K-net is a network of strong-motion seismographs installed at approximately 1000 locations nationwide. K-net is capable of recording strong and destructive seismic motions.
KiK-net is composed of pair of strong-motion seismographs installed at Hi-net observation sites on and under the ground. Seismic data is open to the public.
Various maps of the National Seismic Hazard Maps for Japan and the downloading of numerical data is available.
Database of site amplification factors based on the geomorphological land classifications per 500m mesh of Japan land.
Annual report and news of earthquakes, for seismic intensities over 5 are available.
Materials list at the Matsushiro earthquake center is open to the public.
Hi-net is an observation network composed of high-sensitivity seismographs deployed at approximately 800 locations nationwide. The sensor is installed at the base of the borehole deeper than 100m. Hi-net is capable of detecting seismic motions that are too weak to be felt by people.
F-net is an observation network composed of high-sensitivity seismographs deployed at approximately 70 locations nationwide. f-net is capable of accurately detecting slow ground motions originating from remote seismic sources.
