2025年1月7日定日县震前哨兵2号遥感影像数据集

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，特共享震前哨兵2号遥感影像数据，其通过高分辨率多光谱成像卫星携带多光谱成像仪（MSI）监测得到，包括2A和2B两颗卫星数据，空间分辨率从10米到60米不等，其中可见光和近红外波段分辨率为10米，红边波段为20米，短波红外和大气波段为60米，该数据对震区紧急救援服务和灾情评估具有重要价值。

Officially confirmed by the China Earthquake Networks Center, a 6.8-magnitude earthquake occurred in Dingri County, Xigaze City, Tibet Autonomous Region at 09:05 on January 7, with a focal depth of 10 km and the epicenter located at 28.50°N, 87.45°E. To respond to this earthquake and facilitate researchers' analysis and study of the earthquake mechanism as well as the development of response measures, pre-earthquake Sentinel-2 remote sensing image data is hereby shared. This data was collected by high-resolution multispectral imaging satellites equipped with the Multispectral Imager (MSI), including datasets from both Sentinel-2A and Sentinel-2B satellites. The spatial resolution of the data ranges from 10 m to 60 m: the visible and near-infrared bands have a resolution of 10 m, the red-edge bands have a resolution of 20 m, and the short-wave infrared and atmospheric bands have a resolution of 60 m. This data holds important value for emergency rescue services and disaster assessment in the earthquake-affected area.
