Japanese Geotechnical Society ◆  National society of ISSMGE ◆ Member > 8,000 ‘Lessons and Recommendations from the Great East Japan Earthquake’ - Geo-Hazards during Earthquakes and Mitigation Measures - Jul. 2011 Sep. 2011 Jun. 2012 Primary (Japanese) Primary (English) Secondary (Japanese) anied 5
9 Themes   &   56  Recommendations
1. Damages of residential houses, life-lines, road facilities, etc. by liquefaction of ground 2. Damages of residential land in hilly areas and reclaimed lands 3. Damages caused by the huge tsunami 4. Ground subsidence in wide areas and flood control in lowland areas 5. Environmental issues of disaster wastes, tsunami deposits, and contaminated soils by radioactive materials 6. Advanced geotech. engineering for natural slopes, cut earth and various infrastructure facilities (roads, railways, rivers, sewers, ports, airports, power facilities etc.) 7. Restoration and reconstruction of industrial facilities 8. Severe accident measures for important infrastructures 9. Qualification system and education of geotech. engineers and public relations
2.7  Accountability to the owners of new private houses When building a house, the builders of houses (home seller) should explain the owners (home buyers) the safety of residential land and foundation ground, in addition to the safety of the houses. He or she should also explain the owners the effect and cost with a variety of seismic retrofitting measures which can be employed, as well as earthquake insurance as an alternative scheme.
9.1  Establishment of new qualification system of geotech. engineers
It is important that geotechnical engineers with ethics and expertise are appreciated properly in society, and work actively in explaining and check the quality of the ground. For this purpose, a new qualification system ‘Geotechnical engineers for ground quality evaluation’ should be established with the aim to contribute to the mitigation and prevention of geo-disasters.
