Aim and points of this workshop: The 2. Workshop on Seismic Observation in Deep Borehole (SODB) and its Applications

The achievements of the first WS and the aim of the Second WS were explained. The purposes of this Second WS were: to re-recognize the significance of seismic ground motion evaluation based on newly added deep borehole seismic observation in addition to existing borehole investigation, geological surveys, and geophysical exploration; to acknowledge deep borehole seismic observation and geophysical exploration (hardware) as well as the site characteristic evaluation method (software) required for seismic ground motion evaluation; and to consolidate opinions on multi-purpose application of observation technology and data as well as acknowledge issues to be addressed and technological problems. The final goals of this WS were to clarify items and issues that present challenges for the future based on the discussions in this WS. (author)
