J-Shis - An Integrated System for Sharing Information on National Seismic Hazard Maps for Japan


Abstract eng:
The National Seismic Hazard Maps for Japan (NSHMJ) are issued by a governmental organization, the headquarters for earthquake research promotion of Japan, to estimate strong motions caused by earthquakes that could occur in the future and show the estimated results on the maps. The NSHMJ consists of two types of maps that are different in nature: the probabilistic seismic hazard maps and the scenario earthquake-shaking maps for specified seismic source faults. The probabilistic seismic hazard maps are based on the PSHA that combines long-term evaluations of earthquake occurrence and strong motion evaluation. An integrated system of Japan seismic hazard information station (J-SHIS) has been developed since 2005 for sharing NSHMJ information. The system manages various data in an integrated manner, including provide detail NSHMJ information and site amplification models with a 250m mesh resolution, and the deep subsurface velocity structure models. The system is also capable of providing these data in a user-friendly manner by showing them over background maps. This J-SHIS system is a web mapping system based on open source software that allows public users to easily view various data by Internet browsers. Based on the lessons learned from the 2011 Great East Japan Earthquake disaster, the revised NSHMJ have been published. In order to meet increase of need to promote the understanding of seismic hazard assessment, we added a new function to the J-SHIS for viewing NSHMJ either in PC or a portal smartphone. Moreover, we provide a service of ‘Seismic Hazard Karte’, an integrated information system on seismic hazard for every 250m mesh. In order to promote the utilization of J-SHIS data in interoperable system, development of J-SHIS Web application programming interface (API) has been progressed. Based on the API, several applications in smart phones that use JSHIS data are newly published. Moreover we have been developing the J-SHIS functions as a basis for transmitting seismic hazard information for needs of earthquake disaster reduction in municipals and governments.
