Subsurface technologies, such as geothermal energy and carbon capture and storage, are options to help limit global warming. Subsurface technologies involve the risk of induced seismicity. The successful implementation of these technologies depends on the public perception of these risks. Risk governance frameworks propose assessing the level of public concern and designing adapted risk mitigation measures. We propose that concerns should not only be investigated with respect to the perceived risks but also with respect to the potential mitigation measures. We explore this by analyzing the perception of risk mitigation measures for different subsurface technologies. With an online survey (N = 808) in Switzerland we analyzed four technologies (in-between subject design) and four mitigation measures (within subject design). We found that risk mitigation measures are perceived differently, within and across technologies. Thus, public concerns about risk mitigation really matter. We suggest that future research should focus on how risk mitigation measures can be applied and communicated to realize the full potential of risk governance frameworks.

地下技术，例如地热能以及碳捕获和存储，是有助于限制全球变暖的选择。地下技术涉及诱发地震的风险。这些技术的成功实施取决于公众对这些风险的认识。风险治理框架建议评估公众关注的程度并设计适当的风险缓解措施。我们建议，不仅应就感知到的风险进行调查，而且还应就潜在的缓解措施进行调查。我们通过分析针对不同地下技术的风险缓解措施的看法来探索这一点。通过在线调查（否 = 808），我们在瑞士分析了四种技术（在主题设计之间）和四种缓解措施（在主题设计之内）。我们发现，在技术内部和技术之间，对缓解风险的措施的看法不同。因此，公众对降低风险的担忧确实很重要。我们建议未来的研究应集中在如何应用和传达风险缓解措施以实现风险治理框架的全部潜力。
