Item type:Publication, Open dataset of road obstructions due to collapsed buildings from the 2023 Turkey earthquakes(International Association for Earthquake Engineering, 2024-01-01)After large-magnitude earthquakes, collapsed buildings can disrupt transportation networks due to debris obstructing streets, sidewalks, and highways. These disruptions can critically compromise rescue activities, the mobilization of seriously injured patients, and aid distribution to the affected population. Accordingly, it is recommended the removal of obstructions during the first 48 hours after a disaster to meet emergency response needs as quickly as possible. However, the literature on seismic vulnerability has yet to deeply address the topic of road obstructions due to the limited availability of data. In this paper, we exploit several open datasets to collect about 1,400 collapsed buildings causing varying levels of road obstructions after the 2023 Turkey, earthquake sequence. The buildings are located in Hatay, Islahiye, Adiyaman, and Kahramanmaras. From visual inspection of high-resolution satellite and aerial images, the buildings were geolocated and classified according to the level of obstruction produced in the road by its debris. In the study, we considered three levels of obstruction: no obstruction, partial obstruction, and complete obstruction of a road. The number of floors was recorded from Google Street View data. Analysis of the data shows that taller buildings that experienced full collapse produced more obstructions. Thus, researchers can utilize the dataset to develop probabilistic models that predict the obstruction level according to the type of construction, the number of floors in a building, and the damage level. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Vertical growth of masonry buildings in Peru and its role in the increase of seismic vulnerability(International Association for Earthquake Engineering, 2024-01-01)In Lima, the capital of Peru, and many cities in South America, houses tend to grow vertically. Due to financial limitations and increment of family members, houses increase a floor at different periods. As a result, their dynamic properties and performance during earthquakes change over time. Thus, it is necessary to estimate the change in the seismic vulnerability considering the height change in time. Unfortunately, today, there is no information regarding the vertical growth rate of buildings in Lima. To this aim, we have estimated the vertical growth rate of informal masonry buildings by inspecting 457 samples. The selection of the buildings was based on their availability in the Google Street View dataset, which was used to identify the number of floors in 2013. Then, the number of floors in 2023 was determined by a series of field surveys. With the number of floors at the two dates, we compute the transition matrix T. The relevance of the transition matrix lies in that it can be used to predict the number of floors in different years and assess the change in the seismic vulnerability of masonry buildings. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Placing engineering in the earthquake response and the survival chain(Nature Research, 2024-12-01)Earthquakes injure millions and simultaneously disrupt the infrastructure to protect them. This perspective argues that the current post-disaster investigation paradigm is insufficient to protect communities’ health effectively. We propose the Earthquake Survival Chain as a framework to change the current engineering focus on infrastructure to health. This framework highlights four converging research opportunities to advance understanding of earthquake injuries, search and rescue, patient mobilizations, and medical treatment. We offer an interdisciplinary research agenda in engineering and health sciences, including artificial intelligence and virtual reality, to protect health and life from earthquakes.
