据BBC报道，2025年5月28日，瑞士阿尔卑斯山脉的桦树冰川（Birch glacier）发生大规模滑坡，约350万立方米的冰雪和土石混合体，从海拔3500米的冰川山顶猛然崩塌，直接冲入位于1500米高度的河谷地带。滑落物质量初步估算约为900万吨，造成的地面震动强烈到连地震监测系统都记录到了3.1级的震动等级。此次灾害导致下方山谷的布拉滕村（Blatten）约90%的区域被掩埋，造成1人失联。
According to BBC reports, on May 28, 2025, a massive landslide occurred at the Birch Glacier in the Swiss Alps. Approximately 3.5 million cubic meters of ice, snow, and debris violently detached from the glacier summit at 3,500 meters above sea level and plunged into the valley at 1,500 meters elevation. The sliding mass, preliminarily estimated at 9 million metric tons, generated ground vibrations powerful enough to register a magnitude 3.1 event on seismic monitoring systems. The disaster buried nearly 90% of Blatten village in the valley below, leaving one person unaccounted for.

国家冰川冻土沙漠科学数据中心（以下简称数据中心）根据灾情，收集、制备基础地理数据、卫星遥感数据、人口数据、地形等应急响应科学数据。截止目前已开放提供25个服务数据集，服务数据量约33GB。已发布“瑞士瓦莱州布拉腾地区桦树冰川滑坡灾害（20250528）科学数据应急响应服务”系统，系统提供数据的可视化展示、互操作以及数据下载功能。供相关应急、救援和研究部门使用。
The National Cryosphere Desert Data Center (NCDC) collects and prepares basic geographic data, satellite remote sensing data, population data, topographic data and other emergency response scientific data based on disaster situations. The "Emergency response service of scientific data for Birch glacier landslide disaster in the Bratten area, Canton Valais, Switzerland (20250528)" system has been released, which provides data visualization, interoperation and data download capabilities. For use by relevant emergency, rescue and research departments.
后续数据中心将继续进一步收集、整理灾区各种数据资源并通过数据中心平台逐步发布，供相关应急、救援和研究部门使用。
The subsequent NCDC will continue to further collect and sort out various data resources in the earthquake area and gradually release them through the data center platform for the use of relevant emergency, rescue and research departments.
