Liquefaction occurs in cohesionless soils (typically those with a higher content of larger grains such as sand sized clasts) which have water in the pore spaces, and are poorly drained.
When the seismic waves from the earthquake pass through the soil, the vibrations cause the individual grains in the soil to move around and re-adjust their positions. This ultimately results in a decrease in volume of the soil mass as the grains pack more tightly together (a reduction in porosity).
The pore water which was originally in those spaces becomes compressed. Water is relatively incompressible and as such it pushes back against the soil grains (more correctly this is described as an increase in pore water pressure). The pore pressure becomes so high, that the soil grains become almost buoyant causing a significant drop in the shear strength of the soil to a very low value and causing it to behave as a viscous liquid rather than a solid.
When this occurs the soil loses it's ability to support loads (technically described as a loss of bearing capacity) which can cause subsidence of building foundations leading to structural damage.

It depends the area of study where the term is used.
Loose, saturated soil turns into liquid that can't support buildings

Body
Waves that can make the ground roll like ocesn waves; they usually cause the most damage during the earthquake
It is Tsunamis, Aftershocks, Liquefaction, and Shaking.
The valdivia earthquake caused a lot of damage. But I am not sure what kind of damage it caused.
Earthquake aftershocks.the arrival of surface waves
boom panes
cause it just did.....
the arrival of surface waves liquefaction a tsunami an aftershock
It can be cause by liquefaction.
because
The L- Wave or the Love and Rayleigh waves (collectively known as surface waves) cause most of the damage during an earthquake.
