In Japan, about 1200 high-sensitivity seismic observation stations and about 120 broadband seismic observation stations are installed , and by using these stations the quick detection and determination of the location and magnitude of the small and large earthquakes which occured in and around Japan . These broadband and high sensitivity seismic observation have been carried out by 9 National Universities, JMA , NIED , JAMSTEC, AIST etc. JDXnet (Japan Data eXchange network) is the nationwide real-time distribution network of the data of these seismic stations.
Currently, JDXnet is constructed by using wide-area L2 network of SINET4 and JGN-X as a backbone network, and connect many agency and university and exchange real-time data that each agency has collected from each observation stations. In the Great East Japan Earthquake, drawback of observation network configuration of the University which collect data in each university prior to data exchange on JDXnet was revealed. Therefore, we have installed the relay unit at the east and west data center in SINET4. The relay unit will collect the data from stations and distribute data on JDX-net without going through the university. |
