Collapse of wooden house (Map ①)
The Japanese building code was upgraded in 1981. About 65% of the residential house was build
before 1981 in Suzu City. This number is largest in Japan. These old houses were collapsed so much.

Concluding remarks• The massive earthquake that struck a depopulated and aging area is revealing avariety of issues.
• 100% of water supply is still cut off in Suzu City and Wajima City, and many
residents are still living as displaced.
• The Japanese building code was upgraded in 1981. About 65% of the residential
house was build before 1981 in Suzu City. This number is largest in Japan.
These old houses were collapsed so much.
• The ground motion itself was very large, but it became clear that the effects ofground deformation induced by liquefaction and landslide were also large in theaffected area.

• A tsunami occurred immediately after the earthquake, and Suzu City is estimatedto have been hit by a tsunami of 2.9 to 4.3 meters.

The reconnaissance work was conducted as an activity of theresidential land group of JGS (Japanese Geotechnical Society).
We express sincere appreciation to the group members.
We would like to express our deepest sympathies to thoseaffected by the disaster and pray for the repose of the souls of
those who lost their lives. We pray for the earliest possible
recovery of the affected areas.
