Mobile applications in crisis informatics literature: A systematic review

How members of society interact during disasters has significantly changed because of technological innovations and new media evolution. The modality changes in crisis communications, such as the popular rise of mobile applications use, may pose risks to the public if not properly studied, with results adopted and utilised. Crisis informatics, as an emerging field of research, studies the socio-technical advancements in disaster management. The purpose of this review is to summarise the involvement of mobile applications (apps) in crisis informatics literature and to scope needs and opportunities for further research on citizen's use of mobile apps during disasters.This review uses a scoping process to identify and analyse 49 crisis informatics articles that focus on mobile apps in disaster situations. The study investigates the various mobile apps that engage with the crowd during disaster situations. Findings show that apps used in disasters can be general-purpose apps or built-for-disaster-purpose apps. This review further focuses on the built-for-disaster-purpose apps and shows the various interactions these apps foster with the public and the apps' value-added contributions throughout the disaster life cycle.Communication during disasters between the public and authorities has become more dispersed. To fully augment disaster resilience through technology it is important that future research should engage in user-centred studies to gain more insights from the citizens' on using mobile apps. This study highlights three areas of need for future research: engagement of apps prior disaster response stage, public behaviour and motivation towards the use of apps, and usability of mobile apps.
