An inventory dataset of glacier and glacial lake related hazards (events) along the China-Pakistan Economic Corridor

The China-Pakistan Economic Corridor traverses the Karakoram Mountains and some Pamir Mountains where modern glaciers are widely distributed. The upstream glaciers and their evolution have caused various types of glaciers-related disasters (glacier floods/mudslides, glacier surges, paraglacial collapse/landslides, and ice-dammed lakes outburst floods, etc.) are particularly prominent, and increasingly pose a threat to the China-Pakistan Highway and its infrastructure and human activities. Based on the full excavation of various released data sets, this study collected the relevant disaster survey data, historical typical disaster events, and dynamics of the upstream glaciation area. Spatial information data of glaciers, glacial lakes and potential glacial floods/debris flow catchments along the China-Pakistan Highway have compiled. This dataset includes: (1) upstream watershed classification along the China-Pakistan Economic Corridor and basic background datasets such as glaciers, glacial lakes, and surface stream drainage systems; (2) surge glaciers distribution dataset; (3) distribution of historical outburst events of glacial ice-dammed lakes; (4) Potential glacier flood/debris flow gully distribution along the China-Pakistan Highway; (5) Landslide distribution data set and (6) historical seismicity data. This data set provides a basic scientific data support for the construction of the China-Pakistan Corridor, and can be used for the analysis and assessment of glaciers-related hazards along the China-Pakistan Economic Corridor.

中巴经济走廊（China-Pakistan Economic Corridor）穿越喀喇昆仑山脉与部分帕米尔山脉，该区域现代冰川广泛分布。上游冰川及其演化引发的各类冰川相关灾害（冰川洪水/泥石流、冰川跃动、冰缘崩塌/滑坡、冰碛湖溃决洪水等）尤为突出，且对中巴公路及其沿线基础设施与人类活动的威胁日益加剧。本研究在全面挖掘各类公开数据集的基础上，收集了相关灾害调查数据、历史典型灾害事件以及上游冰川区域的动态数据，编制了中巴公路沿线冰川、冰湖以及潜在冰川洪水/泥石流汇水区的空间信息数据集。本数据集涵盖以下六部分：（1）中巴经济走廊沿线上游流域分类及冰川、冰湖、地表水系等基础背景数据集；（2）冰川跃动分布数据集；（3）历史冰碛湖溃决事件分布数据；（4）中巴公路沿线潜在冰川洪水/泥石流沟分布数据；（5）滑坡分布数据集；（6）历史地震活动性数据。本数据集可为中巴经济走廊建设提供基础科学数据支撑，亦可用于中巴经济走廊沿线冰川相关灾害的分析与评估。
