A source-partitioned framework for hazard-consistent site response and probabilistic liquefaction assessment of deep alluvial deposits under bimodal seismic hazard

This dataset supports the article "A source-partitioned framework for hazard-consistent site response and probabilistic liquefaction assessment of deep alluvial deposits under bimodal seismic hazard" (submitted to Acta Geotechnica). It covers 53 grid points and the town of Kaiserganj, Bahraich district, on the deep alluvium of the central Indo-Gangetic plain, India. The dataset contains the following.1. SPT borehole data (52 boreholes, 971 samples) and MASW shear-wave velocities.2. Rock hazard curves (Vs30 = 760 m/s) for PGA and 12 spectral periods, split into total, local-fault and Himalayan source groups, with uniform hazard spectra, deaggregation results and conditional mean spectra.3. Soil columns extended to engineering bedrock at 30, 100, 150 and 200 m.4. Stochastic finite-fault simulated seed motions and 70 spectrum-matched input motions.5. Results of 3024 equivalent-linear site response analyses (surface spectra, PGA and maximum strain).6. Hazard-consistent surface uniform hazard spectra.7. Liquefaction results for every analysis, lognormal fragility parameters, and annual rates, return periods and 50-year probabilities of triggering and LPI exceedance by source group. Accelerations are in g, periods in s, depths in m and velocities in m/s. Recorded accelerograms are not redistributed but are available from PESMOS (IIT Roorkee), Takai et al. (2016) and the U.S. Geological Survey.
