Liquefaction causes soil to lose it's ability to support loads (technically described as a loss of bearing capacity) which can cause subsidence of building foundations.
It can also cause differential subsidence where one part of the ground subsided more than another. When this occurs (especially under buildings) it can cause even more structural damage than uniformly distributed subsidence and also lead to the fracture of underground services such as water and gas mains.
This in turn can lead to a greatly increased risk of fire and explosion and also can hamper the efforts to fight fire due to the damage to water mains.

What risk does liquefaction pose during an earthquakes?
Liquefaction can cause subsidence of buildings and other structures which can lead to structural damage or even collapse. It can also cause differential subsidence where one part of the ground subsided more than another. When this occurs (especially under buildings) it can cause even more structural damage than uniformly distributed subsidence and also lead to the fracture of underground services such as water and gas mains. This can lead to a greatly increased risk of fire and explosion and also can hamper the efforts to fight fire due to the damage to water mains.
How does an earthquake cause each of these types of damage?
Earthquakes cause direct damage when the seismic disturbance weakens and collapses buildings and other infrastructures not built to withstand the tremors. This often causes great loss of life. Other damage caused by earthquakes results from landslides, mudslides, avalanches, fires, soil liquefaction and tsunamis.
Why did liquefaction cause so much damage in some areas of the Christchurch earthquake?
cause it just did.....
What are problems caused by earthquakes?
The effects of earthquakes include 1) Shaking and ground rupture - severe damage to buildings 2) landslides and avalanches 3) fires through the damage of power or gas lines 4) Soil liquefaction - causes buildings to lean and become unstable 5) Tsunami - in the same area or other areas 6) Floods 7) Tidal forces 8) Human impacts such as the spread of disease, death, lack of basic necessities such as water, property and road damage...
What can be done when a new home is being built to prevent damage caused by liquefaction?
to reduce earthquake damage, new buildings must be made stronger and more flexible. older buildings however must be modified to withstand stronger earthquakes

Liquefaction occurs when?
Loose, saturated soil turns into liquid that can't support buildings
What are four ways the earthquakes cause damage?
It is Tsunamis, Aftershocks, Liquefaction, and Shaking.

How can homes and structures can be protected from liquefaction?
To combat damage caused by liquefaction, new homes built on soft ground should be anchored to solid rock below the soil.
What are some effects of earthquakes?
liquifaction, fires, lahars(mudslides) mass destruction of buildings.
How does rain before an earthquake affect the danger of liquefaction?
Liquefaction turns soft soil into mud and then the building sinks. If it were raining, then it would make soil and mud more muddy and more buildings would collapse.
