Research Overview
Soil Liquefaction
Insight on soil information
Support seismic hazard analysis
Prevent significant damage to
infrastructures
Research Goal
Understand the effects of spatially
correlated soil properties on the evaluation
of regional seismic hazards
Visualization Objective
Develop 2D and 3D visualization models of
soil properties
