A displacement of maxima will correspond to the dip orientation.
Relationships between several environmental factors (e.g. bedrock classes, surface deposits, elevation, slope, aspect, dip, dip orientation and relation between dip and slope) and land use changes were appraised.
If the slope angle of the initial surface was greater than 7°, the compression induced only one group of thrusts with a dip orientation contrary to the original compression direction.
Former foreshore deposits are mapped in dip-orientation beneath modern backshore regions using ground-penetrating radar, documenting the nature of beach progradation.
The results show that if the initial surface was horizontal or the slope angle was smaller than 7°, the compression induced two groups of thrusts with opposite dip orientations.
According to NIED (2016) and Kyushu University (2016), the hypocenters align along a west-dipping orientation in the central part of the Hinagu fault, while in the northern part, where the hypocenter of M j 6.5 is located, the distribution extends slightly deeper toward the east rather than to the west.
Six sets of discontinuities common to all sites were identified and statistically characterised (dip, strike, orientation, density, size, and estimated transmissivity).
The obtained displacement field is consistent with a right-lateral motion along the Hinagu fault, and thus, the rake was assumed to be a right-lateral with no constraint on dip-slip orientation.
Object dip and orientation was measured with a Brunton compass.
In fact, the orientation of this fault plane shows further complexity as oriented at an oblique angle with the overall orientation of the mainshock fault plane dipping down to ESE (Fig. 4).
