We provide two datasets for tracking the debris flow induced by the 2008 Wenchuan Mw 7.9 earthquake on a section of the Longmen mountains on the eastern side of the Tibetan plateau (Sichuan, China). The database was obtained through a literature review and field survey reports in the epicenter area, combined with high-resolution remote sensing image and extensive data collection and processing. The first dataset covers an area of 892 km, including debris flows from 2008 to 2020 (an updated version). 186 debris flows affecting 79 watersheds were identified. 89 rainfall stations were collected to determine the rainfall events for the post-earthquake debris flow outbreak. The second database is a list of mitigation measures for post-earthquake debris flows, including catchment name, check dam number, coordinates, construction time, and successful mitigation date. The datasets can aid different applications, including the early warning and engineering prevention of post-earthquake debris flow, as well as provide valuable data support for research in related disciplines.
我们提供了两个数据集，用于跟踪 2008 年汶川 7.9 级地震在青藏高原东侧龙门山一段引发的泥石流。该数据库是通过对震中地区的文献回顾和野外调查报告，结合高分辨率遥感图像和广泛的数据收集和处理获得的。第一个数据集覆盖面积为 892km，包括 2008 年至 2020 年的泥石流（更新版本）。共识别出影响 79 个流域的 186 条泥石流。收集了 89 个雨量站，以确定震后泥石流爆发的降雨事件。第二个数据库是一份震后泥石流治理措施清单，包括集水区名称、拦砂坝数量、坐标、建设时间和成功治理日期。这些数据集可以为不同的应用提供帮助，包括震后泥石流的预警和工程防治，并为相关学科的研究提供有价值的数据支持。
