The age of a fault can be determined through various methods, including radiometric dating of rocks along the fault line, analysis of the offset of geological features or structures, and dating of the sediments or rocks that have been deformed by the faulting process. Additionally, relative dating techniques such as cross-cutting relationships and stratigraphic principles can also be used to determine the sequence of events involving the fault.
The rock age of a normal fault can be determined by analyzing the age of the rocks on either side of the fault. Normal faults typically form in response to extensional forces, where older rocks are uplifted and younger rocks are deposited in the hanging wall. By dating the rocks on either side of the fault, geologists can determine the relative timing of fault movement.
Cross cutting
Fossils can be used to determine the relative age of rock layers by comparing the types of fossils found in different layers. Fossils of organisms that existed for a short period of time can be used to date layers of rock containing them. Geologic features such as fault lines and unconformities can also help determine the relative age of rock layers by showing where layers have been disturbed or eroded.
The Law of Cross-Cutting Relationships would be used here. If a fault cuts across a rock unit, it is younger than that rock unit. If a fault cuts across a series of rocks, but suddenly stops at a rock unit, then that rock unit which the fault stops at is younger than the fault. So let's say the order of rocks (from top to bottom), is A B C D. If the fault cuts across B C and D, but not A, then the age of the fault is sometime between A and B. If you know the absolute ages of A and B (let's say, rock A is 100 million years old and rock B is 200 million years old), then the age of the faulting is between 100 and 200 million years ago.
Geologists generally know the age of a rock by determining the age of the group of rocks, or formation, that it is found in. The age of formations is marked on a geologic calendar known as the geologic time scale. Development of the geologic time scale and dating of formations and rocks relies upon two fundamentally different ways of telling time: relative and absolute.

The severity of the damage does not determine fault. The facts of the loss and the point of impact will help determine fault.
Relative age is used to determine the age and how old a geological feature or fossil.

There are two methods used to determine the age of a rock or fossil. The first is carbon dating and the second is radiometric dating.
fault location can be provided by microprocessor based relays or targets (multiple INST overcurrents are sometimes used to determine rough location).
