Prof.TAKANO Kiyoshi, Earthquake Research Institute, Center for Integrated Disaster Information Research, Interfaculty Initiative in Information Studies, the University of Tokyo, Prof. FURUMURA Takashi, Center for Integrated Disaster Information Research, Earthquake Research Institute, the University of Tokyo, and D.Sc. ITO Takamori, Project Researcher, Earthquake Information Center, Earthquake Research Institute, the University of Tokyo, who are Japanese Researchers for strong motion sensor and building sensor (Group 1 sub-groups) of DISANET, visited to India from 9 to 14 November in order to exchange views on current research in India and Japan regarding building motion sensor and strong motion sensor.
Some equipment provided at this occasion
Presentation by Prof. Takao
DISANET, starting from July 2010 as a 5 year joint research and development project between India and Japan, aims at establishing infrastructure for continuous data collection on earthquake and weather with global information network by applying it to India and Japan as example cases and to develop technical bases for rescue and support for restoration and for disaster recovery support. To measure building motion and assess the vulnerability based on such data is useful to develop policies and regulations to mitigate disasters caused by earthquake, so that is an important activity of DISANET.
Japanese research team provided building motion sensors to International Institute of Information Technology, Hyderabad (IIITH), who is an Indian counterpart for building sensor research (Group 1 sub-group of DISANET). During the visit, Japanese researchers gave a demonstration of that equipment. Prof. Takano also provided a presentation to Indian researchers about the current 3D visualized research on building motion sensors in Japan.
Presentation by Prof. Furumura
To predict the impact of earthquake from a seismic center to distant areas is also an important activity of DISANET. Prof. Furumura, who develops a mathematical model to predict impacts of a strong motion, provided a presentation on the simulation of strong motion by using experiences of Japan, which has frequent earthquakes. His presentation was very clear to make a point that there is a high possibility that an impact of earthquake reaches to distant areas regardless of such a long distance from the seismic center.
Japanese researchers listening to presentations by Indian researchers
Responding to such presentations by Japanese researchers, Indian researchers also made presentations on the current researches in India. The area of researches are so various that presentations included simulations of a building motion, modeling a strong motion, a small scale earthquake vulnerability mapping, introducing an observatory of motion sensor near the dam site, and so on. All the Indian researchers of strong motion and building sensor researches (Group 1 sub-groups of DISANET), currently working in IIITH and National Geophysical Research Institute (NGRI), had been studying in Japan before DISANET started. Thus, both Indian and Japanese researchers renewed old friendship at this occasion as well.

Japanese researchers with Indian researchers in front of NGRI
IIT-H did not have any faculties related to such research areas at the time when DISANET started, though IIT-H is the implementing research institute of DISANET in India. However, as the number of full-time faculties in IIT-H increases, there became researchers in IIT-H who can share a similar research interest. At this occasion of the visit by Japanese research team, some faculties from IIT-H actively joined to discussions and proposed their interests in related research in the area of building motion.
As such, the visit by Japanese researchers, despite a short duration, was a fruitful one to exchange current research findings in India and Japan.
