Abstract

This paper presents the reconstruction results of catastrophic avalanche characteristics. The avalanche occurred on the slope of the Gora Otdelnaya ski resort on January 9, 2021 (Norilsk). It had a peak pressure of 0.266 MPa and led to the destruction of a suburban settlement, covering an area of about 0.9 ha. Six people got caught in the avalanch, of whom three were killed. The virtual and calculated boundaries of the maximum avalanche run-out distance are given. The causes of the catastrophe are also under investigation. An avalanche hazard assessment methodology for the Russian Arctic region and other poorly studied areas with no long-term avalanche observations is suggested.

低山雪崩危害评估，以 2021 年 1 月诺里尔斯克雪崩灾害为例

摘要

本文介绍了灾难性雪崩特征的重建结果。雪崩于2021年1月9日（诺里尔斯克）发生在Gora Otdelnaya滑雪胜地的斜坡上。它的峰值压力为 0.266 兆帕，导致郊区居民点遭到破坏，面积约 0.9 公顷。六人在雪崩中陷入困境，其中三人丧生。给出了最大雪崩跳动距离的虚拟和计算边界。灾难的原因也在调查中。建议对俄罗斯北极地区和其他没有长期雪崩观测的研究不足的地区采用雪崩危害评估方法。
