Observation system of the seismic wave has greatly progressed and many accelerometers have been set all over Japan. Furthermore, the data processing procedure was developed and the reasonable permanent displacement and the displacement wave were going to be obtained from the measured acceleration data. The baseline correction method was adopted as a data processing procedure. To estimate the adaptability of the baseline correction method, the permanent displacements and displacement wave of major records in 2003 Off Tokachi Earthquake were calculated. The displacements were compared with the data of JAPAN Geographical Survey Institute and Port and Harbor Research Institute. These data were fairly similar to each other. Additionally, sloshing response of the fired large liquid storage tank in Tomakomai was calculated using these data. The baseline correction method presented here can be used successfully to correct strong motion records and present the displacement data for the seismic design and the vibration test.
