What occurs when an earthquakes violent shaking suddenly turns loose soft soil into liquid mud?

Liquefaction occurs when an earthquake’s violent shaking suddenly turns loose, soft soil into liquid mud.

Which term is defined as turning loose soil into liquid mud by the vibrations of an earthquake?

Soil liquefaction, also called earthquake liquefaction, ground failure or loss of strength that causes otherwise solid soil to behave temporarily as a viscous liquid. Poorly drained fine-grained soils such as sandy, silty, and gravelly soils are the most susceptible to liquefaction.

What happens to wet loose soil during an earthquake?

Liquefaction is the process which causes soil to behave more like a liquid than a solid during an earthquake. The shaking rearranges sand and silt grains in wet soil underground and the water between the grains is squeezed. The rising water takes silt and sand with it, forming sand boils or volcanos. …

What process occurs when an earthquake shaking?

When an earthquake occurs, the elastic energy is released and sends out vibrations that travel in all directions throughout the Earth. These vibrations are called seismic waves. The point within the earth where the fault rupture starts is called the focus or hypocenter.

What do you call a stress that stretches rocks so that it becomes thinner in the middle?

Tension The stress force called tension pulls on the crust, stretching rock so that it becomes thinner in the middle. The effect of tension on rock is somewhat like pulling apart a piece of warm bubble gum. Tension occurs where two plates are moving apart.

What type of stress pulls rock stretching it until it becomes thinner in the middle?

Tension
Tension pulls on the crust, stretching rock so that it becomes thinner in the middle. What type of landform results from tension? Compression squeezes rock until it folds or breaks.

When an earthquake occurs where would Shaking be stronger?

The point at the Earth’s surface directly above the focus is called the epicenter of the earthquake. At the epicenter, the strongest shaking occurs during an earthquake. Sometimes the ground surface breaks along the fault. Sometimes the movement is deep underground and the surface does not break.

What happens to soft soil during an earthquake?

Occurs when an earthquake’s violent shaking suddenly turns loose, soft soil into liquid mud. Acronym to help remember what happens in a normal fault: hanging wall down, normal fault caused by tension. Acronym to help remember what happens in a reverse fault: hanging wall up, reverse fault, compression.

What causes the Earth to shake during an earthquake?

Earthquakes are caused by an abrupt shift of rock along a fracture in the Earth. Most earthquakes are caused by slow movements inside the Earth that push against the Earth’s brittle, relatively thin outer layer, causing the rocks to break suddenly. This outer layer is fragmented into a… My answer:

Where does the most violent shaking of the Earth occur?

Place on the Earth’s surface directly above the focus of an earthquake. The most violent shaking occurs here. Travel along the surface of the Earth. Slowest waves. Produce rolling, up and down and back and forth motion. Cause the most damage. Also called S-waves. Move rock from side to side, at right angles to the waves.

How does geology affect the intensity of an earthquake?

conditions of the local geology influence events: solid bedrock is far less subject to intense shaking than loose sediment; duration and intensity of the earthquake are subject generally to the size of the earthquake; distance: the distance from the epicentre drops off so the intensity of the shaking decreases.
