Fig. 4From: Detection of plastic strain using GNSS data of pre- and post-seismic deformation of the 2011 Tohoku-oki earthquakeConceptual model of the time development of stress in the upper crust of inland Japan. The diagram follows Ikeda (1996) with a modification of the zero stress level; the stress just after a gigantic earthquake was taken to be zero in his original diagram. Ikeda (1996) considers that the stress increase is suppressed by the occurrence of intraplate earthquakes before a gigantic earthquake at subduction zoneBack to article page
