Palu-s earthquake was happened on September 28, 2018, provided the liquefaction hazard. Liquefaction was evaluated by shear wave velocity (Vs) obtained from the average Vs that occur along 30 meters. Not only Vs, but qu or end resistance also, obtained from the CPT Test. And the last is N-SPT. The highest value that influences the occurrence of liquefaction is the value of qu. This is because the CPT test has only a few error factors which are only in the form of conus, while the others are SPT in the amount of hammer, high distance of the fall, sampling technique. Whereas Vs, the shear wave data processing and calculation processes are on average Vs30 or AVS30.
