2025年1月7日定日县地震应急背景数据集

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，包括陆地探测卫星数据（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。陆地探测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。 该数据集以tif格式给出。Officially determined by the China Earthquake Networks Center, a M6.8 earthquake struck Tingri County, Xigaze City, Tibet Autonomous Region at 09:05 on January 7, with a focal depth of 10 km. The epicenter was located at 28.50° N and 87.45° E. To respond to this earthquake and facilitate researchers to analyze the earthquake mechanism and propose 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). Land Exploration Satellite data can provide important basis for surface deformation analysis and geological structure research; Gaofen-1 C satellite data can be used for fine surface feature identification and disaster assessment. The comprehensive application of these data will help to deeply understand the earthquake occurrence mechanism, evaluate the earthquake impact scope, and provide scientific support for post-disaster reconstruction and disaster prevention and mitigation work. This dataset is provided in TIFF format.
