Observation of Earthquakes for Crust and Upper Mantle Structures in the Kinki District, Japan Kazuhiro NISHIMURA, Kenichi TATSUMI, Setsuro NAKAO, Tsutomu MIURA, Norio HIRANO, Tomoya YAMAZAKI, Masayo FUKUSHIMA, Masato KAMO, Maiko MORI, Kazuhide TOMISAKA, Itaru YONEDA, Kumiko KAWAI, Yoshinori YOSHIDA, Yoshinobu HOSO, Hideki MATSUURA, Takuo SHIBUTANI, Kiyoshi ITO, Hiroshi KATAO, Shiro OHMI, Issei HIROSE, Aiko NAKAO and Kanako MORISHITA* * International Center for Elementary Particle Physics Synopsis Underground structures in the Kinki district were surveyed from 2002 to 2006 under the Special Project for Earthquake Disaster Mitigation in Urban Areas. We carried out seismic observations with deploying 35 temporary stations across the Kinki district from the Pacific side to the Japan Sea side, in order to reveal subsurface structures, such as subducting Philippine Sea slab in southern Kinki and the continental Moho in northern Kinki. About 50,000 event data were selected from continuously observed seismic records of both the temporary stations and nearby permanent stations during May, 2005 and Nov, We also try to develop a data communication system with a mobile telephone for a BREW application to improve the observation system.
