2025年1月7日定日县地震应急震后遥感影像数据集

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，特共享震后遥感影像数据，包括陆探卫星数据（成像时间2025年1月7日14:19）、高分1号C星（成像时间2025年1月7日12:18）数据。陆探卫星数据可为地表形变分析和地质构造研究提供重要依据；高分1号C星数据则可用于地表特征精细识别和灾情评估。这些数据的综合应用将有助于深入理解地震发生机理，评估地震影响范围，为灾后重建和防灾减灾工作提供科学依据。Officially confirmed by the China Earthquake Networks Center, a 6.8-magnitude earthquake struck Dinggyê County, Xigazê City, Tibet Autonomous Region at 09:05 on January 7, with a focal depth of 10 kilometers. The epicenter is located at 28.50°N and 87.45°E. To respond to this earthquake and facilitate researchers' analysis of the earthquake mechanism and formulation of response measures, post-earthquake remote sensing image data are hereby shared, including land exploration satellite data (imaging time: 14:19, January 7, 2025) and Gaofen-1 C satellite data (imaging time: 12:18, January 7, 2025). The land exploration satellite data can provide important references for surface deformation analysis and geological structure research; the Gaofen-1 C satellite data can be used for fine-grained identification of surface features and disaster assessment. The comprehensive application of these data will help to gain an in-depth understanding of the earthquake occurrence mechanism, evaluate the earthquake impact scope, and provide scientific basis for post-disaster reconstruction and disaster prevention and mitigation work.
