Haiti Landslide Dataset

A strong magnitude earthquake (Mw 7.2) struck Haiti on August 14, 2021, triggered massive landslides in the island nation. The epicenter of the earthquake was located at 18.434° N, 73.482° W, at a depth of 10 km in the Nippes region. We mapped all the coseismic landslides triggered during the 2021 event from Landsat 8 OLI, Sentinel-2 and Google Earth archived images. A total of 4178 landslide polygons, equaling 26.84 km²area were delineated.2021年8月14日，海地发生矩震级（Mw）7.2级强震，触发了这座岛国的大规模山体滑坡。此次地震的震中位于尼普斯（Nippes）地区，地理坐标为北纬18.434°、西经73.482°，震源深度10千米。本研究基于陆地卫星8号OLI（Landsat 8 OLI）、哨兵2号（Sentinel-2）及谷歌地球（Google Earth）的存档影像，对2021年此次地震触发的全部同震滑坡进行了解译与制图，最终共勾绘出4178处滑坡多边形，总面积达26.84平方千米。
