内容記述 | Spatial and temporal features of the seismicity of the Izu area, central Japan for the past 80 years have been studied on the basis of a newly prepared catalog of shallow earthquakes of M≧5.4. This area is characterized by relatively frequent occurrence of foreshock sequences and earthquake swarms. A peculiarity of the seismicity is the occurrence of swarm-like sequences with exceedingly large main shocks. This type of sequence cannot be classified among the three types proposed by Mogi in 1963 and is called here an ""earthquake sequence of type 4"". The shallow earthquakes are divided into four classes according to the values of M-MI, where M is the magnitude determined from the maximum amplitudes recorded by medium-period seismographs used in the JMA network and MI is the magnitude determined from the size of the area in which it is felt. Such a classification seems to be useful in the discrimination of foreshocks from earthquake swarms. | |||||
