A new system (DataStation, DataCraft) which we have developed, compared with an old version, has various merits such as increase of types of equipment of the seismograph to be applied, provision of early earthquake detection process function and making possible to process a large quantity of data collectively. The early earthquake alarm seismograph will be installed increasingly along the meter gauge lines in near future. When existing seismograph are to be replaced with this early earthquake alarm seismograph, we should confirm the appropriateness of installing the new system based on the analysis of the past data.
