2025年1月7日定日县地震区坡度数据

据中国地震台网正式测定，1月7日9时5分在西藏日喀则市定日县发生6.8级地震，震源深度10公里，震中位于北纬28.50度，东经87.45度。为应对此次地震，方便科研工作者分析、研究此次地震机理及提出应对措施，特共享地震区坡度数据。该数据集反映了区域地表的倾斜程度，以度数表示，是评估地质灾害风险的重要参数。这些坡度信息对于识别地震诱发的次生灾害易发区、评估山地灾害风险具有重要价值。可用于分析坡度与地震破坏程度的关系，预测潜在的滑坡、泥石流等地质灾害风险区域，为应急救援提供决策支持。Officially determined by the China Earthquake Networks Center (CENC), a magnitude 6.8 earthquake struck at 09:05 on January 7 in Dinggyê County, Xigazê City, Tibet Autonomous Region, with a focal depth of 10 km. The epicenter was located at 28.50° north latitude and 87.45° east longitude. To respond to this earthquake and facilitate researchers' analysis and study of the earthquake mechanism as well as the development of response countermeasures, the slope dataset of the earthquake-affected region is hereby publicly shared. This dataset reflects the inclination of the regional land surface, expressed in degrees, and serves as a critical parameter for assessing geological disaster risks. Such slope information is highly valuable for identifying earthquake-induced secondary disaster-prone areas and evaluating mountainous geological disaster risks. It can be utilized to analyze the correlation between slope and earthquake damage severity, predict potential risk zones of geological disasters such as landslides and debris flows, and provide decision-making support for emergency rescue operations.
