Building upon a long experience of successful practice with DSHA, NDSHA now convolves a comprehensive physical knowledge of: (i) seismic source process; (ii) propagation of earthquake waves; (iii) combined interactions with site conditions—and thus effectively accounts for the tensor nature of earthquake ground motions. Standard NDSHA, using geological and geophysical data, computationally estimates an envelope of scenario ground-shaking characteristics from both: (1) the largest historically observed earthquake within a region; and (2) also from the Maximum Credible Earthquake MCE5. Because each scenario is always “a real earthquake”, it therefore does not require considerations of either probabilistic hazard model temporal representations of earthquake “likelihood”, or scalar empirical GMPEs.
Some NDSHA applications performed at an international level will be presented, together with some preliminary results for ground shaking scenarios in the Vancouver Island and mainland areas (https://www.xeris.it/Methodology/index.html). Earthquakes and Sustainable Infrastructure5 presents a new NDSHA paradigm for seismic safety - detailing in one volume the ‘state-of-the-art’ scientific knowledge on earthquakes and their related seismic risks, and the actions that can be taken to reliably ensure greater safety and sustainability. Thirty chapters of the book provide comprehensive reviews and updates of NDSHA research and applications so far in Africa, America, Asia and Europe— evidences and case histories illustrating the overall prediction accuracy of NDSHA and its robust validation for real-world applications leading to more reliable procedures for seismic hazard assessment evaluations.
