Figure 1From: Contributions of poroelastic rebound and a weak volcanic arc to the postseismic deformation of the 2011 Tohoku earthquakeTectonic setting and postseismic GPS observations in NE Japan. (a) Horizontal displacements. Red arrows represent 2-year GPS observations since the 2011 Tohoku earthquake. The solid magenta circle represents the location of the example GPS station whose time series is presented in Additional file 1: Figure S1. Solid black triangles represent active volcanoes. (b) Vertical displacements of GPS stations 2 years after the 2011 earthquake. Black contours at 5-meter intervals show the coseismic slip distribution from Iinuma et al. (2012).Back to article page
