“…The functional form of both GMPEs is similar, and therefore, their predictions do not differ significantly, as observed in previous studies (e.g., Hussain et al, 2020;Gómez-Zapata et al, 2022a). In particular, Hussain et al ( 2020) found negligible differences in direct loss estimates for the residential building stock of Santiago de Chile after using these two GMPEs to simulate the associated ground motion from subduction earthquake scenarios.…”

“…We employ the Bayesian exposure model of the building stock with the building classes described in (Gómez-Zapata et al, 2022a) and available in (Pittore et al, 2021a). The model was constructed by taking the OpenStreetMap footprint of the buildings in the two communes, and assigning to each footprint the most likely building class.…”

“…6. Detailed building counts for each class are presented in (Gómez-Zapata et al, 2022a) The model considers 16 building classes (Gómez-Zapata et al, 2022a), which correspond to the building classes proposed in the SARA project (Yepes-Estrada et al, 2017), and have an associated replacement cost. Furthermore, each building class has an associated fragility model with five damage states (Villar-Vega et al, 2017).…”

Abstract. Different risk management tasks, such as land-use planning, preparedness and emergency response, utilize scenarios of earthquake events. A systematic selection of such scenarios should aim at finding those that are representative of a certain severity, which can be measured by its consequences to the exposed assets. For this reason, it has been proposed to define a representative scenario as the most likely one leading to a loss with a specific return period, e.g., the 100-year loss. We adopt this definition and develop enhanced algorithms for determining such scenarios for multiple return periods, based on a seismic catalog. With this approach, we identify representative earthquake scenarios for the Valparaíso and Viña del Mar communes in Chile. Because the earthquake scenarios are defined in terms of the loss exceedance, the scenarios vary in function of the exposed system. In this contribution, we consider separately the residential building stock and the electrical power network, and identify and compare earthquake scenarios that are representative for these systems.

The current research study aims to introduce the experience of implementing a serious game using the concept of game-based GIS approach for crisis management during earthquake disasters. In this study, we aimed to develop a game-based GIS approach and examine its efficiency for simulating earthquake rescue management in Tabriz city. In designing this game, typical scenario-based, game-based GIS methods and techniques were employed, and the proposed approach was applied to crisis management. To achieve this goal, we addressed the technical details regarding the development and implementation of the scenario-based and game-based GIS approach. Based on the results, game-based simulations can be considered an efficient approach for disaster simulation and can improve the skills of rescue teams. The outcome of this application is an intellectual game that almost all users at any age can play, and the game can challenge their ability to solve critical issues. The results are critical for explaining the effectiveness of rescue teams and crisis management facilities. As we intended to develop an approach for the simulation of earthquake disasters and emergency responses, we therefore conclude that the results of this study can also be employed to improve the skills of rescue teams and citizens for dealing with crises resulting from earthquake disasters. As a result of this research, the developed tool is published, together with this paper, as an open source and can be employed for any scenario-based analysis in other case studies. By presenting a-state-of-the-art approach, the results of this research study can provide significant contribution to further the development of GIScience and its applications for disaster and risk mitigation and management.

“…Recently, novel approaches relying on satellite images and/or open-accessible geospatial data have been developed to set up seismic exposure models (Geiß et al, 2017;Gomez-Zapata et al, 2022;Krayem et al, 2021;Nievas et al, 2022;Sousa et al, 2017;Wieland et al, 2012). Particularly, in countries with limited census data and incomplete building datasets, such as Lebanon, volunteered geographic information, such as the data provided by OpenStreetMap (OSM) (https://www.openstreetmap.org/) are valuable resources for the development of up-todate building exposure models (e.g.…”

Estimating urban seismic damages and debris at the building-level: Application to the city of Beirut, Lebanon

The estimation of seismic damages and debris at the urban scale - at a precise building-by-building level- is challenging for several reasons. First, commonly used methodologies for seismic damage estimation rarely take into account the local site effects, precisely at the building-level. Second, the available methods for debris estimation fail to estimate at the same time the quantity of debris generated per building according to its damage level and the distribution of the debris (extent and height) around buildings. Finally, the lack of comprehensive data on the building stock and the relevant building properties and their taxonomy further increases the complexity of assessing possible earthquake consequences at an urban scale. This paper addresses these challenges and proposes improvements to the assessment of seismic damages and debris at the building level, along with the development of a 3D building model based on satellite images and heterogeneous data. These developments, applied to the city of Beirut, Lebanon, highlight the control of the site effects on the seismic damage spatial distribution throughout the city and the large volume and extent of debris to be expected in the city for a strong earthquake.
