Using the 2017 Pohang earthquake in South Korea as a natural experiment, we examined the responses of the population. By constructing a counterfactual of Pohang using synthetic controls, we found that the earthquake significantly decreased the local population. To investigate the mechanisms of population decrease, we gathered administrative data on the universe of address changes and self-reported reasons for migration. While out-migration due to changes in the residential environment increased significantly, job-related migration showed little change. This out-migration also led to a depreciation in rental housing prices. Our results suggest that local residents perceived the earthquake as a negative amenity.

自然灾害、风险和迁移：来自 2017 年韩国浦项地震的证据

我们将 2017 年韩国浦项地震作为自然实验，研究了民众的反应。通过使用综合控制构建浦项的反事实，我们发现地震显着减少了当地人口。为了调查人口减少的机制，我们收集了有关地址变化范围和自我报告的迁移原因的行政数据。因居住环境变化而外出的人口明显增多，但因工作原因外出的人口变化不大。这种外流也导致出租房屋价格贬值。我们的研究结果表明，当地居民将地震视为一种消极的便利设施。
