Liquefaction is when shaking or stess causes something like soil, sand or silt to act like liquid. The 2011 earthquakes in Christchurch, New Zealand were devastating in many ways, liquefaction being one of them.
Which can be cool.
But mostly a huge pain in the ass.
Liquefaction creates sinkholes under roads which devour anything driving near them.
Not really liquefaction, but worth a look anyway. A boulder rolled *through* this house. Right in one side and out the other side of a kids room. Luckily he wasn't there at the time. He-man is still missing, presumed flat.
Liquefaction is also very effective at destroying sewers, things like these were used for weeks, if not months. Thanks for taking a look at this small collection, Christchurch will rise again, stay safe. =)
