灾害性地名是一种灾害性亚文化，其目的是为了识别一个地点，同时提醒人们过去的灾难经历。预计它们将传播高风险、低频率自然灾害的风险和知识，并在时间和世代中幸存下来。本文比较了日本三陆海岸具有真实和夸张起源的当地社区对海啸起源地名的看法。首先，通过使用地理信息系统和数字高程模型，将海啸起源的地名与2011年日本东部大地震中的海啸抬高进行比较，评估了海啸起源地名的真实性。相当大比例的地名都夸大了起源，但对当地社区的小组采访显示，人们更相信表明海啸不现实的起源，而不是更现实的起源。我们讨论，如果准确的危险信息与人们的日常生活和对安全的渴望相矛盾，它将被怀疑，即使不准确和模棱两可的信息如果嵌入到一个持续解释当地各种事实的当地知识体系中，也可以生存下来。
Disaster-originated placename is a kind of disaster subculture that is used for a practical purpose of identifying a location while reminding the past disaster experience. They are expected to transmit the risks and knowledge of high-risk low-frequency natural hazards, surviving over time and generations. This paper compares the perceptions to tsunami-originated placenames in local communities having realistic and exaggerated origins in Sanriku Coast, Japan. The reality of tsunami-originated placenames is first assessed by comparing the tsunami run-ups indicated in the origins and that of the tsunami in the Great East Japan Earthquake 2011 using GIS and digital elevation model. Considerable proportions of placenames had exaggerated origins, but the group interviews to local communities revealed that origins indicating unrealistic tsunami run-ups were more believed than that of the more realistic ones. We discuss that accurate hazard information will be discredited if it contradicts to the people’s everyday life and the desire for safety, and even imprecise and ambiguous information can survive if it is embedded to a system of local knowledge that consistently explains the various facts in a local area that requires explanation.
