Center for Engineering Strong Motion Data (strongmotioncenter.org)
The Center for Engineering Strong Motion Data (CESMD) is a cooperative center established by the US Geological Survey (USGS) and the California Geological Survey (CGS) to integrate earthquake strong-motion data from the CGS California Strong Motion Instrumentation Program, the USGS National Strong Motion Project, and the Advanced National Seismic System (ANSS). The CESMD provides raw and processed strong-motion data for earthquake engineering applications.
Engineering Strong-Motion Database (esm-db.eu)
ESM, the Engineering Strong-Motion Database, provides a set of facilities to search, select, download and analyse ground-motion data and associated metadata. The waveforms contained in ESM are relative to events with magnitude ≥ 4.0, mainly recorded in the European-Mediterranean regions and the Middle-East. ESM is targeted to applied seismologists, earthquake engineers, professional engineers, geologists and policy makers.
K-NET and KiK-net (bosai.go.jp)
K-NET (Kyoshin Network) is a nation-wide strong-motion seismograph network, which consists of more than 1,000 observation stations distributed every 20 km uniformly covering Japan. K-NET has been operated by the National Research Institute for Earth Science and Disaster Resilience (NIED) since June, 1996. At each K-NET station, a seismograph is installed on the ground surface with standardized observation facilities.
KiK-net (Kiban Kyoshin Network) is a strong-motion seismograph network, which consists of pairs of seismographs installed in a borehole together with high sensitivity seismographs (Hi-net) as well as on the ground surface, deployed at approximately 700 locations nationwide. NIED constructed KiK-net under the plan ‘Fundamental Survey and Observation for Earthquake Research’ directed by ‘the Headquarters for Earthquake Research Promotion’.
The strong-motion data recorded by K-NET and KiK-net are immediately transmitted to the data management center of NIED in Tsukuba. The observed strong-motion data are widely available to the public through the internet from this web site. The soil condition data explored at K-NET stations and the geological and geophysical data derived from drilling boreholes at KiK-net stations are also available.
User registration is required to download K-NET and KiK-net data.
