藏东南派墨测线短周期密集地震台阵远震波形数据

派墨测线位于青藏高原东南部，它北起鲁朗镇，南至背崩乡，全长近100 km。远震波形数据来源于2021年6月沿剖面布设的50个短周期地震台站，台间距为2 km。台站选址严格，工作时长是28天。该数据集为P波初至之前50s，之后150 s的波形数据, 采样率是100Hz, 事件震级大于等于5.5，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，为理解东构造结的构造演化过程提供重要约束。

The Paimo seismic profile is located in the southeastern Tibetan Plateau, extending northward from Lulang Town and southward to Beibeng Township, with a total length of nearly 100 km. Teleseismic waveform data were collected from 50 short-period seismic stations deployed along the profile in June 2021, with a station spacing of 2 km. The station sites were rigorously selected, and the stations operated for a period of 28 days. This dataset contains waveform data covering 50 seconds before and 150 seconds after the P-wave first arrival, with a sampling rate of 100 Hz. The included seismic events have magnitudes of 5.5 or greater, and epicentral distances ranging from 30° to 95°. The data can be applied to seismic research methods including travel-time tomography, shear-wave splitting analysis, 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 understanding the tectonic evolution of the Eastern Himalayan Syntaxis.
