A set of 3D physics-based numerical simulations (PBS) of possible earthquakes scenarios in Istanbul along the North Anatolian Fault (Turkey) is considered in this article to provide a comprehensive example of application of PBS to probabilistic seismic hazard (PSHA) and loss assessment in a large urban area. To cope with the high-frequency (HF) limitations of PBS, numerical results are first postprocessed by a recently introduced technique based on Artificial Neural Networks (ANN), providing broadband waveforms with a proper correlation of HF and low-frequency (LF) portions of ground motion as well as a proper spatial correlation of peak values also at HF, that is a key feature for the seismic risk application at urban scale. Second, before application to PSHA, a statistical analysis of residuals is carried out to ensure that simulated results provide a set of realizations with a realistic within-and between-event variability of ground motion. PBS results are then applied in a PSHA framework, adopting both the "generalized attenuation function" (GAF) approach, and a novel "footprint" (FP)based approach aiming at a convenient and direct application of PBS into PSHA. PSHA results from both approaches are then compared with those obtained from a more standard application of PSHA with empirical ground motion models. Finally, the probabilistic loss assessment of an extended simplified portfolio of buildings is investigated, comparing the results obtained adopting the different approaches: (i) GMPE, (ii) GAF, and (iii) FP. Only FP turned out to have the capability to account for the specific features of source and propagation path, while preserving the proper physically based spatial correlation characteristics, as required for a reliable loss estimate on a building portfolio spatially distributed over a large urban area.

“…For example, in the Mw7. 6 Izmit earthquake, 10 hospitals sufered severe damage, which led to a large-scale emergency transfer of casualties [4]. In the Mw8.0 Wenchuan earthquake, because several hospitals were damaged, the medical rescue had to be carried out in temporary hospitals [5].…”

The healthcare system is the bearer of treating the wounded and the victims of earthquakes. The functional integrity of the healthcare system is critical to the process of postearthquake medical rescue. Thus, the requirements for seismic resilience of the medical functions of the healthcare systems are increasing. Many studies have applied resilience research to address critical issues in the medical rescue of postearthquake casualties, such as medical diagnosis, emergency surgery, and intensive care. However, systematic construction is still lacking. System resilience is one of the most promising systemic management theories with great potential to address the abovementioned challenges. This article puts forward a scientific concept that system resilience can improve the efficiency of earthquake relief in medical rescue. Firstly, a scientific review of medical demand and medical resilience was conducted, summarizing resilience and resilience of healthcare system concepts. In addition, the postearthquake medical demand was reviewed, and the classification and distribution probability of postearthquake injuries were summarized. Furthermore, by reviewing the postearthquake medical rescue process, the weak points of each medical link were summarized. Combined with the key points in the medical rescue process, the application of resilience studies in the medical system is reviewed, and the progress of medical resilience is illustrated. In summary, combined with medical demand, the article provides some guidance for the deep integration between medical rescue processes and medical resilience and identifies the challenges of system resilience to reduce the waiting time of the injured future medical rescue in the earthquake.
