2025年1月7日定日县地震信息数据集

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，特共享地震信息数据集。本次发布的数据包括震中位置点数据以及不同范围的缓冲区数据（10公里、50公里、100公里和200公里）。这些分区数据可用于多个研究方向：震中周边地质环境分析、地震波传播特征研究、地震影响范围评估、灾害损失分级统计等。其中，10公里缓冲区主要用于震中核心区域研究，50公里和100公里缓冲区可用于评估中度影响区域，200公里缓冲区则用于分析地震波及范围和远场效应。这些数据的分层分析将有助于全面评估地震影响程度，为应急救援决策和灾后重建规划提供科学依据，同时也为地震预警体系完善提供重要参考。

Officially determined by the China Earthquake Networks Center, a magnitude 6.8 earthquake struck Dinggyê County, Xigazê City, Tibet Autonomous Region at 09:05 on January 7, with a focal depth of 10 km. The epicenter was located at 28.50° north latitude and 87.45° east longitude. To address this earthquake and enable researchers to analyze the seismogenic mechanism of the event and develop response measures, we hereby share this seismic information dataset. The dataset released this time includes the epicenter location point data as well as buffer zone data of multiple ranges: 10 km, 50 km, 100 km, and 200 km. These zoned datasets can support a variety of research directions, including analysis of the geological environment surrounding the epicenter, research on seismic wave propagation characteristics, assessment of earthquake impact scope, and graded statistical analysis of disaster losses, among others. Specifically, the 10 km buffer zone is primarily intended for research on the core area around the epicenter; the 50 km and 100 km buffer zones can be used to assess moderately affected regions; and the 200 km buffer zone is designed for analyzing the seismic wave propagation range and far-field effects of the earthquake. Hierarchical analysis of these datasets will facilitate a comprehensive assessment of the earthquake's impact, provide scientific evidence for emergency rescue decision-making and post-disaster reconstruction planning, and serve as an important reference for the improvement of earthquake early warning systems.
