dc.description.abstractWe evaluate a probabilistic seismic hazard analysis (PSHA) for the Chiang Mai basin (Thailand), to assess the impact of site response characterization on hazard estimates. The effect of a basin amplification factor introduced in NGA West 2 ground motion models (GMMs) is presented based on the available shear wave velocity profile from microtremor measurement. In addition, 1D amplification related to stratigraphic conditions is considered with the associated uncertainties, and their impact on the hazard is analyzed through a sensitivity analysis. The results provide a good comparison between empirical GMMs and a conventional study, highlighting the importance of ground amplification effects in hazard assessment.
