This model is a three-dimensional underground structure model from earthquake bedrock (Vs3200) to engineering bedrock (Vs350). This model was created by creating a shallow ground structure shallower than the engineering bedrock, connecting the depth below the engineering bedrock, and verifying the periodic characteristics and amplification characteristics using earthquake records and microtremor observation records, etc. The data is created with the 7.5-arc-second mesh (about 250m grid).
