Social media is increasingly being used during emergencies. Most available studies are focused on how citizens and/or authorities use these technologies in concrete events. However, larger quantitative studies with significant results on attitudes, needs and future plans of citizens in such events are not available - especially such of a comparative nature related to emergency services. As part of the EU project ‘EmerGent’ this article presents the findings of a survey of 1034 citizens across 30 European countries conducted between February and June 2015 to explore citizens' attitudes towards the use of social media for private purposes and in emergency situations. The article briefly compares these findings with a second survey conducted with 761 emergency service staff across 32 European countries from September to December 2014. The aim of the overall study is to discuss citizens' attitudes towards social media in emergencies in order to derive challenges and opportunities for social resilience.

Various studies show that social media is used in emergencies - and that in spite of possible challenges for emergency services, beneficial use cases can be identified. However, relatively little empirical data is available regarding the attitudes of emergency services towards social media, and almost none of a comparative nature. This article summarizes the findings of a survey conducted of the EU project 'EmerGent' with 761 emergency service staff across 32 European countries from September to December 2014. The main aims of the survey were to explore the attitudes expressed by emergency service staff towards social media for private and organizational use as well as the levels and main factors influencing the current and likely future use of social media in their organizations. Based on our results, we discuss possible enhancements of the emergency management cycle using social media. We did a survey with 761 emergency service staff across 32 European countries.The majority of emergency services has positive attitudes towards social media.It is more used to share information (44%) than to receive messages (19%).A future increase is expected (74%), even more for organizations already using it.There is a huge gap between rhetoric (66%) and reality (23%) in social media use.

Finding a way to ensure an effective use of social media has become increasingly important to emergency services over the past decade. Despite all efforts to determine the utility of social media for emergency organisations, it is necessary to benefit from such institutions' staffs’ opinions to establish effective use. To provide empirical evidence we present a comparison of two surveys, conducted across Europe with emergency services in 2014 and 2017 respectively, with a total of 1169 answers. The analysis shows that personal experience has an effect on how organisational usage of social media is perceived and how emergency service staff view the future use of social media. Furthermore, the use has increased. This article not only shows emergency services what their staff think about their social media usage but also discusses challenges and future directions for the design of systems that can be useful for further development of optimized organisational social media usage.

During a large-scale crisis, many people use social media to share information. However, emergency services are unable to use this information easily due to data quality and quantity issues. We use Twitter data generated during a recent flooding crisis to gain insights into this problem, evaluating techniques that could be used in real-time to provide actionable intelligence to emergency services. Our work also includes an exploratory analytical study of the data.
