Abstract
Purpose
The aim of this study is to investigate how social media users' experience of seeking emergency information affects their engagement intention toward emergency information with a reciprocity framework integrated with information adoption model.
Design/methodology/approach
Drawing on reciprocity theory, indebtedness theory, and information adoption model, an integrative research model is developed. This study employs a questionnaire survey to collect data of 325 social media users in China. Structural equation modeling analyses are conducted to test the proposed theoretical model.
Findings
Social media users' experience of seeking emergency information has a strong effect on their perceived information usefulness and indebtedness, while perceived information usefulness further influences community norm, indebtedness, and engagement intention. The authors also found that perceived information usefulness mediates the relationships between experience of seeking emergency information and community norm/indebtedness.
Originality/value
This study offers a new perspective to explain social media users' engagement intention in the diffusion of emergency information. This study contributes to the literature by extending the theoretical framework of reciprocity and applying it to the context of emergency information diffusion. The findings of this study could benefit the practitioners who wish to leverage social media tools for emergency response purposes.

Abstract
Purpose
The aim of this study is to develop and redesign the Mobile Panic Button UI (PB1) application as an emergency notification service, as well as conduct a simulation on the use of the new version of the application.
Design/methodology/approach
This study used the operational research design with a theoretical research framework that followed input, process and output. Primary data were collected through observation, measurement and interview while the secondary data were obtained from literature review. The first step of the analysis was input analysis that included problem identification on the existing Panic Button as input, or PB 1 in this study. This was followed by the analysis of the planned second version of the Panic Button (PB2) development, starting from problem identification to trial and error testing and evaluation of the results of the simulation of seven types of emergency events that involved users, emergency response officers and experts.
Findings
The study shows that the first version of PB1, developed in and used since 2017 at Universitas Indonesia, still had several weaknesses, particularly in its inability to provide adequate information. Only 30% of the standards for a mobile emergency application were met by PB1, which affected the performance of emergency responses. This was one of the reasons why the new version of Panic Button UI (PB2) was developed. The new features in PB2 comprise the inclusion of features for collecting information on user's name and mobile phone number, emergency category options, victim information, photo/voice information, description on the nature of the emergency (text), location selection, emergency notification delivery, notification delivery popup and emergency notification delivery to the emergency response team (ERT) officer. The time needed for using the second version of the Panic Button UI mobile application is 20 s faster than the previous one. PB2 can accelerate response time and response action time; improve response accuracy; facilitate the emergency notification process; and facilitate emergency communication.
Originality/value
Various notification alert systems have been developed in many countries. However, there is a lack of information in Indonesia, especially in educational setting. This study is the first study on a notification alert system application applied in the university. Emergency response is critical due to the big impact of disasters. This study will inform the stakeholders or users, particularly those in educational institution on how to implement mobile app–based emergency response notification systems.

Abstract
Purpose
This study aimed to analyze existing problems in the dissemination and management of emergency information on social media platforms, improve social media users' experience regarding such information, increase the efficiency of emergency information dissemination and curb the spread of misinformation.
Design/methodology/approach
In this study, the emergency information quality on social media platforms was examined. Based on the evaluation principles of the quality of mature information, social media information characteristics and the rules of emergency information dissemination, combined with relevant academic research results, an index to evaluate the quality of emergency information on social media was constructed. In addition, the authors have introduced cloud theory as an information quality evaluation method and used social media users' emotional characteristics to assess information quality evaluation results. A comprehensive system for evaluating emergency information quality, including indexes, methods and detection strategies was established. Based on a comprehensive system, a case study was conducted on the forest fires in Sichuan Province and the African swine fever events as reported on the Zhihu platform. In accordance with the results of the case study, the authors expanded the research and introduced the emotional characteristics of social media users as an independent evaluation dimension to evaluate the quality of emergency information on social media.
Findings
The comprehensive system's effectiveness was verified through the case study. Further, it was found that users' emotional characteristics (reflected in their information behavior) are inconsistent with their evaluation of websites' information quality regarding major emergencies. Integrating users' emotional characteristics into the information evaluation system can enhance its effectiveness following major emergencies.
Originality/value
First, an evaluation index system of emergency information quality on social media about major emergencies was offered. Unlike the commonly available index system for information quality evaluation, this proposed evaluation index system not only accounted for the characteristics of social media, such as massive disordered information, multiple information sources and rapid dissemination, but also for the characteristics of emergency events, such as variability and the absence of precursors. This proposed evaluation index system enhances the pertinence of the information quality evaluation and compensates for the shortcoming that the current research only focuses on evaluating social media information quality in a broad context, but pays insufficient attention to major emergencies. Second, cloud theory was introduced as a method to evaluate the emergency information quality found on social media. Existing research has primarily included the use of traditional statistical methods, which cannot transform numerical values into qualitative concepts effectively. Various indeterminate factors inevitably affect the quality of emergency information on social media platforms, and the traditional methods cannot eliminate this uncertainty in the evaluation process. The method to assess emergency information quality based on cloud theory can effectively compensate for the gaps in the research and improve the accuracy of information quality assessment. Third, the inspection and the dynamic adjustment of assessment results are absent in the research on information quality assessment, and the research has relied principally on the information users' evaluation and has paid insufficient attention to their attitudes and behaviors toward information. Therefore, the authors incorporated users' emotional characteristics into the evaluation of emergency information quality on social media and used them to test the evaluation results so that the results of the information quality assessment not only include the users' explicit attitudes but also their implicit attitudes. This enhances the effectiveness of the information quality assessment system. Finally, through this case study, it was found that an inconsistency exists between user evaluation and user emotional characteristics after major emergencies. The reasons for this phenomenon were explained, and the necessity of integrating user emotional characteristics into information quality assessment was demonstrated. Based on this, the users' emotional characteristics were used as a separate evaluation dimension for assessing the quality of emergency information on social media. Compared with assessing the quality of general information, integrating the user's emotional characteristics into the evaluation index system can lead the evaluation results to include not only the users' cognitive evaluation but also their emotional experience, further enhancing their adaptability.

Abstract
Purpose
The purpose of this paper is to explore themes eventuating from the user-generated content posted by users on the Facebook page of an emergency management agency.
Design/methodology/approach
An information classification framework was used to classify user-generated content posted by users including all of the content posted during a six month period (January to June 2015). The posts were read and analysed thematically to determine the overarching themes evident across the entire collection of user posts.
Findings
The results of the analysis demonstrate that the key themes that eventuate from the user-generated content posted are “Self-preparedness”, “Emergency signalling solutions”, “Unsurpassable companion”, “Aftermath of an emergency”, and “Gratitude towards emergency management staff”. Major user-generated content identified among these themes are status-update, criticism, recommendation, and request.
Research limitations/implications
This study contributes to theory on the development of key themes from user-generated content posted by users on a public social networking site. An analysis of user-generated content identified in this study implies that, Facebook is primarily used for information dissemination, coordination and collaboration, and information seeking in the context of emergency management. Users may gain the benefits of identity construction and social provisions, whereas social conflict is a potential detrimental implication. Other user costs include lack of social support by stakeholders, investment in social infrastructure and additional work force required to alleviate the technological, organisational, and social barriers in communication among stakeholders in emergency management. A collective activity system built upon the Activity Theory was used as a lens to describe users’ activity of posting content on the Facebook page of an emergency management agency.
Practical implications
By analysing the findings, administrators and policy makers of emergency management could identify the extent to which the core principles of disaster recovery are accomplished using public social networking sites. These are achieved in relation to: pre-disaster recovery planning; partnership and inclusiveness; public information messaging; unity of effort; and, psychological recovery to maximise the success of recovery in a disaster. Furthermore, a core principle which evoked a mixed response was timeliness and flexibility.
Originality/value
Previous studies have examined the role of social networking sites in disastrous situations, but to date there has been very little research into determining themes found in user-generated content posted on the Facebook page of an emergency management agency. Hence, this study addresses the gap in literature by conducting a thematic analysis of user-generated content posted on the Facebook page of the Federal Emergency Management Agency.

Abstract
Purpose
Most of the existing studies on the evolution of emergency topics in social media focused on the emergency information demand of fixed user type in emergency while ignoring the changing roles of stakeholders during the emergency. Thus in this study, a three-dimensional dynamic topic evolution model is proposed, in which fine grained division of time, dynamic identification of stakeholders in the emergency, and emergency topic evolution based on both timeline and stakeholder's type are all considered.
Design/methodology/approach
Particularly the relevance between the tweets posted and the topic of emergency, the influence on the social network, and the attention of emergency topic are as well taken into account to quantitatively calculate the weight and ranking of stakeholders at different stages of the emergency. To verify the proposed model, an experimental demonstration was carried out under an emergency event posted on social media.
Findings
The results show that (1) based on the three-dimensional dynamic topic evolution model, the composition and ranking of stakeholders have obvious differences at different stages; (2) the emergency information needs and the sharing behavior of stakeholders on emergency information also indicate different preferences where the topic concerns of stakeholders at different stages have a strong relationship with their weight ranking; (3) the emergency topic evolution considering both the dynamics of emergency stakeholders and emergency information demand could more accurately reflect the changing regularity of social media users' attention to information in emergency events.
Originality/value
This study is one of first to investigate the emergency topic evaluation on social media by considering the dynamic changes of various stakeholders in emergency. It could not only theoretically provide more accurate method to understand how users share and search emergency information in social media, but also practically signify an information recommendation way in social media for emergency tracking.

Abstract
Purpose
The purpose of this paper is to develop a multi-agent-based simulation model for the online opinion dissemination during hazardous chemical leakage emergencies into rivers in China, to explore an appropriate crisis information release policy of China’s government for controlling public panic.
Design/methodology/approach
In the proposed model, two fundamental attributes of crisis information, i.e., truthfulness (for true or false news) and attitude (for positive, neutral or negative opinion), are considered. Four major agents in the online community system, i.e., citizens, the government, media and opinion leaders, are included. Using four typical accidents of hazardous chemical leakage into rivers in China as case studies, insightful policy implications can be obtained for crisis management and panic control.
Findings
The news about the terrible potential damages from such a type of accidents will instantly arise wide-ranging public panic; therefore, the corresponding crisis information release policy should be carefully designed. It is strongly advised against publishing false news to temporarily conceal the accidents, which will seriously hurt the government’s reputation and agitate much larger-scale public panic in terms of degree and duration. To mitigate public panic, the true news especially about treatment measurements should be published immediately. If the government does nothing and releases no crisis information, the public panic will go out of control.
Research limitations/implications
This paper only focuses on the crisis information release policies from the perspectives of the government. Furthermore, this study especially focuses on the cases in China, and extending the proposed model study for general contexts is an important direction to improve this study. Finally, the proposed model should be extended to other types of emergencies to further justify its generalization and universality, especially various natural catastrophes like storms, floods, tsunamis, etc.
Originality/value
This paper develops a multi-agent-based model for online public opinion dissemination in emergency to explore an appropriate crisis information release policy for controlling public panic stemming from hazardous chemicals leakage accidents into rivers. The proposed model makes major contributions to the literature from two perspectives. First, the crisis information about emergency accidents are divided into true and false news based on the truthfulness attribute, and into neutral, positive and negative emotions based on the attitude attribute. Second, the proposed model covers the main agents in the online virtual community.

Abstract
Purpose
The purpose of this paper is to investigate how government affairs micro-blog (also referred to as GAM) are applied to the disclosure of government emergency information in China, to identify its existing problems and to provide solutions.
Design/methodology/approach
In this paper, online research, case analysis and other methods were used to analyze the application status of China’s Government micro-blog in emergency information disclosure in recent years. Based on the relevant data and cases, a systematic theoretical research is conducted according to the established research framework.
Findings
There are some problems in the application of GAM to crisis management, such as insufficient information dissemination, incomplete information disclosure, fragmentation of information and lack of dynamic updating and communication. So, it is necessary to strengthen the organization and management of GAM, establish a perfect emergency management mechanism of GAM, increase the positive influence of GAM on public opinions and establish an evaluation accountability system of administrative micro-blog management.
Originality/value
The analysis of the application of GAM to the disclosure of government emergency information and the proposed strategies for improving its performance are all original, and they are both meaningful to more effective usage of GAM and facilitation of government emergency information disclosure.

Abstract
Purpose
The purpose of this paper is to understand the effects of social media use on the resilience of organizations involved in emergency response. While social media has been utilized as a critical tool in the field of emergency management, few researchers have systemically examined its effect on organizations’ capacity to bounce back from catastrophic events. From the dimensional approach to social media use, this research focuses on the following three functions: providing information to local communities, transmitting information to local communities, and responding to the emotions of local communities.
Design/methodology/approach
The authors used survey data gleaned from 79 key organizations involved in emergency management to investigate the impact of social media use on resilience after a tragic flood in Seoul, South Korea in 2013. The authors also conducted interviews with ten emergency management officials to understand what administrative challenges they confront in using social media for their tasks.
Findings
The authors found that the provision of disaster information on social media such as Facebook, Twitter, and YouTube has a positive effect on the perceived level of organizational resilience. In addition, social media use correlates positively with community emotional responses.
Research limitations/implications
Given the focus on the emergency response to a natural disaster in urban areas, the results might not be generalizable to smaller cities or rural areas. The survey items that measure the perceptions of emergency managers may not represent the physical aspects of disaster recovery, such as the restoration of housing stock.
Practical implications
The findings suggest that public and nonprofit organizations can use social media to communicate with other organizations and the public in ways that demonstrate resilience. Emergency managers should address administrative challenges, such as trustworthiness of information delivered via social media and lack of personnel.
Originality/value
This paper provides systematic understandings of the effects of social media use on the resilience of the organizations that respond to a disaster.

Abstract
Purpose
Based on the perspective of knowledge management, this study aims to discuss how to build cross-city emergency management collaboration mechanism in major emergencies and explore the important role of knowledge management in emergency management collaboration.
Design/methodology/approach
Based on the theoretical analysis of knowledge management and the typical case study of cross-city emergency management collaborative rescue, this study provides an in-depth analysis of how these cities achieve high emergency management performance through multidimensional and multilevel knowledge collaboration, thus revealing the mechanism of knowledge transfer, integration and sharing in achieving high emergency management performance.
Findings
Through analyzing typical cases, this study finds that building a smooth mechanism for multichannel emergency rescue information can promote the diversification of knowledge transfer methods, building a platform-based integration mechanism for emergency rescue information can enhance knowledge integration capabilities and building a linkage mechanism for emergency rescue materials between cities can promote knowledge-sharing level, thereby improving emergency management performance level.
Research limitations/implications
This study has great significance for how to build cross-city emergency management collaboration mechanism in the digital era. In the future, the authors need to further discuss the following two aspects in depth: research on the impact of cross-city emergency management collaboration mechanism on improving the knowledge management capabilities of government emergency management departments; and research on the impact mechanism of knowledge management capabilities on city resilience.
Originality/value
Through case analysis of cross-city emergency management collaborative rescue for major emergencies in China in recent years, this study proposes three specific strategies for cross-city emergency management (smooth, integration and linkage mechanisms) and reveals that these three strategies are essentially aimed at improving the government’s knowledge management level.

Abstract
Purpose
The purpose of this study is to introduce the top-level design ideas and the overall architecture of earthquake early-warning system for high speed railways in China, which is based on P-wave earthquake early-warning and multiple ways of rapid treatment.
Design/methodology/approach
The paper describes the key technologies that are involved in the development of the system, such as P-wave identification and earthquake early-warning, multi-source seismic information fusion and earthquake emergency treatment technologies. The paper also presents the test results of the system, which show that it has complete functions and its major performance indicators meet the design requirements.
Findings
The study demonstrates that the high speed railways earthquake early-warning system serves as an important technical tool for high speed railways to cope with the threat of earthquake to the operation safety. The key technical indicators of the system have excellent performance: The first report time of the P-wave is less than three seconds. From the first arrival of P-wave to the beginning of train braking, the total delay of onboard emergency treatment is 3.63 seconds under 95% probability. The average total delay for power failures triggered by substations is 3.3 seconds.
Originality/value
The paper provides a valuable reference for the research and development of earthquake early-warning system for high speed railways in other countries and regions. It also contributes to the earthquake prevention and disaster reduction efforts.
