Map of the study area. Red areas indicate strong ground motion, where the seismic intensity of the main shock of the 2016 Kumamoto earthquake was in the upper 6 range on the JMA scale (Japan Meteorological Agency 2019a). Dark blue lines indicate surface ruptures formed during the earthquake (Shirahama et al. 2016). Light blue lines indicate the three major river systems in the study area: Kichichi River system (KK-R), Shira River system (SR-R), and Midori River system (MD-R). Solid triangles indicate weather stations: Kumamoto Local Meteorological Observatory (KMMT) and Aso-otohime Automated Meteorological Data Acquisition System (ASOT). Solid squares indicate streamflow rate observation stations: SNO, HRS, JNN, YTG, DIR, JON, MFN, and CKB. Solid circles indicate observed springs: a:YKI, b:TNB, c:KYH, d:IKN, e:SOY, f:SOI, g:YSM, h:SMR, i:TDR, j:MTR and k:DMZ. The background map was derived from the Geospatial Information Authority of Japan (2019)
