We attempt to model the GPS displacements consisting of two elements, the right-lateral relative movement at a rate of \uff5e2cm/yr between the northeast and the southwest Japan blocks and a locking fault in the upper crust along the Niigata-Kobe tectonic line. Subtracting the block movements from the GPS displacements yields a new data set of surface displacements, for which we make a geodetic inversion to obtain a backslip model of a left-lateral normal fault with the strike direction N43\u00b0E, the dip direction of -43\u00b0, the rake angle of 124\u00b0, the depth of the lower edge of 20 km, and the slip rate of \uff5e2.9 cm/yr. Superposing the right-lateral block movements on the displacements produced by the backslip fault model recovers the original GPS displacements and a dislocation on the backslip fault becomes zero. The backslip fault turns to be the locking fault in this final situation. This model produces a compressional stress field with the direction NW-SE and a magnitude of \uff5e10kPa/yr at a depth range of 0\uff5e10 km, which is qualitatively consistent with the anomalous compressional stress direction in the Hida mountains obtained by focal mechanisms. Based on the modeling, we propose the working hypothesis that the Niigata-Kobe tectonic line currently plays the role of the plate boundary between the Okhotsk (the northeast Japan) and the Amurian plates (southwest Japan blocks), instead of the Itoigawa-Shizuoka tectonic line.", "subitem_description_type": "Abstract"}]}, "item_4_full_name_3": {"attribute_name": "\u8457\u8005\u5225\u540d",
