Relationship between Earthquake-related Deaths and Building Damage Caused by Earthquakes and Tsunamis

Abstract

This research focuses on the city of Ishinomaki (3277 direct deaths, 276 indirect deaths; the number of deaths accounts for 2% of the total population), which was severely damaged by the 2011 Tohoku Earthquake. The earthquake resulted in 269 casualties. By considering the circumstances of each death, we seek to reevaluate the safety of homes and assess the degree of damage according to place of residence. A total of 31 Disaster Condolence meetings have been held between August 30, 2011 and October 5, 2021. At the time of the earthquake, 58% of victims were at home, 12% at hospitals, 10% at facilities for the elderly, and 17% had no description. Although half of the facilities for the elderly had no building damage, there were disruptions to lifelines and lack of care. 40% of the hospitals were flooded and were evacuated vertically, but due to the disruption of lifelines, it was difficult to get warm by themselves and transfer hospitals. On the other hand, 5% of victims that were in houses at the time of the earthquake were washed away, 40% were completely destroyed, and 15% were flooded above or below the floor. 8% had no housing damage.
