Abstract

Abstract. Probabilistic seismic hazard estimates are a key ingredient of earthquake risk mitigation strategies and are often communicated through seismic hazard maps. Though the literature suggests that visual design properties are key for effective communication using such maps, guidelines on how to optimally design hazard maps are missing from the literature. Current maps use color palettes and data classification schemes which have well-documented limitations that may inadvertently miscommunicate seismic hazard. We surveyed the literature on color and classification schemes to identify design criteria that have empirical support for communicating hazard information. These criteria were then applied to redesign the seismic hazard map for Germany. We established several communication goals for this map, including essential properties about moderate-hazard seismic regions and a critical hazard threshold related to the German seismic building codes. We elucidate our redesign process and the selection of new colors and classification schemes that satisfy the evidence-based criteria. In a mixed-methods survey, we evaluate the original and redesigned seismic hazard maps, finding that the redesign satisfies all the communication goals and improves users’ awareness about the spatial spread of seismic hazard relative to the original. We consider practical implications for the design of hazard maps across the natural hazards.

基于标准的危险地图可视化设计
摘要概率地震灾害估计是地震风险缓解策略的一个关键组成部分,通常通过地震灾害地图进行沟通。尽管文献表明,视觉设计特性是使用此类地图进行有效沟通的关键,但文献中缺少关于如何优化设计危险地图的指南。目前的地图使用调色板和数据分类方案,这些方案有充分的限制,可能会无意中错误地传达地震灾害。我们调查了有关颜色和分类方案的文献,以确定对传达危险信息具有经验支持的设计标准。然后,这些标准被应用于重新设计德国的地震危险地图。我们为这张地图制定了几个沟通目标,包括中等危险地震区的基本属性和与德国抗震建筑规范相关的临界危险阈值。我们阐明了我们的重新设计过程以及满足循证标准的新颜色和分类方案的选择。在一项混合方法调查中,我们对原始和重新设计的地震灾害地图进行了评估,发现重新设计满足了所有沟通目标,并提高了用户对地震灾害相对于原始的空间分布的认识。我们考虑了自然灾害危险地图设计的实际意义。

期刊介绍: Natural Hazards and Earth System Sciences (NHESS) is an interdisciplinary and international journal dedicated to the public discussion and open-access publication of high-quality studies and original research on natural hazards and their consequences. Embracing a holistic Earth system science approach, NHESS serves a wide and diverse community of research scientists, practitioners, and decision makers concerned with detection of natural hazards, monitoring and modelling, vulnerability and risk assessment, and the design and implementation of mitigation and adaptation strategies, including economical, societal, and educational aspects.
