The earthquakes occurred in New Zealand in 2011 [15], [16] and in Indonesia in 2018 [17], [18] have demonstrated the extensive nature of liquefaction that the mitigation of liquefaction requires treatment of a wide area or even an entire sand layer. To keep costs reasonable, the selected method for mitigating liquefaction must have a low unit cost.
