Abstract

We utilize receiver functions from ten broadband seismic stations deployed along a north–south profile traversing the Indo‐Gangetic plains in northern India to investigate the sedimentary thickness variations in this hitherto less‐studied foreland basin south of the Himalaya. Parameterization of the velocity structure adopting the neighborhood algorithm approach shows that the data can be satisfactorily modeled for low‐velocity sediments having shear‐wave velocities in the range of 0.72–2.5  km/s with thicknesses varying from 0.5 to 3.7 km beneath the individual stations. The velocity–depth functions obtained in this study are important for earthquake‐hazard assessment of the densely populated urban centers spread over this region, in terms of predicting strong ground motions due to large earthquakes in the Himalaya.
