| Earthquake Information Center (EIC) |
Earthquake Information Center (EIC) has a central role of Japan University Network for the Earthquake Prediction Program, making archives of all seismic data observed in Japan. EIC also creates a database and develops software to analyze the database. To utilize this database, EIC coordinates various collaborative projects among domestic and international researchers, concerning the source process of earthquakes and tsunamis, real-time seismology, strong motion and ground property, earthquake disaster prevention of the metropolitan area, and the communication system for earthquake information.
・Publication of Japan University Network Earthquake Catalog (JUNEC) via CD-ROM
・Construction of the new J-array database system and publication of J-array CD-ROM
・Development and operation of national seismic waveform database utilization system.
・Operation of national joint use parallel computer system
・Publication of the EIC news letter.
・The promotion of the real-time seismology research.
・The promotion of the advantage utilization of the old seismogram.
・Construction and operation of metropolitan area strong motion network SK-net
Distribution of earthquakes determined by JUNEC (1985-1998) and
CD-ROM. The integrated processing of earthquake data got by observation
network of the earthquake prediction observation and information
network managed by Japanese national university is done, and as
"Japan University Network Earthquake catalogue (JUNEC)",
it has been opened at CD-ROM to public.
New J-array web page and CD-ROM.
We developed and installed the web systems such as the New J-array
seismic waveform database. The data has been opened to public
in CD-ROM also.
Parallel computer SGI Altix 3700 system and the situation of utilization.
Parallel computer system for the national joint research of earthquake
and volcano is operated. In order to respond to increasing calculation
demand, it is renewed in three SGI Altix 3700 systems which consists
of 64, 32 or 12 CPUs from March, 2003.
Web page of SK-net: Seismic Kanto Strong Motion Network. We constructed
the system "Seismic anto Strong Motion Network (SK-net)"
which collects the strong motion waveform data of the strong motion
seismometers and seismic intensity meters that were installed
by local governments after the 1995 Kobe Earthquake in metropolitan
area. The data has been opened to public in the web page.
