Due to the fact that social media that used ICT （information and communication technology） was useful in the days directly after the disaster, it can be said that it is necessary to investigate the provision of an information infrastructure that uses ICT to reduce the impact of disasters. Therefore, this study proposes the construction of a geographical information database using GIS and the provision and sharing of information using social media GIS after discussion of the relationship between the development of the computerization of Japan and GIS as a valid example of using information systems for recovery and reconstruction after the Great East Japan Earthquake.展开更多

Medical records and laboratory findings of the victims admitted in West China Hospital （WCH） were retro- spectively analyzed. Related data were compared between beforemath and aftermath of the earthquake and between WCH and frontier county hospitals. One thousand and thirty-one earthquake survivors were hospitalized, 1 358 victims underwent surgery and 142 victims were transferred to intensive care unit. The incidence of infection, crush syndrome and multiple organ dysfunction syndrome （MODS） was 39.6%, 20,7% and 2.3% respectively. Wound classification showed that the incidence of extremity damage was 72%, while the incidence of chest trauma, abdominal trauma and brain trauma was less than 10% respectively. Isolating rates of environmental pathogens were increased in the aftermath of earthquake, and the spectrum of the pathogens and related antibiotic sensitivities were quite different from those in the beforemath of earthquake. The social economic and population conditions in the earthquake-stricken areas affected the composition of the victims and the geographic features restricted the efficiency of rescue. Trauma-induced MODS, crush syndrome and severe infections all constituted the dilemma for the hospital care, to resolve whether the multidiscipline team work was proved to be an optimizing choice. For a more effective disaster protective response in the future, the study on rescue plan and the ladder therapies for massive casualties should be potentiated.展开更多

An alert protocol, intended as a working hypothesis, is proposed based on the experience gained from analysis of the behaviour and social response to the threat before and after the great disaster of the L’Aquila earthquake on 6th April 2009. Authors propose a protocol addressing four levels of increasing alert based on signs of earthquake preparation and social concerns. In this sense, it works as an intensity scale and does not strictly relate to earthquake size (magnitude) or seismic hazard. The proposed alert protocol provides sensible measures for reducing vulnerability, which is the only factor that can be more or less efficiently controlled, based on structural and behavioural adjustments. Factors indicating the difficult relationship between politicians, scientific community and citizens are considered: 1) a serious gap between researchers and citizens;2) measures adopted by local administrators and the National Civil Protection Service not agreed by the population;3) misunderstanding originated from a lack of clarity of communication about scientific terminology;and 4) the lack of an alert procedure protocol. In the current situation, all these problems are crucial and contribute to the unpreparedness to face a seismic event, and thus greatly increase the risk. The adoption and implementation of an alert procedure protocol requires a preliminary assessment of the context and should be adapted to the local sensibility and culture. The application of a protocol may reduce the contrasts between preventive measures and individual responsibilities, making mitigation measures more feasible and socially acceptable. In this paper, risk evaluation is not strictly related to probabilistic or deterministic predictions. In fact, this is a result of a project that comes from the general analysis of risk and is not intended to give an alternative hazard estimate method. This paper proposes an alert protocol addressing four levels of increasing alert based on signs of earthquake generating preparation and social concerns. Finally, there is a suggestion on how to gradually communicate the threat and get citizens involved in the risk mitigation process.展开更多

As part of AEIC activities, the SCMG implemented a project on the ASEAN Seismic Network for Rapid Exchange of Strong Earthquake Data (ASNET RESED). The project was implemented by the ASCMG with funding support from the Government of Japan through the Japan ASEAN Co-operation Promotion Program (JACPP). The aim of the project is to facilitate the rapid exchange of data and information on earthquakes with magnitudes greater than 5.5 on the Richter scale, and to link all of the ASEAN National Seismological Centers through the Internet to disseminate earthquake information. For the future program, we propose a seismic data exchange between the National Seismological Centers in ASEAN countries as well as world seismological centers using the facilities in the AEIC. The plan is basically to develop and update the software and hardware in the NSC and AEIC for data communication. To refresh our knowledge in seismology and data communication, we arrange the training sessions for both topics.展开更多
