A remarkable vertical crustal movement was found to have a wavelength of several kilometers by the relevelings in 1978. The anticlinal uplift and the corresponding synclinal subsidence with a noticeable asymmetric feature about the fold axes were found to be concordant with the underlying Neogene and Quaternary fold structures. The fault plane solution of a local earthquake located in the area shows a high angle reverse faulting with the strike in a NNE-SSW direction parallel to the fold axes as confirmed for the active faults in the area. The result shows a common feature to the source mechanism of big earthquakes in the inner belt of Northeast Japan represented by the Niigata earthquake of 1964. Considering the seismotectonic environment in the area, the releveling data was analysed by applying the static dislocation theory. It was found from the analysis that the asymmetric mode of movement could be explained by a reverse faulting in the interaxial zone of fold structure as expected from the seismological evidences. The preferred fault parameters of the model were as follows: a rectangular surface of horizontal length 10 km, width 4 km, dip 85° embedded in an elastic half space with the top of the fault at a depth 1 km below the earth's surface and dip slip motion 2.5 cm on the fault surface with the strike in a NNE-SSW direction. The seismic moment MoL=3.3×1023 dyne・cm was obtained from the fault parameter determination. Cummulative seismic moment Σ Mos from a magnitude-moment relation was estimated from the seismicity data for the specified folded area in the period corresponding to the releveling data.
