    The Pohang earthquake(M5.4) that occurred on 15th November 2017 is the first earthquake that operated earthquake evacuation shelters in South Korea. In order to present the future direction of disaster prevention measures, this survey was conducted with emphasis on the operation condition of the evacuation shelters in the Pohang earthquake.

    In conclusion, there were many responses by public-private cooperation. For example, up to 40% of evacuees are accepted in private facilities such as churches. And civil society organizations conducted emergency safety inspections, and companies provided material support. Compared with the Gyeongju earthquake in 2016, the disaster response of the government was improved, but there are problems such as the absence of earthquake evacuation shelters operation manuals.

    In the earthquake that occurred in Kumamoto prefecture and Oita prefecture on April 14, 2016, the push type emergency logistic transportation was carried out for emergency materials transportation during responses of initial stages.

    This research analyzes the responses for the push type emergency logistic transportation during the 2016 Kumamoto earthquake disaster. Based on this result, the activate requirements for the push type emergency logistic transportation. The requirements are needed to be prepared for the effective initial operation for the emergency logistics for next big disasters.

    The table of contents and its structure of local disaster management plan are not unified in Japan, which cause inefficient mutual assistance between local governments during disaster response. This paper makes comparisons the table contents of local disaster management plan between local governments in Kumamoto prefecture to clarify the difference and issues. Based on the comparison result, structure and number of chapter between local governments differ greatly, which may cause inefficiency during disaster response. In addition, this paper points out situation that some of the important contents are not included in the plan of some local governments.

    In this paper, we proposed the emergency logistic transportation for effective operations in terms of emergency logistics. The proposal is used the combination of the set bag of delivered goods and the transportation method using containers. As a result, by preparing evacuator set bags in advance, sorting is unnecessary, it is unnecessary to carry heavy cardboard boxes, and special skills and equipment are also unnecessary. Regarding the transportation of emergency materials, the public assistance such as voluntary disaster prevention organizations and fire brigades can be utilized for the emergency logistics transportation. And as the result of calculating the number of containers for the number of refugees in the 2016 Kumamoto earthquake disaster, it showed that it was able to cover the supplies with containers set in Kumamoto prefecture.

    Local Disaster Management Plan formulates what local government is supposed to do before and after disaster. This plan is basic document for local government but is not utilized properly during disaster response due to its large volume and low searchability. Based on this background, this paper visualizes the contents of the plan and summarizes it as Disaster Response Flow. In addition, detail information necessary for implementing each contents of the plan are collected from affected local governments in the Kumamoto Earthquake and its database was developed. Finally, this paper visualizes relationship between departments on disaster response as network flow.

    In the past disaster response, inefficient disaster response occurred at local government due to lack of human resource management, which led to delay of recovery and reconstruction. This is because no method to evaluate and simulate quantitatively about work volume of disaster response and current human resource capacity of local government. Based on this background, authors' group conducted questionnaire survey to affected local governments during Kumamoto Earthquake in 2016. This questionnaire collected the data about work volume of each disaster response work in time series after the earthquake occurred. By making comparison this work volume and damage value, prediction formula to calculate necessary human input volume from disaster damage was developed.

    Earthquake wave amplification at a particular site, due to local soil conditions, causes severe damage to infrastructures, including both ground structures and buildings. In conventional design practices wherein a generalised design response spectrum is used, it is difficult to efficiently capture the frequency characteristics of the local site condition and the characteristics of past earthquakes at that particular location. In order to achieve this goal real earthquake ground records are required. A vital component of this research was to develop a ground motion database through measurement sensors placed at different depths of ground at various locations in the Tokyo Metro region. The observations began in the year 1976 with periodic change of type of sensors in the process in the advent of expiry and improvement in the technology. The digital records of the data are available since1999 at three locations. The observed data is converted to its binary format with the appropriate calibration suitable for the sensors. Further, corrections and filters have been applied to rectify the data. In addition to this large database, a comprehensive list of metadata characterising the source of the earthquake from the Japan Meteorological Agency (JMA) is compiled.
