Corrections to the coseismic deformation pattern revealed by GPS data

In "GPS data support the inelastic deformation", I stated that only the NW corner is anomalous. This was wrong, when I looked closely the results by S.-B. Yu who visited ERI on Oct. 22 after the Tsukuba symposium. The direction and the amount of the horizontal vectors change gradually from the south to the north, i. e., from 3 m to 7 m in amount, and from WNW to NNW in direction. This cleary indicates that some inelastic deformation occurred within the accretionary prism itself, though I have not found any explanation yet
