The 2017 ML 5.4 Pohang, South Korea earthquake, which caused severe damage, raised
attention to the importance of the characterization of the Pohang Basin structure and the …

In a seismic hazard assessment, local geologic and ground conditions play important roles
in characterizing and estimating hazards. We developed a systematically standardized GIS …

The mean shear wave velocity to the depth of 30 m (Vs30) derived from the western Vs is the
current site classification criterion for determining the design seismic ground motion taking …

A mapping of shear-wave velocity for all of Japan is performed using “Japan Engineering
Geomorphologic Classification Map (JEGM)” which has been developed as a GIS-based …

抄録 本研究では, 既存の地盤データベースの問題点を整理し, 日本全国の地形地盤を統一的に

Summary The Dinar earthquake (MS= 6.1) of 1995 October 1 killed 90 people and
destroyed more than 4000 buildings. Despite the moderate size of the earthquake, the level …

The average shear wave velocity for a soil depth of 30 m (VS 30) is crucial for seismic
hazard assessments. However, VS 30 measurements are not available at most recording …

The contemporary two-parameter-based site classification system of Korea, which is depth
to bedrock and averaged shear wave velocity of soil deposits overlying the bedrock, has …

Strong motion attenuation relationship represents a comprehensive trend of ground
shakings at sites with distances from the source, geology, local soil conditions, and others. It …
