Title: Seismic hazard evaluation of the Oman India pipeline

The proposed Oman India pipeline will traverse approximately 1,135 km of the northern Arabian Sea floor and adjacent continental shelves at depths of over 3 km on its route from Ra`s al Jifan, Oman, to Rapar Gadhwali, India. The western part of the route crosses active faults that form the transform boundary between the Arabian and Indian tectonic plates. The eastern terminus of the route lies in the vicinity of the great (M {approximately} 8) 1829 Kutch, India earthquake. A probabilistic seismic hazard analysis was used to estimate the values of peak ground acceleration (PGA) with return periods of 200, 500 and 1,000 years at selected locations along the pipeline route and the submarine Indus Canyon -- a possible source of large turbidity flows. The results defined the ground-shaking hazard along the pipeline route and Indus Canyon for evaluation of risks to the pipeline from potential earthquake-induced geologic hazards such as liquefaction, slope instability, and turbidity flows. 44 refs.
