Earthquakes

This is the vibration that we feel when energy built up by the application of stress to the lithosphere is released by faulting during an earthquake

• Fault Slipping

• Fault Shake

• Ground Shaking

• P and S Waves

This occurs when static shear stress in the soil is greater than the shear strength of the liquefied soil.

• Flow Liquefaction

• Cyclic Liquefaction

• Soil Liquefaction

• Earthquake

An active fault is defined as a fault which has moved within the last______?

• 15,000 years

• 10,000 years

• 13,000 years

• 20,000 years

All of these are types of liquefaction features except:

• Settlement

• Deforestation

• Flow Failure

• Lateral Spreads

______ is the phenomenon in which the static equilibrium is destroyed by static or dynamic loads in a soil deposit with low residual strength.

• Ground Oscillations

• Settlement

• Lateral Spreads

• Flow Failure

What earthquake hazard is shown in the picture?

• Ground Rupture

• Liquefaction

• Earthquake-induced landslides

_______ is a series of giant sea waves commonly generated by under-the-sea earthquakes and whose heights could be greater than 5 meters.

• Earthquake

• Tsunami

• Ground Shaking

• Liquefaction
