Perspective of “Management by Objectives” is important for local government which has to manage seismic disaster strategically. But there was no specific way of how to set objectives. In order to realize Management by Objectives, it is necessary to make an effective incident action planning which is equivalent to objectives before disaster. In order to make an effective incident action planning, it is necessary to balance three elements, schedule, resource, and scope. The framework of Project Management represented by PMBOK is effective to balance these three elements. Although the step “make a network diagram and find a critical path” exists in the technique of Project Management, a network diagram about seismic disaster management by local government does not exist until now. As a consequence, it is impossible to progress to the following steps about making an incident action planning.

This research carries out a case study based on actual result of the 1995 great Hanshin-Awaji earthquake disaster management, and makes a prototype network diagramof seismic disaster management by using “Program Evaluation and Review Technique (PERT)”. This network diagram makes it possible to conducts critical path analysis. As a consequence, one of conditions to make an effective incident action planning is right.

This paper focuses on the transmission characteristics of evacuation information at the time of disaster. The transmission characteristics is defined in terms of the three properties; fastness, rightness and sureness in this study. Influence of transmission tools on the transmission characteristics in evacuation information announcement was examined based on the evacuation information transmission test conducted in Mitsuke City, Niigata Prefecture. Six different transmission tools were used in the test. Questionnaire investigation to citizen of Mitsuke City was conducted. Four investigation tools were evaluated using the three properties. As a result, the area mail, notification sent to persons in a specific area, was evaluated as the fastest and the rightest tool. In addition, the investigation indicated that the combination of different information tools is more than extremely effective.

The purpose of this study is to provide higher estimation of heavy rain scale in Japan by our proposed method. An installation of an observation points is insufficient for the estimation. Therefore, due to this insufficiency, we used the observation values of a monitoring point as a substitute for the values of different areas. However, the values have a discrepancy between their observation point and the location of the actual damage. The calculation of the risk indices requires a time interval; thus, there is a discrepancy between the temporal resolution and the actual timing at which the damage occurred. This study proposes an indicator model that provides estimation of heavy rain scale. The estimated values and indicators were implemented and evaluated by using our indicator model. The indicators correlated significantly well with the actual rainfall in comparison to the observation values. The proposed indicator model results that the indicators may estimate heavy rain with high immediacy when considering the purpose of monitoring disaster damage.

In this paper, we considered the general peoples' opinions toward the impossibility of the earthquake prediction. It may be laid down as a public feeling that most of people desire that somebody, such as some competent administrative body, declare how big, when and where the next great earthquake will occur. On the other hand, the Cabinet Office proposed the view that the earthquake prediction is impossible at this point in time, in May 2012. It is clear that the above government's official view is exactly the opposite of the above public feeling. Therefore, it is supposed that many people will show a negative reaction to the above government's official view, and that the risk communication regarding with the earthquake prediction between the public and the government broke down.

As a result of the verification by using a questionnaire survey, we received valuable suggestions that the above public feeling may be one of the causes for the negative reaction to the above government's official view.

This paper examines that discussion expand and cultivate knowledge structure around disaster mitigation. One of a problem about disaster education is that residents are hard to take action for disaster mitigation in spite of knowledge they have. We think a reason of it that resident's knowledge isolated each other and need to construct knowledge structure to do disaster mitigation action.

We did an experimentation to examine it. A test held on Facebook as Social Network Service (SNS) to solve a problem of disaster education which is physical limitations. An experimentation procedure is as follows. First, the subjects watch the animation about Tokyo earthquake and diagnosis the risk of their daily milieu on a web application which is supplied by experimenters. Second, they draw the predicted situation of Tokyo earthquake with reference to the animation and a web application. Finally, they share and discuss opinions about predicted situation of the Tokyo earthquake with others.

After a test, author analyzed it by four analyses, raw frequency analysis, content analysis with grounded theory approach, co-occurrence network analysis, collocation analysis. The analyzed result shows that knowledge structure around disaster mitigation of subjects expanded and cultivated through an experimentation.

The result shows that discussion around disaster mitigation through SNS has a possibility to expand and cultivate knowledge structure on disaster education.

In this paper, on the basis of introspection that the information of the earthquake early warning has not been communicated well at the time of the Great East Japan Earthquake, we have proposed how to broadcast the earthquake early warning automatically and then developed the automatic broadcast equipment by using the proposed method and implemented these equipments to some existing broadcast devices in our campus. We will report the result of the operation and improvements of this equipment for several years.

Currently, the earthquake early warning that the Japan Meteorological Agency has been announced is a feature that the revised information is issued in many times against one earthquake. Even after the alert was issued once, revised information was issued successively. Among this successive revised information, some important information was included such as that the epicenter information was corrected from the alert issued or that the earthquake magnitude became huge gradually and became giant earthquake than when the alert was issued.

We have proposed two broadcast control matrix of the estimated seismic intensity and estimated magnitude as a specific method that can be automatically determines the important information from subsequent information, and re-broadcast properly. In addition, as broadcast start conditions, we have proposed two broadcast start conditions that the one is in the earthquake usually occurs and the other is when the giant earthquake occurred. And we have developed the automatic broadcast equipment of the earthquake early warning that was implemented the method proposed, and connected to the existing broadcast facility on campus, and operated during about two and a half years. Until now, we have been improving the equipment while operation. However, only the receiving side of the earthquake early warning, it was also found that there is a limit to improve the problem.
