Regardless of numerous paleoseismological studies along the active front Himalayas, it still lacks precision with respect to earthquake recurrence, rupture, slip mechanism, etc. which hinders understanding region's seismic hazards. Considering hazard posed by previous Himalayan earthquakes, for instance, from Kashmir, Chamba, Kumaun-Garhwal, Nepal, etc., becomes vital identify seismogenic structures and length rupture that might be affected in near future. In present study, investigation is carried out ∼150 km long Back Thrust (BT) Frontal bounding northern limb Janauri Anticline (JA) northwest frontal Himalaya. By taking advantage optically stimulated luminescence (OSL) dating technique, study reports three newly identified events BT i.e. 535-1269 AD Event I, 1447–1636 II, 1660–1929 III. Our findings at Palahta locality Punjab state complement, i.e., (Event II), effectiveness previously more recent (MRE) Hajipur, further suggest ∼97km BT. The other results on timing I III) are well thought considered here as independent. Such independent tend fill an important gap database provide us opportunity explore paleoseismic detail Himalayas. a well-established would assist better estimation will directly influence long-term planning infrastructure development regions like
