抄録

Role of microearthquakes for earthquake prediction is discussed, mainly on the basis ofinvestigations at the Disaster Prevention Research Institute.Microearthquakes are useful for earthquake prediction not only as an indicator for largeearthquakes but also as a tool of trial and error method approaching prediction. Particularly, the spatial-temporal change of the pattern of seismic activity is significant as some kindof precursor.Observations of fault motion at the Yasutomi Observation Tunnel on the Yamasaki faultare explained as a model work using microearthquakes.Finally, a new telemetric observation system for microearthquakes at this Institute isintroduced.
