**4. Relationship between fault displacements and drainage offset**

Conventionally, quantitative displacement in a fault zone has been demonstrated by an offset of the river channel [25, 44, 45]. Usually, it has been widely observed that the maximum displacement occurred in the central part of the fault zone [46] and that the displacement decreases with increasing length. Decrease of river offset towards the west is possibly, westward propagation of the faults. These streams were taken into account to calculate offset ratio:

$$a = D/L\tag{6}$$

where *D* is the amount of stream offset along fault and *L* is upstream length of the displaced stream [47]. A relationship between long-term slip rate (S) along the lateral slip of a fault and offset ratio (*a* = *D/L*) has been roughly calculated as S (m/1000 years), *i.e.,* 10 *a* [25, 44, 45].

We investigated the major to north flowing rivers such as the Suvai, Bhimguda, Narelawali, Dhadawali, Karaswali, Malan, Baniyo, and Dabhodanwari rivers and adjoining streams to estimate river offset along the E-W faults F1–F4 (GF). However, 17 south flowing rivers such as 1–8, Khalwa River (9), 10, 11, Sharan Nadi (12), and rivers 13–17 have been analyzed to estimate offset along faults F6–F8. Based on offset of river channel we estimated net displacement along F2–F10 respectively.
