The Persey Fault begins just north of Lake Persey in Allay County, Lohana. The fault then proceeds to slice through the lake, and, shortly afterwards, cross State Route 346 just south of Haraf. The fault line then turns from east to southeast, continuing into Senardo County and passing just north of the city of Townsmont. The fault passes through southwestern Senardo County, and then enters Northampton County. The fault passes to the north of the town of La Domain. The fault ends in northern Northampton County.
