Abstract (English)

This study developed an annualized earthquake loss (AEL) map for selected hospitals of specific building typologies in Manila City, Philippines to assess seismic risk and aid in earthquake mitigation planning. Using the OpenQuake engine, Probabilistic Seismic Hazard Analysis (PSHA) and classical damage assessment were conducted. Hospital building typologies, including year of construction, storeys, and location, were acquired through GIS tools and used to evaluate the exposure. Philippine-specific fragility curves and locally-fit logic trees of Ground Motion Prediction Equations and seismic source models were applied to estimate losses over a 50-year investigation period, with intensity measure levels from 0.01g to 1.0g. Results revealed that Hospital K incurred the highest annualized losses of around 42 Million PHP, followed by Hospital G with 36 Million PHP and Hospital I with 19 Million PHP. The total annualized loss for all selected hospitals in Manila City amounted to approximately 139 Million PHP and were consolidated into a single AEL map. These values can guide local authorities and hospital administrators in enhancing seismic risk mitigation and disaster preparedness, emphasizing the need to strengthen hospital resilience. The AEL map can also be expanded by other Metro Manila cities to assess the entire National Capital Region and compare hospital AELs per city.

Abstract (Filipino)

Ang pag-aaral na ito ay bumuo ng isang annualized earthquake loss (AEL) map para sa piling mga ospital na may tiyak na uri ng estruktura sa Lungsod ng Maynila, Pilipinas, upang masuri ang panganib sa lindol at makatulong sa pagpaplano para sa mitigasyon. Gamit ang OpenQuake engine, isinagawa ang Probabilistic Seismic Hazard Analysis (PSHA) at classical damage assessment. Ang mga katangian ng ospital, kabilang ang taon ng pagkakagawa, bilang ng palapag, at lokasyon, ay nakuha gamit ang mga GIS tool at ginamit sa pagtaya ng exposure. Gumamit ng mga fragility curve na akma sa Pilipinas at mga locally-fit logic tree ng Ground Motion Prediction Equations at seismic source models upang tantiyahin ang mga loss sa loob ng 50-taong panahon ng pagsusuri, na may intensity measure levels mula 0.01g hanggang 1.0g. Ipinakita ng mga resulta na ang Hospital K ang nagkaroon ng pinakamataas na annualized loss na humigit-kumulang 42 milyong PHP, sinundan ng Hospital G na may 36 milyong PHP at Hospital I na may 19 milyong PHP. Ang kabuuang annualized loss para sa lahat ng napiling ospital sa Lungsod ng Maynila ay tinatayang nasa 139 milyong PHP at pinagsama sa isang AEL map. Maaaring gamitin ang mga halagang ito upang gabayan ang mga lokal na awtoridad at administrador ng ospital sa pagpapabuti ng seismic risk mitigation at disaster preparedness, na binibigyang-diin ang pangangailangan na palakasin ang katatagan ng mga ospital. Maaari ring palawakin ang AEL map sa iba pang lungsod sa Metro Manila upang masuri ang buong National Capital Region at maikumpara ang AEL ng mga ospital kada lungsod.
