| Outline of Final Research Achievements |
Seismographs are crucial for understanding a variety of aspects of earthquake-inflicted property damage and human suffering. However, strong ground motion records are often missing or very sparsely available especially in the developing countries, discouraging all attempts for rational rehabilitations. Soils are hysteresis materials exactly like a magnetic tape recording the past. As long as clear evidence of past large soil deformation was there in images obtained through remote sensing technology, we could bring potential hazard to light and take necessary actions. Ground deformations that appeared in the 2011 Great East Japan earthquake, 2015 Nepal Gorkha Earthquake and 2016 Kumamoto earthquakes were thoroughly investigated, and obtained lessons were transferred to relevant organizations.
