We are investigating rupture events of active faults and plate-boundaries that have occurred over the past few thousand years and estimating the intervals and magnitudes of earthquakes and tsunami disasters based on topographic and geologic surveys. We are also conducting research on the simulation-based prediction of earthquakes using geophysical models and the detection of precursors of the Tokai, Tonankai, and Nankai earthquakes based on observations of groundwater and crustal movements.Tsunami flooded areas of the 2011 Tohoku (blue area) and the 869 Jogan (red dash line) earthquakes in the Sendai Plain 【 Outline 】【 Director 】 Yoshio Watanabe 【 Deputy Director 】Satoshi Tsuchida Geoinformation CenterIntegrating and providing reliable and impartial geoinformation for the public URL : http://www.gsj.jp/geoinfo-center/center-en.htmlAIST Tsukuba Central 7, 1-1-1 Higashi, Tsukuba, Ibaraki 305-8567, JapanTel : (029) 861-3601 / Fax : (029) 861-3602(from outside Japan : Tel: +81-29-861-3601 / Fax: +81-29-861-3602)We provide reliable and impartial geoinfomation for the public in close coordination with the geoscience research divisions. We develop geoscientific data infrastructure and promote the geological standardization in order to meet greater needs in Japan. We register the metadata of geological publications and build bibliographic database. Integrated database of geoinfomation and satellite images is another major task of us for interoperable data dissemination through the web.【 Location 】 AIST Tsukuba (Central)【 Outline 】05 kmSendai airportNatori RiverInferred shoreline at 869 JoganTsunami inundation area of the 2011 Tohoku earthquake observed by GSJSimulated tsunami inundation limit of the 869 Jogan earthquake(model 10; Namegawa et al., 2010)Distribution limit of sandy deposit transported by the 2011 tsunamiDistribution limit of muddydeposit transported by the 2011 tsunamiTsunami deposit of the 869 Jogan (probable)Tsunami deposit of the 869 Jogan (possible)Sendai cityInternational standard delivery of geological information by integrated portal39Organization and OutlineGeological Survey and Applied Geoscience
