Permafrost and glaciers are being degraded by the warming effects of climate change. The impact that this degradation has on slope stability in mountainous terrain is the subject of ongoing research efforts. The relatively new availability of high-resolution (≤ 10 m) imagery with worldwide coverage and short (≤ 30 days) repeat acquisition times, as well as the emerging field of environmental seismology, presents opportunities for making remote, systematic observations of landslides in cryospheric mountainous terrain. I reviewed the literature and evaluated landslide activity in existing imagery to select five ~ 5000-km2 sites where long-term, systematic observations could take place. The five proposed sites are the northern and eastern flanks of the Northern Patagonia Ice Field, the Western European Alps, the eastern Karakoram Range in the Himalayan Mountains, the Southern Alps of New Zealand, and the Fairweather Range in Southeast Alaska. Systematic observations of landslide occurrence, triggers, size, and travel distance at these sites, especially if coupled with observations from in situ instrumental monitoring, could lead to a better understanding of changes in slope stability induced by climate change. The suggested sites are not meant to be absolute and unalterable. Rather, they are intended as a starting point and discussion starter for new work in this expanding landslide research frontier.

评估冰冻圈山区滑坡频率和幅度变化的风向标地点：呼吁进行系统、长期的观测以破译气候变化的影响

由于气候变化的变暖效应，永久冻土和冰川正在退化。这种退化对山区斜坡稳定性的影响是正在进行的研究工作的主题。相对较新的高分辨率（≤ 10 m）图像具有全球覆盖范围和短（≤ 30 天）重复采集时间，以及新兴的环境地震学领域，为对冰冻圈中的滑坡进行远程、系统观测提供了机会山区地形。我查阅了文献并评估了现有图像中的滑坡活动，以选择可以进行长期系统观测的 5 个 ~ 5000 平方公里的站点。五个拟建地点是北巴塔哥尼亚冰原的北部和东部侧翼、西欧阿尔卑斯山、喜马拉雅山脉的东部喀喇昆仑山脉、新西兰的南阿尔卑斯山和阿拉斯加东南部的费尔韦瑟山脉。对这些地点的滑坡发生、触发因素、大小和移动距离进行系统观测，尤其是与现场仪器监测的观测相结合，可以更好地了解气候变化引起的斜坡稳定性变化。建议的站点并不是绝对的和不可更改的。相反，它们旨在作为这个不断扩大的滑坡研究前沿的新工作的起点和讨论的开端。特别是如果结合现场仪器监测的观测结果，可以更好地了解气候变化引起的斜坡稳定性变化。建议的站点并不是绝对的和不可更改的。相反，它们旨在作为这个不断扩大的滑坡研究前沿的新工作的起点和讨论的开端。特别是如果结合现场仪器监测的观测结果，可以更好地了解气候变化引起的斜坡稳定性变化。建议的站点并不是绝对的和不可更改的。相反，它们旨在作为这个不断扩大的滑坡研究前沿的新工作的起点和讨论的开端。
