阿拉斯加利用70年的数据在线发布滑坡地图,以协助进行风险评估。 Alaska launches online landslide map using 70 years of data to aid risk assessment.

阿拉斯加自然资源部启动了一个在线数据库,从1950年代的1 000多份地质报告中收集了全州数千起过去山崩的分布图。 The Alaska Department of Natural Resources has launched an online database mapping thousands of past landslides across the state, compiled from over 1,000 geologic reports dating to the 1950s. 该工具是三年来开发的,利用航空图像和专家分析来确定滑坡地点,暴露出东南阿拉斯加和北布鲁克斯山脉的高度风险。 The tool, developed over three years, uses aerial imagery and expert analysis to identify landslide locations, revealing high risk in Southeast Alaska and the northern Brooks Range. 虽然像北斯隆这样的一些地区似乎没有标记,但官员们说,这可能反映了数据上的空白,而不是没有山崩。 While some areas like the North Slope appear unmarked, officials say this likely reflects gaps in data, not absence of landslides. 该清单帮助社区、研究人员和机构评估风险和改善规划,并将大大更新美国地质调查局的国家山崩数据库。 The inventory helps communities, researchers, and agencies assess risks and improve planning, and will significantly update the U.S. Geological Survey’s national landslide database.
