Objective:The aim of this study was to identify disaster medical operation improvements from the 2016 Kumamoto Earthquake (Kumamoto Prefecture, Japan) and to extract further lessons learned to prepare for future expected major earthquakes.Methods:The records of communications logs, chronological transitions of chain of command, and team registration logs for the Disaster Medical Assistant Team (DMAT), as well as other disaster medical relief teams, were evaluated.Results:A total of 466 DMAT teams and 2,071 DMAT team members were deployed to the Kumamoto area, and 1,894 disaster medical relief teams and 8,471 disaster medical relief team member deployments followed. The DMAT established a medical coordination command post at several key disaster hospitals to designate medical coverage areas. The DMAT evacuated over 1,400 patients from damaged hospitals, transported medical supplies to affected hospitals, and coordinated 14 doctor helicopters used for severe patient transport. To keep constant medical and public health operations, DMAT provided medical coordination management until the local medical coordination was on-track. Several logistic teams, which are highly trained on operation and management of medical coordination command, were dispatched to assist management operation. The DMAT also helped to establish Disaster Coordination and Management Council at the prefectural- and municipal-level, and also coordinated command control for public health operations. The DMAT could provide not only medical assistance at the acute phase of the disaster, but also could provide medical coordination for public health and welfare.Conclusion:During the 2016 Kumamoto Earthquake, needs of public health and welfare increased enormously due to the sudden evacuation of a large number of residents. To provide constant medical assistance at the disaster area, DMAT, logistic teams, and other disaster medical relief teams must operate constant coordination at the medical headquarter command. For future expected major earthquakes in Japan, it will be required to educate and secure high enough numbers of disaster medical assistance and health care personnel to provide continuous medical and public health care for the affected area residents.Kondo H, Koido Y, Kawashima Y, Kohayagawa Y, Misaki M, Takahashi A, Kondo Y, Chishima K, Toyokuni Y.

Geographical Scope

Serious damages to enterprises as well as residences and infrastructure resulted from the 2016 Kumamoto Earthquake. Important factories of the automobile, information technology, chemical, and other industries were located in the affected area. The nature of the damage was that there was significant damages to the building of enterprises located near the fault that caused the strong Earthquake. The geographical scope of damage to the enterprises was not very wide.The authors performed continuous research on the public announcements posted on the websites of the affected enterprises for several months, following up with news reports on damaged enterprises and on-site interviews. We found that a considerable number of enterprises supplied their products to their important customers from substitute sites to achieve their business continuity. On the other hand, many enterprises attained early on-the-spot recovery, which might be explained partly by the fact that recovery of essential utilities, particularly electricity and telecommunications, was relatively quick.The authors found many examples of effective utilization of the lessons learned from the Great East Japan Earthquake (GEJE). For example, some enterprises adopted the substitution strategy of business continuity management (BCM) that fulfills the responsibility to maintain supplies to the customers. Other enterprises that had experienced the GEJE avoided serious direct damage by having installed adequate earthquake countermeasures to their buildings and facilities.

Abstract The earthquake rupture termination mechanism and size of the ruptured area are crucial parameters for earthquake magnitude estimations and seismic hazard assessments. The 2016 Mw 7.0 Kumamoto Earthquake, central Kyushu, Japan, ruptured a 34-km-long area along previously recognized active faults, eastern part of the Futagawa fault zone and northernmost part of the Hinagu fault zone. Many researchers have suggested that a magma chamber under Aso Volcano terminated the eastward rupture. However, the termination mechanism of the southward rupture has remained unclear. Here, we conduct a local seismic tomographic inversion using a dense temporary seismic network to detail the seismic velocity structure around the southern termination of the rupture. The compressional-wave velocity (Vp) results and compressional- to shear-wave velocity (Vp/Vs) structure indicate several E–W- and ENE–WSW-trending zonal anomalies in the upper to middle crust. These zonal anomalies may reflect regional geological structures that follow the same trends as the Oita–Kumamoto Tectonic Line and Usuki–Yatsushiro Tectonic Line. While the 2016 Kumamoto Earthquake rupture mainly propagated through a low-Vp/Vs area (1.62–1.74) along the Hinagu fault zone, the southern termination of the earthquake at the focal depth of the mainshock is adjacent to a 3-km-diameter high-Vp/Vs body. There is a rapid 5-km step in the depth of the seismogenic layer across the E–W-trending velocity boundary between the low- and high-Vp/Vs areas that corresponds well with the Rokkoku Tectonic Line; this geological boundary is the likely cause of the dislocation of the seismogenic layer because it is intruded by serpentinite veins. A possible factor in the southern rupture termination of the 2016 Kumamoto Earthquake is the existence of a high-Vp/Vs body in the direction of southern rupture propagation. The provided details of this inhomogeneous barrier, which are inferred from the seismic velocity structures, may improve future seismic hazard assessments for a complex fault system composed of multiple segments.
