Key Points

The study aims to estimate crustal deformation in Minami-Aso Village during two periods surrounding the 2016 Kumamoto Earthquake.
Used airborne LiDAR data from before and after the 2016 Kumamoto Earthquake.
Calculated 3D displacement using the ICP method for spatial correlation of original and ground point cloud data.
Estimated deformation based on terrain differencing method.
Compared estimated displacement from ground data with survey points, yielding similar values.
Local ground deformation such as landslides and ground cracks impacted results depending on window size.

Implication

Analyzes crustal deformation in Minami-Aso, revealing accuracy in displacement estimations.
