Method for site selection of relief supply warehouses in earthquakes with Ms ≥ 7—a case study of western Yunnan, China

Abstract

Relief supply warehouses provide necessities of life for victims in disaster relief. The science behind site selection for large relief supply warehouses determines whether victims in earthquakes with Ms ≥ 7 can receive timely and effective relief. This study proposed a method of site selection for relief supply warehouses based on the prediction of earthquake disasters and the quanti cation of site selection criteria. This method considered four factors, i.e., the prediction of earthquake-prone areas, the identi cation of building distribution, the mode of post-earthquake transport of relief supplies, and the construction standards of relief supply warehouses. Taking western Yunnan Province for a case study, this study rst identi ed seven disaster-affected areas, then determined the helicopter's most extensive safe ight range in post-earthquake transport of relief supplies. Next, it quanti ed and classi ed the site selection criteria of relief supply warehouses in China and selected the top ten candidate sites meeting the necessary conditions. Finally, it obtained the ideal site using reference conditions. IntroductionWhen earthquakes with Ms ≥ 7 occur in anthropic zones, they damage infrastructure (such as buildings, structures, equipment, facilities, and transport) to varying degrees, signi cantly impacting normal production and life. In the face of an earthquake with Ms ≥ 7 and the secondary disasters induced by it, e cient and rapid emergency rescue can effectively reduce casualties and losses (Baghaian et al., 2022). An adequate reserve of necessities of life constitutes an essential material basis for emergency rescue and a necessary condition of earthquake emergency relief. The reasonableness of reserve siting and capacity directly determine the effect of earthquake emergency relief (Benini et al., 2009). Earthquakes with Ms ≥ 7 are infrequent, but they constitute natural disasters that pose serious threats to human beings, mainly due to their strong destructive power and poor predictability. In dealing with Ms ≥ 7earthquakes, the site selection of relief supply warehouses can be challenging, as site selection, in this case, is subject to many factors, including the prediction of earthquake-prone areas, the identi cation of areas with casualties, the failure of adjacent relief supply warehouses, and the timeliness of the arrival of relief supplies.

Evaluation of the Knowledge and Awareness of Firefighters in Turkey in Disaster Risk Management

“…It was reported that during disaster response operations, first responders faced inadequate equipment supply [70]. In China, during the earthquake measuring 7.9 on the Richter scale, search and rescue operations were hampered due to limited equipment, and intervention teams were reported to have dug out survivors with their bare hands [71]. In Haiti, during the earthquake measuring 7.0 in 2010, the lack of appropriate vehicles and equipment hindered search and rescue operations [72].…”
