Water pipes tend to fracture or crack when an earthquake occurs rather than burst (something bursts when the pressure applied to it's internal surface gets to large and exceeds the strength of the material is is formed from - a bit like if you force to much air into a balloon).
Pipes tend to fracture because the seismic waves make the ground move up and down, backwards and forwards and side to side. This causes the pipe to be bent in differing directions as well as being squashed and stretched. These compression, shear tensile and torsion force will, if they are large enough, create stresses within the pipe wall that are large enough to break it, forming a crack.

How can earthquakes cause pollution?
Earthquakes can cause water pipes, gas pipes, and underground sewers to burst or break, refineries to be damaged, etc. which causes pollution.
What are the short term effects of earthquakes?
Many things, like deaths, buildings collapsing, water pipes bursting, power cuts, burst pipes, no signal, contaminated water, fires, landslides, mudslides, tsunamis, and many more...
How can utilities be made safer to avoid damage during and after earthquakes?
Often much of the damage during earthquakes comes from fires and flooding caused by damaged utilities. Gas pipes or water mains can be broken during the earthquakes. Flexible joints in the lines can protect them from breakage and automatic shut-off valves can be used to stop gas and water flow.
How can water cause mechanical weathering?
Mechanical weathering occurs when physical forces break rock into smaller and smaller pieces without changing the rock's composition. Each piece has the same characteristics as the original rock. When liquid water freezes and expands, it exerts an outward force. This force is great enough to burst water pipes during winter.
Why do you think streets are often flooded after an earthquake?
Broken water pipes would be the main reason. In some cases tsunamis follow earthquakes in costal regions as we have seen in Japan.
Why do water pipes sometimes burst during severe winter?
Water pipes burst during severe winter because water freezes and expands
How can earthquakes cause pollution?

Why do water pipes burst during severe frost?
Because water expands when it freezes.
Water pipes some times burst during severe wintres in cold countries?
water expands on freezing
Because of this anomalous expansion of water that water pipes sometimes burst during winter?
Anomalous expansion of water and bursting of water pipes during winter is because ice takes more space than water
Will PVC pipes burst if water off?
No
Why do water pipes burst in winter?
because the water inside the pipes freezes which causes ice to be created, which then expands and causes the pipe to burst
Why do water pipes burst when water freezes in them?
Becuase when water freezes, it expands and burst the pipe from the inside.
During a cold night water pipes sometimes burst What is the reason for that?
They freeze. Water expands when it freezes and the pipe breaks.
Water pipes burst in winter Why?
Because when water freezes it expands thus bursting the pipes.
Why do water pipes sometimes burst during the winter?
The water inside uninsulated pipes may freeze and expand during a cold winter, pushing opening joints or splitting the pipes, often unnoticed. When the thaw comes, the ice in the pipes melt, and the water pressure returns, and the water is able to spray out through the damaged pipes.
Why water pipes sometimes burst during winter?
In the winter, water pipes can sometimes burst. This is because the water expands as it freezes into ice, and this causes an increase in pressure inside the pipe. When the pressure gets too high for the pipe to contain, it breaks and bursts water.
