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

Relief supply warehouses are material built to cope with natural disasters and guarantee the of life necessities. Great earthquakes (with Ms ≥ 7) overwhelming beyond human control. The efficiency in rescuing earthquake victims depends on if construction preparations large relief have fully assessed influence weights factors disasters. We innovatively proposes a method for selecting ideal site terms seismic evaluation quantification selection criteria. assess disaster-affected areas screen transport mode supplies based prediction remote sensing recognition, quantify classify criteria China, finally determine site. Taking seismically-active region as study case, we identify seven major areas, estimate largest safe flight range (255 km) helicopter post-earthquake supplies, pre-selecte 37 candidate sites. suggest that spatial distances between sites essential hubs (such airports, railway stations, highway entrances/exits) planning city crucial indicators selection.
