The already-derived single-layer crustal models do not seem to be consistent with observed gravity and surface wave data. Alternative structures with double layered or three-layer crust are presented for all the regions by the re-interpretation of travel time data. Comparison of theoretically-predicted values with the observations favors a three-layer solution for western and central Japan, suggesting the existence of a lower crustal layer and a thick intermediate layer over the mantle. A high Poisson\u0027s ratio would occur in the intermediate and the upper mantle under central Japan including the Chubu mountain region. In eastern Japan, it is not certain whether there is a thin intermediate layer or not, but the average crustal density might be slightly smaller than that in other regions. The depths to the base of the lower crust are estimated to be 32-35 km in the Tohoku, 27-31 km in the southeast Kwanto, 38-40 km in the northwest Kwanto, 36-40 km in the Chubu, 28-30 km in the Kinki, and 25-28 km in the Chugoku regions respectively. The average crustal structures in Japan and North America are compared.", "subitem_description_type": "Abstract"}, {"subitem_description":
