微小地震観測網で決定した近畿周辺の深発地震

抄録

By using the data of recently developed Microearthquake Observatory net, we can determine the hypocenters of deep focus earthquakes exactly. Focal planer zones are found to be more thiner than the ones determined hitherto, for example, those of the earthquakes (T) near Takayama, Gifu Prefecture and (W) near The Wakasa Bay is ten and a few km thick. The distribution of hypocenters in the north area of Kinki district are different from those in the south: the former is discontinuous, but the latter is continuous distribution.
