2. An earthquake is the sudden release of strain energy in the Earth’s crust, resulting in waves of shaking that radiate outwards from the earthquake source. When stresses in the crust exceed the strength of the rock, it breaks along lines of weakness, either a pre-existing or new fault plane. Earthquake motion can turn loosely packed, water-saturated soil to liquid. SCIENCE

3. QUESTION 1. What do you call to a phenomenon in which the strength and stiffness of a soil is reduced by earthquake shaking or other rapid loading?
