Presentation Transcript

  1. Strong Motion Networks, K-NET and KiK-net in Japan WataruSuzuki , Takashi Kunugi, Shin Aoi (National Research Institute for Earth Science and Disaster Prevention, Japan) COSMOS Strong Motion Forum at the 15WCEE, 25 September, 2012

  2. K-NET and KiK-net observation stations K-NET (surface stations, mostly located in peopled areas) KiK-net (pairs of surface and borehole seismographs) Borehole unit Observation facility Surface seismograph

  3. Unified Website of K-NET and KiK-net • Respective Websites of K-NET and KiK-net closed, and a unified site opened on April 6, 2012. • Unified Website provides • Strong motion data (waveform and PGA list) of the earthquake during which the JMA seismic intensity of 2 or larger is registered • Soil condition data down to 20 m depth for K-NET stations, and those to the depth of the borehole seismograph for KiK-net stations • Realtime ground-motion monitor(Kyoshin monitor)

  4. Data Download • Select earthquake from monthly catalogue • Search for earthquake by hypocenter location, magnitude, etc… • Search for strong motion data by PGA, site location, epicentral distance, etc… • FTP site • Direct HTTP link (for COSMOS virtual data center)

  5. Data Download • Select earthquake from monthly catalogue • Search for earthquake by hypocenter location, magnitude, etc… • Search for strong motion data by PGA, site location, epicentral distance, etc… • FTP site • Direct HTTP link (for COSMOS virtual data center)

  6. Data Download • Select earthquake from monthly catalogue • Search for earthquake by hypocenter location, magnitude, etc… • Search for strong motion data by PGA, site location, epicentral distance, etc… • FTP site • Direct HTTP link (for COSMOS virtual data center)

  7. Data Download • Select earthquake from monthly catalogue • Search for earthquake by hypocenter location, magnitude, etc… • Search for strong motion data by PGA, site location, epicentral distance, etc… • FTP site • Direct HTTP link (for COSMOS virtual data center)
