Richter scale
Well, first off, nobody actually uses the Richter scale anymore, the most common scale is the Moment Magnitude Scale. So that would be one way. There are other scales as well.
first find out least count of main circular scale in degrees,then divide least count of main scale by total divisions on cylindrical scale(this cylindrical scale works as vernier scale for fist one,its least count will be in minutes) then further divide least count of cylindrical scale by total divisions of small vernier scale which touches it,(this small scale works as vernier scale for cylindrical scale and its least count will be in seconds).
The methods the geologists used when they first developed the geologic time scale. Were studying rock layers and index fossils worldwide. By Patrick
