ABSTRACT

In many parts of Europe, heavy precipitation events are expected to increase in frequency and intensity. Since the current state of pluvial flood protection is low, there is a need to increase public risk perception and to encourage mitigation behavior. Doing this is the goal of risk communication, which is increasingly taking place via social media. In order to assess the importance/potential of social media for risk communication in relation to heavy precipitation events, this study aims to analyze the current status quo by time series-, network- and content analysis. The current risk communication fluctuates over time; therefore, a more continuous communication is required. Warnings, originating from established stakeholders were the most common type of messages; therefore, these stakeholders are especially important for risk communication. As there is a lack of information about protective measures and behavioral recommendations on social media, a more powerful dissemination of this information is needed.

摘要

在欧洲的许多地方，强降水事件的频率和强度预计会增加。由于当前洪水防护水平较低，因此需要提高公众风险意识并鼓励减灾行为。这样做是风险沟通的目标，它越来越多地通过社交媒体进行。为了评估社交媒体在与强降水事件相关的风险沟通中的重要性/潜力，本研究旨在通过时间序列、网络和内容分析来分析当前现状。当前的风险交流会随着时间的推移而波动；因此，需要更持续的沟通。来自既定利益相关者的警告是最常见的信息类型；因此，这些利益相关者对于风险沟通尤为重要。
