Fig. 1

Observed postseismic displacements and strain field, cumulative over 5 years. a Displacement field. Black arrows and contoured color map represent the 5-year cumulative horizontal and vertical displacements from onshore GNSS data, respectively. Open arrows and blue/red arrows represent 4-year cumulative horizontal and vertical displacements from offshore SGO data, respectively. The outlined area of Fig. 6 is also indicated by dashed lines. The green diamond denotes the GNSS site from which the time series displayed in (c) was obtained. The broken line denotes the plate boundary. b Principal strain axes and dilatational strain calculated from the horizontal displacements only, using the onshore GNSS data shown in (a). Arrows and contoured color map represent the 5-year cumulative principal strain axes and dilatational strain, respectively. c Time series of observed (black) and modeled (brown) vertical displacements at GNSS site (Iwaizumi3: 020905), the location of which is shown in (a)
