青藏高原关键部位地震监测数据集（2019-2020）

数据来源于课题组在帕米尔高原，天山造山带和塔里木盆地交汇区布设的20个宽频带流动地震台站，选址严格，记录周期是2019年10月至2020年7月。该数据集为P波初至前50 s和之后150 s的波形数据，事件震级大于等于6.0，震中距范围为30-95度。数据可被用于走时成像，剪切波分裂和接收函数等地震学方法，获得研究区的壳幔速度结构、典型间断面的深度和各向异性特征，为阐明印度-欧亚碰撞远程效应下的陆内变形机制提供重要约束。

This dataset is derived from 20 broadband mobile seismic stations deployed by the research group at the junction of the Pamir Plateau, Tian Shan Orogenic Belt and Tarim Basin, with rigorous site selection. The recording period spans from October 2019 to July 2020. This dataset contains waveform data ranging from 50 seconds before to 150 seconds after the P-wave first arrival, sourced from seismic events with magnitude ≥ 6.0 and epicentral distances between 30° and 95°. This data can be applied to seismological approaches including travel-time tomography, shear wave splitting and receiver function analysis, to derive the crust-mantle velocity structure, depths of typical discontinuities and anisotropic characteristics of the study area, thereby providing critical constraints for elucidating the mechanism of intracontinental deformation under the far-field effect of the India-Eurasia collision.
