COSMOS Strong Motion Forum at the 15WCEE, 25 September, 2012

1. 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

2. 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)
