Abstract:
The numerical simulation of strong ground motion (SGM) based on the physics of rupture
propagation is of prime importance in earthquake engineering for the prediction of site-specific
ground motion, cost effective earthquake resistant designs and assessment of vulnerability and
risk. The development of an efficient numerical method for SGM prediction is must for the
future earthquake engineering since the available empirical relations and simulation methods
like stochastic metod and empirical Green's method do not provide the characteristics of the
individual seismic phases, particularly in the basins and shallow earthquake cases. Further, the
SGM recorders do not prove the characteristics of very low frequency ground motion,
particularly in the case of very large earthquakes. Furthermore, there is lack of SGM records
in the epicentral zone of great earthquakes. Earthquake source dynamics provides key elements
for the prediction of ground motion, and to understand the physics of earthquake initiation,
propagation, and healing. A physical understanding of the spontaneous rupture process is
important for advancing our understanding of earthquake physics.
