The Japan Seismic Hazard Information Station, J-SHIS for short, is an open web system that shows national seismic hazard maps of all over Japan including parameters of seismic fault model, site amplification, and deep subsurface etc.

The national seismic hazard maps for Japan are a comprehensive integration from all of the research aspects conducted by the Headquarters for Earthquake Research Promotion (HERP) after the lessons learned from the 1995 Hyogo-ken Nanbu earthquake. It contains information of all necessary data for producing the maps. To cross-check and promote the use of the national seismic hazard maps, an engineering application committee was established by NIED. Under the committee guidance, we developed an open web system to provide information interactively in 2005, and named this system as Japan Seismic Hazard Information Station, J-SHIS. Our products are aimed to meet multi-purpose needs in engineering fields by providing information of the probabilistic seismic hazard analysis. The information provided from J-SHIS includes not only results of the hazard maps, but also various information to produce the hazard maps, such as data on seismic activities, seismic source models and underground structures.
The new J-SHIS provides with resolution about 250m for Probabilistic Seismic Hazard Map (PSHM) and Scenario Earthquake Shaking Map (SESM) based on detailed strong motion prediction for earthquakes occurring at the major active faults. The new J-SHIS offers functions to superpose J-SHIS maps on background maps, and search functions by address, postal code and so on. Now, it becomes easy to show seismic hazard information at any points of all Japan. For utilizing J-SHIS data professionally and technically, it is available to download J-SHIS data including the National Seismic Hazard Maps, parameters of seismic fault model, site amplification, deep subsurface model, and so on.
We hope the updated J-SHIS will be utilized as the fundamental materials for awareness-raising of earthquake disaster prevention, and for effectiveness of earthquake countermeasures.
