Triggered by technical progress that has allowed for the combining of information about natural, anthropogenic and socionatural hazards, numerous multi-hazard platforms have been established over the last years. Despite their increasing use, surprisingly, little research has been conducted evaluating how the public perceives of the hazard information provided by these multi-hazard platforms. Because most of them use maps on the start page, we were especially interested in the different approaches towards presenting multiple hazards and towards compiling the contents of the hazard announcements attached to the maps. With an online conjoint choice experiment (N = 768, fully randomised design), we tested different start page designs and hazard announcements representing the diversity of elements used in multi-hazard platforms. The alternatives were randomly displayed as pairs to the participants (between-subjects design), asking them to first rate the alternatives separately and then to choose which of the two they preferred. Our main results are that the participants prefer a start page consisting of a single map with textual information about the current hazards below the map. In addition, they prefer hazard classifications with four or five hazard categories. Moreover, the participants appreciate the embedding of a sharing function in the hazard announcements. Finally, the participants prefer a combination of textual and pictured behavioural recommendations. To conclude, the results indicate that the design of information provided on multi-hazard platforms indeed affects the public's preferences. Therefore, in parallel to the continuous improvement of scientific-technical products, the communication and perception of these products should be systematically examined too.

在技​​术进步的推动下，允许将有关自然，人为和社会自然灾害的信息结合起来，在过去几年中建立了许多多灾种平台。尽管越来越多地使用它们，但令人惊讶的是，很少进行研究来评估公众如何看待这些多危害平台提供的危害信息。因为它们中的大多数人都在起始页上使用地图，所以我们对呈现多种危险并编辑附在地图上的危险公告内容的不同方法特别感兴趣。通过在线联合选择实验（N = 768，完全随机设计），我们测试了不同的起始页设计和危害公告，这些危害代表了多危害平台中使用的元素的多样性。备选方案被成对地随机显示给参与者（受试者间设计），要求他们首先对备选方案进行单独评估，然后选择他们更喜欢的两种方案。我们的主要结果是，参与者更喜欢一个包含单个地图的起始页面，其中包含有关该地图下方当前危险的文字信息。此外，他们更喜欢具有四个或五个危害类别的危害分类。此外，与会人员对在危险公告中嵌入共享功能表示赞赏。最后，参与者更喜欢结合文字和图片中的行为建议。总之，结果表明，在多灾种平台上提供的信息设计确实会影响公众的偏好。因此，
