Can land fill be liquefied?
Land fill tends to undergo liquefaction in earthquakes. If you take a bucket of water-saturated sand and press down on it with the flat of your palm it will act like a relatively stable solid. But if you shake the bucket hard enough and long enough, the sand becomes loose and pourable -- like a liquid. In an earthquake, what seems like a solid foundation can turn into quicksand in a matter of seconds. This can damage gas and water mains and electrical lines, dramatically sink or tilt buildings, or cause them to collapse.
