Blood supply during Japan's 1995 Hanshin-Awaji Earthquake.

On January 17, 1995, a magnitude 7.3 earthquake occurred in southern Hyogo Prefecture, a substantially urban area of Japan's main island, Honshu. Now known as the Hanshin-Awaji Earthquake, this disaster damaged or destroyed 639 686 houses and took 6434 lives. Within the disaster area, the Japanese Red Cross (JRC) Hyogo Blood Center had regional responsibilities for collecting, testing, processing, storing, and distributing blood components, including red blood cells (RBCs), fresh frozen plasma (FFP) and platelet concentrates (PLTs). Platelet shakers collapsed, forcing the discard of 103 PLT bags (1125 units) that could not be temperature-controlled or agitated. RBCs and FFP in refrigerated and frozen storage, respectively, remained in temperature control with the help of dry ice imported from non-affected areas. Local blood collection was suspended and replaced by products from other blood centers. Local demand for blood components decreased to 66% of comparable pre-quake demand. Emergent supplies rather than reserved supplies of blood components were markedly increased after the earthquake. Communication infrastructure damage prompted JRC Hyogo Blood Center to send blood delivery vehicles loaded with RBCs and FFP on a circuit of main hospitals in the affected area. Local blood donation and processing resumed 20 days after the quake. In retrospect, a nationally coordinated system of production and distribution demonstrated JRC's ability to meet transfusion demand after the 1995 Hanshin-Awaji Earthquake, and prompted changes in anticipation of subsequent disasters.
