“…In contrast, as an alternative, seismic loss estimation models are much time efficient and have been widely used to assess earthquake loss. 2,3 Accurate seismic input is the premise of these analytical methods to have a precise loss assessment. Usually, seismic records can be obtained from seismic network in real time.…”

Summary Identification of earthquake ground motion from structural health monitoring (SHM) data provides a good means to reconstruct seismic loads that are essential for postearthquake safety assessments and disaster simulations of structures. Because the data measured by an SHM system are structural absolute response, they cannot be directly applied to the structural motion equation, which is established in relative coordinate system. As such, this paper originally derives the motion equation in absolute coordinate system and then expands the equation into modal space. In addition, the proposed method allows for identifying earthquake ground motion using incomplete modal information and limited measurements through the standard Kalman filter. Subsequently, a numerical two‐dimensional frame is used to validate the feasibility of the proposed method, and the influences of modal parameters and measurement noise on the identification accuracy are also fully investigated. The results show that the proposed method is sensitive to frequency and measurement noise but insensitive to modal shape and damping ratio. It is also found that the identified ground motion subjected to certain measure noise can still be reliably employed for postseismic response calculations of medium‐ and long‐period structures. Finally, a shaking table test performing on a five‐floor frame further demonstrates the effectiveness and accuracy of the proposed identification algorithm for practical application.

“…Every attempt has been made to utilize the best data available, but semi-empirical fatality estimations remain a fundamentally uncertain process and will not be perfectly accurate. Yet there is ample evidence to suggest that fatality estimations remain a useful procedure for determining disaster scale and response capacity needs (Wyss, 2004;Erdik et al, 2011;Jaiswal et al, 2011b). The US Geological Survey provides the following estimates for response levels at varying earthquake fatality thresholds:…”

Abstract. The influx of millions of Syrian refugees into Turkey has rapidly changed the population distribution along the Dead Sea Rift and East Anatolian fault zones. In contrast to other countries in the Middle East where refugees are accommodated in camp environments, the majority of displaced individuals in Turkey are integrated into local cities, towns, and villages -placing stress on urban settings and increasing potential exposure to strong earthquake shaking. Yet displaced populations are often unaccounted for in the census-based population models used in earthquake fatality estimations. This study creates a minimally modeled refugee gridded population model and analyzes its impact on semi-empirical fatality estimations across southeast Turkey. Daytime and nighttime fatality estimates were produced for five fault segments at earthquake magnitudes 5.8, 6.4, and 7.0. Baseline fatality estimates calculated from census-based population estimates for the study area varied in scale from tens to thousands of fatalities, with higher death totals in nighttime scenarios. Refugee fatality estimations were analyzed across 500 semi-random building occupancy distributions. Median fatality estimates for refugee populations added non-negligible contributions to earthquake fatalities at four of five fault locations, increasing total fatality estimates by 7-27 %. These findings communicate the necessity of incorporating refugee statistics into earthquake fatality estimations in southeast Turkey and the ongoing importance of placing environmental hazards in their appropriate regional and temporal context.

“…The classification system selected to characterize buildings by the level of damage or loss would enable an integrated analysis of seismic risk. There are a number of parameters that are effective in determining the risk of earthquake damage for any structure [33][34][35][36][37]. Table 1.…”

The possibility of creating an "ID card" for each new and existing building in urban areas, based on transfer of necessary data into electronic format, is analysed in the paper. Local governments, public institutions, organizations, and building owners are thus able to obtain parametric information about the building using smart phones or tablets. Thanks to QR application, the access to building Inventory under seismic impact has become extremely fast and easily accessible via smart phones and tablets. The proposed IOS/ Android system greatly reduces the need to go through administrative formalities to obtain information and documents relating to an earthquake-prone building.
