This deliverable presents the results of our analysis the use of Social Media before, during and after emergencies. It is based on a comprehensive study of the Social Media related behavior of authorities (among EMS) and the general public in past emergencies.

Purpose of the Document

The aim of this document is as follows:

  • Identify and map several types of users, in terms of motivation, attitudes and behavior of both authorities and the public, based on past emergencies and a stakeholder analysis.
  • Provide an accompanying analysis of the current use of Social Media based on different role patterns both from the citizen and the authorities perspective and both from the producer and consumer perspective (information provider and/or information dissemination), which lead to use cases of Social Media in emergencies.

In order to achieve this purpose the following tasks have been performed:

  • We have reviewed related work on Social Media in emergencies in order to identify usage patterns as well as role patterns (section 2).
  • Furthermore we have reviewed related work on data quality problem patterns in emergencies (section 3).
  • A third review summarized related research projects (section 4).
  • Based on these foundations we will present the results of our interview study, which has been conducted in 7 European countries and 8 different cities and provided insights in current use of Social Media, which is sometimes not covered in research (section 5). Finally we will summarize our findings.
