Seismic risk mitigation is a worldwide concern and the development of effective mitigation strategies requires sound seismic hazard assessment. The purpose of seismic hazard analysis is to provide a scientifically consistent estimate of seismic ground shaking for engineering design and other considerations. The performances of the classical probabilistic approach to seismic hazard assessment (PSHA), currently in use in several countries worldwide, turned out fatally inadequate when considering the earthquakes occurred worldwide during the last decade, including the recent destructive earthquakes in Haiti (2010), Chile (2010) and Japan (2011).
Therefore the need for an appropriate estimate of the seismic hazard, aimed not only at the seismic classification of the national territory, but also capable of properly accounting for the local amplifications of ground shaking (with respect to bedrock), as well as for the fault properties (e.g. directivity) and the near-fault effects, is a pressing concern for seismic engineers.
A remarkable example of fruitful collaborations established within EU-IndiaGrid is the activity performed on the EU-IndiaGrid computing infrastructure by the ICTP/SANDs group and their Indian partners (Institute of Seismological Research (ISR), in Gujarat and the CSIR Centre for Mathematical Modelling and Computer Simulation (C-MMACS) in Bangalore) in the area of advanced seismic hazard assessment in the Indian region of Gujarat.
