High intensity of earthquake on Chiba prefecture lead to the potential deformation occurrence. Observe the phenomena of land deformation, SAR data analysis is required. Persistent Scatterer Interferometry (PSI)technique was applied to extract the information using Synthetic Aperture Radar (SAR) data of ALOS-2 PALSAR-2 provided by the Japanese Aerospace Exploration Agency (JAXA). The technique is capable of measuring the changing in earth surface. The time acquisition of SAR data is taken from September 9, 2014, to January 9, 2018, for descending orbit. The result present land deformation in some area on Chiba prefecture. The data obtained from PSI processing is comparing with the data of epicenter of the earthquake in the study area. © 2019 IEEE.
