From: Seasonal and transient surface displacements in the Kumamoto area, Japan, associated with the 2016 Kumamoto earthquake: implications for seismic-induced groundwater level change

Fig. 1

a Location of the Kumamoto area. b The general groundwater flow path (blue arrows) overlaid on topography. Groundwater flow path (blue arrows) is based on Kumamoto Prefecture (1995). Black square is the location of the city of Kumamoto, and black circles indicate the locations of GNSS stations (Kumamoto (North station) and Jonan (South station)). Dashed rectangle is the area of interest. G1, G2 an G3 indicate the locations of groundwater wells plotted in Fig. 8. Black lines indicate surface ruptures associated with the 2016 Kumamoto earthquake based on Toda et al. (2016). A black triangle is the reference location of PSI analysis. The focal mechanism for the foreshock (Mw 6.2) and mainshock (Mw 7.0) was derived by F-net managed by the National Research Institute for Earth Science and Disaster Resilience (Asano and Iwata, 2016)
