In order to investigate the seismicity of microearthquakes in relation to the occurrence of large shocks, an array of observation stations spread widely over the northern part of the Kinki District, was being operated since 1963.
The array was substituted for a new telemetered system in 1975, to get the simultaneous and real time recordings. A data processing system with a digital computor was, at the same time, equipped and is playing an important role in analysing and filing an abundant supply of data. This total system is, therefore, of practical use for saving labor and refining data.
In this report, the constitution and function of the system are described in some details, together with some examples of more refined analyses.
