Abstract: Liquefaction is a common cause of ground failure during earthquakes and is directly responsible for tremendous damage to infrastructure. Evidence of the impact of liquefaction includes failure of bridge foundations due to lateral spreading, settlement and tilting of structures, cracking and buckling of roadways, and failure of buried lifelines (e.g. water, sewer, gas, and electrical lines) due to flotation or differential movements, among others. These effects were vividly displayed during the 2010-2011 Canterbury earthquake sequence (CES) in New Zealand, which caused widespread, severe, and recurrent liquefaction throughout the city of Christchurch.
