two basic kinds of surface waves: Rayleigh waves, also called ground roll, travel as ripples similar to those on the surface of water.

    How does an undersea earthquake cause a tsunami?

    By far, the most destructive tsunamis are generated from large, shallow earthquakes with an epicenter or fault line near or on the ocean floor. These usually occur in regions of the earth characterized by tectonic subduction along tectonic plate boundaries.

    What is the main cause of an earthquake?

    Earthquakes are caused by tectonic movements in the Earth’s crust. The main cause is that when tectonic plates collide, one rides over the other, causing orogeny (mountain building), earthquakes and volcanoes. The boundaries between moving plates form the largest fault surfaces on Earth.

    What should you do if an earthquake strikes your area?

    If you’re indoors, stand against a wall near the center of the building, stand in a doorway, or crawl under heavy furniture (a desk or table). Stay away from windows and outside doors. If you’re outdoors, stay in the open away from power lines or anything that might fall.

    How does it feel to be in an earthquake?

    A large earthquake far away will feel like a gentle bump followed several seconds later by stronger rolling shaking that may feel like sharp shaking for a little while. A small earthquake nearby will feel like a small sharp jolt followed by a few stronger sharp shakes that pass quickly.

    What kind of fault line is the Wasatch Fault?

    The San Andreas fault slips horizontally with little vertical movement. This is called a strike-slip fault. The Wasatch fault slips in a primarily vertical direction, with the mountains rising relative to the valley floor. The Wasatch fault is a so-called normal fault.

    Why would surface waves can be more damaging to buildings than P waves or waves?

    Because the amplitude of surface waves diminishes less rapidly with distance than the amplitude of P or S waves, surface waves are often the most important component of ground shaking far from the earthquake source, thus can be the most destructive.

    What are the effects of earthquakes on the Earth’s surface?

    Effects. Earthquakes often cause dramatic changes at Earth’s surface. In addition to the ground movements, other surface effects include changes in the flow of groundwater, landslides, and mudflows. Earthquakes can do significant damage to buildings, bridges, pipelines, railways, embankments, dams, and other structures

    What are the causes of earthquake?

    Earthquakes are usually caused when rock underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves that make the ground shake. When two blocks of rock or two plates are rubbing against each other, they stick a little. When the rocks break, the earthquake occurs.

    What do you do when there is an earthquake?

    Ensure you do the following if you are outdoors during an earthquake:

  • Stay there.
  • Move away from buildings, streetlights, and utility wires.
  • Once in the open, stay there until the shaking stops. The greatest danger exists directly outside buildings, at exits and alongside exterior walls.
  • Where do most of the world’s earthquakes occur?

    Earthquakes occur all the time all over the world, both along plate edges and along faults. Most earthquakes occur along the edge of the oceanic and continental plates. The earth’s crust (the outer layer of the planet) is made up of several pieces, called plates.

    How can tsunamis occur?

    Tsunami are actually waves caused by sudden movement of the ocean due to earthquakes, landslides on the sea floor, land slumping into the ocean, major volcanic eruptions or large meteorite impacts.
