A road collapsed near a JR Senseki Line (a commuter rail route in northeastern Japan) level crossing in Ishinomaki, Miyagi Prefecture, early on the 21st, trapping a passenger car in the sinkhole. Authorities believe a water main cracked during recent seismic activity, causing underground leakage that eroded the road surface. JR suspended train services on the affected section while water utility crews and railway staff worked to restore the area.
