Imtiyaz A. Parvez

Centre for Mathematical Modelling and Computer Simulation, India

Dr Parvez’s seminal contributions include quantification of seismic hazard in the Indian subcontinent, in terms of expected ground accelerations based on rigorous source modeling and computer simulation, incisive experiment design and intensive field investigations. These resulted in the creation of the first deterministic seismic hazard map of the country and have since been greatly elaborated both in a progressive enrichment of the scientific approach and experiment based hazard quantification of specific metropolises, notably Delhi. In particular, Dr Parvez made notable contributions to the computational approaches and practice of quantifying strong ground motion at a site towards microzonation of seismically vulnerable areas, using two dimensional models incorporating laterally inhomogeneous media and rupture processes of earthquake generation. Thus, for example, he showed the importance of distance from an earthquake source in evaluating ground motion for microzonation of an area, an effect usually neglected in extant approaches to this work. Furthermore, recognizing the essentially stochastic nature of earthquakes, Dr Parvez used the Bayesian statistics to analyze the seismo-tectonics of northeastern India. More recently, he has been engaged with the outstanding problem of calculating thresholds of ground motion at bedrock-level beneath Delhi city, that would not be exceeded due to an earthquake in the seismic gap of Central Himalaya, just ~300 km to the north.
