Describe What Happens in the Earth When an Earthquake Occurs

Earthquakes can happen along any type of plate boundary. An earthquake is the shaking of the surface of Earth due to the sudden release of energy in the Earths crust as a result seismic waves also known as S waves are created.

How Do Earthquakes Happen What Is An Earthquake Youtube

In a mountainous terrain landslides may occur and sometimes small hills disappear or are levelled to the ground.

. The combined events killed more than 500 people. The strength of shaking from an earthquake diminishes with increasing distance from the earthquakes source so the strength of shaking at the surface from an earthquake that occurs at 500 km deep is considerably less than if the same. An earthquake is the shaking and vibration of the Earths crust due to movement of the Earths plates plate tectonics.

Once theres enough molten rock called magma and enough pressure on it a volcanic eruption occurs. The tectonic plates are always slowly moving but they get stuck at their edges due to friction. When the stress on the edge overcomes the friction there is an earthquake that releases energy in waves that travel through the earths crust and cause the shaking that we feel.

When this happens an energy is released in the form of waves also known as seismic waves that travel through the Earths layers and cause the shaking of the ground. As plates move against each other sometimes the rocky edges catch against one another. Earthquakes are caused by sudden movement in opposing tectonic plates in the earth.

An earthquake is caused by a sudden slip on a fault. So powerful was the shaking that by one NASA estimate it shifted Earths. When an earthquake occurs seismic waves are created which propagate away from the focus or hypocenter.

When an earthquake occurs different types of energy waves are generated. These are called aftershocks. These are compressional waves that push and pull as they move through rock and fluids.

On Earth the lava comes up from the mantle which is the layer under the surface. As the P-wave passes each seismic station its arrival time is detected and noted by the real-time computers. What happens to earths Crust after earthquake.

Notable strike-slip quakes include the 1906 San Francisco 2010 Haiti and 2012 Sumatra earthquakes. The rest of the plate remains in motion putting stress on the sticking point and when it gives way an earthquake occurs. Such a process would make the ground sink suddenly in a process called fluidising.

The shaking of the ground that occurs when rock below Earths surface breaks is called an earthquake. When two tectonic plates are passing one another the amount of kinetic. Aftershocks are minor earthquakes that may occur several hours months or even years after the original shock.

The 2012 Sumatran quake was particularly powerful. The seismic activities in an area determine the type and intensity of the earthquake. When these earthquakes occur on land on the other hand they can cause large amounts of damage.

When an earthquake occurs stress and energy along faults increase until the rock breaks and a huge amount of stored energy is released. The fastest waves the P-wave travels outward at a speed of about 3 to 5 milessecond. Stress builds along a fault and when the stress is released in the form of seismic waves at the focus the seismic waves spread out in all directions reaching the epicenter first.

I Describe what happens to the tectonic plates along a transform boundary at the moment when the earthquake occurs. After the earthquake the crust has been repositioned and frictional tension at fault lines once again begins to mount until the next earthquake. Earthquake vibrations can cause sandy soils to liquefy.

P waves or primary waves are the first waves to be detected. The motion of the plates in the plate boundary causes the stress that breaks the crusts along a fault. Earthquakes occur in the crust or upper mantle which ranges from the earths surface to about 800 kilometers deep about 500 miles.

Describe what happens along a fault beneath Earths surface when an earthquake occurs. Its 86 magnitude was the largest ever recorded for a strike-slip fault. There are different types of stress that cause earthquakes depending on how the rocks are moving.

An earthquake depending on its magnitude and location can induce physical phenomena such as ground shaking surface fault rupture ground failure and in some coastal locations tsunamis. A major earthquake is also followed by smaller tremors like an echo. An earthquake also known as a quake tremor or temblor is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earths lithosphere that creates seismic waves.

The shock triggered a tsunami which devastated coastal communities. Earthquakes can range in size from those that are so weak that they cannot be felt to those violent enough to propel objects and people into the air and wreak destruction across. In many volcanoes the magma rises up through a central tube or throat and emerges out the top of the mountain.
