National Research Institute for Earth Science and Disaster Prevention (NIED) deploys the high sensitivity seismograph(Hi-net) and the digital strong-motion seismograph(KiK-net) across the all of Japan, as part of the activities of the Headquarters for Earthquake Research Promotion. This WWW site is established to provide the acceleration data collected by the strong-motion seismograph network. Please use Netscape 4.X, or use Microsoft Internet Explorer 5.X or later. If your platform is the Macintosh, Netscape6.X is recomended.

Main Menu
Use this link if you know the origin time of an earthquake and want to download its data. You can also view and download a hypocentral map here. Please begin with this page.

Use this link to search for earthquakes using the origin time, magnitude, epicenter location, etc.

Use this link to search for acceleration data independent of earthquakes, based on date and time, site location, site characteristics, maximum acceleration, epicentral distance, etc. The data can be compressed into a single tar file.
