Post-earthquake hospital functionality evaluation: The case of Kumamoto Earthquake 2016

金沢大学理工研究域地球社会基盤学系The Japanese Prefecture of Kumamoto experienced a series of strong earthquakes in April 2016 causing widespread damage and had a serious impact on local communities. The events caused over 3000 casualties and affected the continuity of healthcare services. Many hospitals had to be evacuated but the reasons for this evacuation are not clear. This research aims to investigate the impact of damage on the performance of the healthcare service through a survey of 118 healthcare facilities. The study connects earthquake metrics and the loss of healthcare service functionality and reveals the reasons for which facilities were totally or partially evacuated. Findings suggest that the reasons are mainly damage to buildings, critical systems, and medical equipment. It concludes by estimating that the stricken areas lost approximately 15% of their healthcare functionality. The study also concludes that the current building standards increased the performance of hospital buildings by approximately 10%; however, more attention is needed to protect architectural and critical systems. © The Author(s) 2020
