The common situational awareness among the disaster-response organizations and the appropriate action based on the information sharing are the key factor for the effective and efficient disaster response. Supported by the Cross-ministerial Strategic Innovation Promotion Program (SIP), we have developed the Shared Information Platform for Disaster Management (SIP4D) which facilitate the “cross-ministerial information sharing” by intermediating the various governmental organizations. Also, as the empirical research for utilize the shared disaster-information by SIP4D, we have developed the Medical Activity Support System for Disaster Management, the Reservoir Disaster Prevention Support System, and the Disaster Management Information Service Platform. In this paper, we introduce the overview of our R&D project, and report the implementation plans of our systems in the society.

In disaster response, wherein many organizations undertake activities simultaneously and in parallel, it is important to unify the overall recognition of the situation through information sharing. Furthermore, each organization must respond appropriately by utilizing this information. In this study, we developed the Shared Information Platform for Disaster Management (SIP4D), targeted at government offices, ministries, and agencies, to carry out information sharing by intermediating between various information systems. We also developed a prototype of the National Research Institute for Earth Science and Disaster Resilience (NIED) Crisis Response Site (NIED-CRS), which provides the obtained information on the web. We applied these systems to support disaster response efforts in the 2016 Kumamoto Earthquakes and other natural disasters. We analyzed the effects of and issues experienced with the information sharing systems. As effects, we found 1) the realization of increased overall efficiency, 2) validity of sharing alternative information, and 3) possibility of using the system as a basis for information integration. As future issues, we highlight the needs for 1) advance loading of data, 2) machine readability of top-down data, and 3) identifying the common minimum required items and standardization of bottom-top data.

Concept Of Information

The purpose of this paper is to consider the essential concept by which to formulate standardized information that supports effective disaster response. From the experiences of past disasters, we have learned that disaster response organizations could not work effectively without information sharing. In the context of disaster response, the purpose of “information sharing” is to ensure common recognition of the disaster situation being confronted. During the Kumamoto earthquake, we provided a set of disaster information products to disaster response organizations to support their relief activities. Based on the real disaster response experience, we extracted issues of information sharing between various organizations. To resolve these issues, we discuss the concept of information sharing first, and then consider the quality of information that supports disaster response activities by referring to the information needs of emergency support organizations such as the Disaster Medical Assistance Team (DMAT). We also analyze the Basic Disaster Management Plan published by the Central Disaster Management Council and extract a common disaster-information set for governmental organizations. As a result, we define the “Standard Disaster-information Set” (SDS) that covers most disaster response information needs. Based on the SDS, we formulate intermediate information products for disaster response that provide consistent information of best-effort quality, named the “Standardized Disaster-information Products” (SDIP). By utilizing the SDIP, disaster response organizations are able to consolidate the common recognition of disaster situations without consideration of data availability, update timing, reliability, and so on.

For the purpose of realizing horizontal information sharing among organizations involved in disaster management in the Tokyo metropolitan area, this study aims to extract problems in responding to disaster in the initial stage of a Tokyo metropolitan near-field earthquake disaster, to develop applications for disaster management to contribute to solving these problems, and to implement a demonstration of the information linkage incorporating applications for officials of local governments in charge of disaster management and fire-fighting. To put it concretely, Kanagawa Prefecture, Yokohama City, and Kawasaki City were selected as the area for demonstration, and simultaneous multiple fires and emergency medical transport by helicopter and ambulance were taken up as the main subjects of the demonstration. The demonstration was implemented for application to disaster management consisting of fire spread simulation, an information-sharing network for disaster relief helicopters, a system for emergency medical transport by ambulance, a system for disaster response management and an all-purpose disaster information viewer, and information linkage incorporating an information-sharing database.

2016 Kumamoto Earthquakes

In order to efficiently gather and effectively utilize information fragments collected in the initial stage of disaster response, those who utilize shared information need to determinate which information to gather and conduct appropriate processing as necessary. On the occasion of the 2016 Kumamoto earthquakes, the National Research Institute for Earth Science and Disaster Resilience (NIED) sent a resident researcher to the Kumamoto Prefectural Office the following day to implement disaster information support that included organizing various pieces of disaster information collected via telephone, fax, and the like on a WebGIS to generate an information map that was then provided to bodies that carry out disaster response. In light of this series of disaster information support activities, this article analyzes the necessary requirements for utilizing disaster information at a disaster response site; in other words, it addresses a problem with the effective utilization of a large amount of shared information in conducting disaster response activities. As a result, an outline of the information items that are necessary for utilization of disaster information has become clear. This provides a suggestion for the conception of a system for each disaster response body to utilize disaster information for carrying out activities at the disaster site.

Dirichlet Allocation

Natural disasters cause significant damage, casualties and economical losses. Twitter has been used to support prompt disaster response and management because people tend to communicate and spread information on public social media platforms during disaster events. To retrieve real-time situational awareness (SA) information from tweets, the most effective way to mine text is using natural language processing (NLP). Among the advanced NLP models, the supervised approach can classify tweets into different categories to gain insight and leverage useful SA information from social media data. However, high-performing supervised models require domain knowledge to specify categories and involve costly labelling tasks. This research proposes a guided latent Dirichlet allocation (LDA) workflow to investigate temporal latent topics from tweets during a recent disaster event, the 2020 Hurricane Laura. With integration of prior knowledge, a coherence model, LDA topics visualisation and validation from official reports, our guided approach reveals that most tweets contain several latent topics during the 10-day period of Hurricane Laura. This result indicates that state-of-the-art supervised models have not fully utilised tweet information because they only assign each tweet a single label. In contrast, our model can not only identify emerging topics during different disaster events but also provides multilabel references to the classification schema. In addition, our results can help to quickly identify and extract SA information to responders, stakeholders and the general public so that they can adopt timely responsive strategies and wisely allocate resource during Hurricane events.

Purpose – Trust in disaster communication is significant because a lack of trust will prevent the transformation of information into usable knowledge for an effective disaster response. Therefore, the purpose of this paper is to investigate how the culture and network ties of an affected community can encourage trust and participation in disaster communication. Design/methodology/approach – A qualitative case study of Jalin Merapi (JM) was conducted by interviewing 33 research participants in the Mt Merapi surroundings. Findings – The findings indicate that culture-embedded disaster communication plays important roles in increasing the effectiveness of disaster information and encouraging trust in the authenticity of locally based disaster information at the individual level. The findings also identify that strong ties and weak ties play different roles in disaster communication. The strong ties are more effective in facilitating information diffusion and encourage trust and community participation within the affected community. Furthermore, the weak ties are more effective in disseminating information to wider audiences, and have an indirect influence in encouraging trust by extending the offline social network owned by the affected community. Originality/value – Most literature on disaster communication focusses on the construction of disaster messages to encourage effective disaster response. Less attention has been paid to the information receivers regarding how disaster information is considered to be trustworthy by the affected community and how it can increase collective participation in community-based disaster communication.
