[Termes IGN] station GPSRésumé : (Auteur) Large-scale crustal deformation over a wide area of eastern Japan was detected by GEONET, Japan's dense Global Positioning System (GPS) network, following the 2011 off the Pacific coast of Tohoku Earthquake occurred on March 11, 2011. Since it was assumed that coordinates of the control points for public surveys, such as GEONET stations, triangulation stations and leveling bench marks, in a wide area were greatly changed and could hardly maintain consistency between nearby stations, the Geospatial Information Authority of Japan (GSI) stopped providing ‘Survey Results’ of them, which were the coordinates for survey use, and announced it publicly on March 14, 2011. In order to promote various public restoration programs in the affected area, it was strongly required to revise the Survey Results in an urgent manner. On the other hand, because large postseismic deformation had continued widely after the event, it was concerned that even if the Survey Results were updated immediately, they would become ineffective in a short time. Therefore GSI examined the optimal timing to calculate their new coordinates by predicting the amount of future postseismic movement based on the observation data of GEONET stations. Eventually, the new Survey Results of GEONET stations were published on May 31, 2011 and those of triangulation stations and leveling bench marks on October 31, 2011 respectively. In this paper, we report the revision process of the Survey Results after the 2011 Tohoku Earthquake.

[Termes IGN] Tohoku (Japon)Résumé : (Auteur) This paper presents an overview of crustal deformation caused by the 2011 off the Pacific coast of Tohoku Earthquake, detected by GEONET (GPS Earth Observation Network), the GPS continuous observation system operated by the GSI, and by interferometric SAR (InSAR) analysis using ALOS/PALSAR data. We found that a very wide area of the Japanese Islands, from Hokakido to the Kinki district, was remarkably affected by the crustal deformation caused by the mainshock of the Tohoku Earthquake. We estimated the geometry of the seismogenic fault of the earthquake, as well as the slip model for the plate boundary between the Pacific plate and the North American plate, from the crustal deformation data obtained from GEONET. The fault is estimated to be longer than 400 km, stretching from off Iwate Prefecture in the north to off Ibaraki Prefecture in the south. The largest slip estimate for the plate boundary is more than 56 m in the off-Miyagi region near the Japan Trench. Postseismic crustal deformation is also observed by GEONET, indicating that slow postseismic slip is ongoing along the plate boundary around the main fault zone. Additionally, we detected clear coseismic signals associated with induced inland earthquakes in the Fukushima-Hamadori area from InSAR analysis. The InSAR results show obvious displacement discontinuities, suggesting that rather shallow ruptures occurred. In particular, for the Mj 7.0 event on April 11, the observed displacement boundaries correspond to earthquake surface ruptures that appeared just along the Idosawa and Yunotake faults.

[Termes IGN] visualisation 3DRésumé : (Auteur) On 11th May 2011, two earthquakes with their epicentres in Lorca caused significant damaged in the region of Murcia, Spain. A new flight was carried out in the region three days after the earthquake to obtain more accurate Lidar data to supplement the data that was already available thanks to the PNOA project from 2009. The new Lidar data was also made available to anyone who needed it, allowing the damage to be assessed quickly and efficiently. In the case of a natural disaster, releasing data obtained both from flights beforehand and afterwards allows relevant users to create an inventory of the damage and detect any changes quickly and accurately using the appropriate tools.

[Termes IGN] séismeRésumé : (Auteur) Remote sensing technology is a powerful tool to extract regions damaged after an earthquake. There are two methodological approaches in detection of earthquake damage: mono-temporal and multi-temporal. Especially for providing effective emergency management, the mono-temporal approach is generally preferred in extraction of earthquake damage as it does not depend on availability of pre-earthquake imagery. For this purpose, a novel method called support vector selection and adaptation (svsa) has been introduced to detect the damaged regions from a post-earthquake image. In this study, the SVSA method was applied to the region where the Haiti Presidential Palace and Cathedral is located, and the damaged regions were identified. The performance of the SVSA method in identification of the damaged regions was evaluated by comparing the thematic maps obtained by classifying pre- and post-earthquake images. Additionally, the damage patterns for the city of Port-au-Prince were estimated by the SVSA.
