From hata at gsi.go.jp Thu Mar 17 03:54:58 2011 From: hata at gsi.go.jp (Yuki Hatanaka) Date: Thu, 17 Mar 2011 19:54:58 +0900 Subject: [IGSMAIL-6369] Preliminary results on the March 11, 2011 M9.0 Earthquake in Japan on GSI's web page Message-ID: <4D81E882.10207@gsi.go.jp> Dear colleagues, I would like to inform you that preliminary results of the crustal deformation associated with the M9.0 earthquake in Japan on March 11, 2011 and the fault models obtained by the routine solutions of GEONET is uploaded on the English web page of Geospatial Information Authority of Japan (GSI): http://www.gsi.go.jp/ENGLISH/index.html Click the items in the "New topics" for detail. I just remark that the temporal resolution of the three types of the routine solutions are 6 hours for the quick solutions (Solution ID: Q3), and 24 hours for the rapid (R3) and final (F3) solutions. Some amount of post-seismic deformation is, hence, not separated from the "co-seismic" displacement and models. According to the Geodetic Observation Center of GSI, at least 3 GEONET stations were damaged by Tsunami and terminated the observation. As of March 17, we cannot retrieve data from 25 stations around the epicenter due to the failures of power or communication line. IGS stations operated by GSI are safe, but coordinates of TSKB are affected by the crustal deformation from the earthquake.
