Rayleigh and Love waves Group Velocity Dispersion Data

A total of 1286 Rayleigh and 1048 Love wave group velocity dispersion curves are obtained using waveforms of 77 regional earthquakes (Mw 4.8-7.0), that occurred within the Indian subcontinent and adjoining regions during 2010-2015, recorded by 38 stations of a network operated by the Institute of Seismological Research, equipped with 120 s triaxial broadband seismographs. The fundamental mode Rayleigh and Love wave dispersion curves are obtained from the vertical and transverse components of the waveforms, respectively, using the Frequency-Time Analysis (FTAN).本数据集依托2010至2015年间发生于印度次大陆及邻区的77次区域地震（矩震级Mw 4.8~7.0）的波形数据构建，共包含1286条瑞利波（Rayleigh）群速度频散曲线与1048条勒夫波（Love）群速度频散曲线。上述地震的波形由印度地震研究所（Institute of Seismological Research）运营的台网中的38个观测台站记录，该台网配备120秒三轴宽频带地震仪。本研究中，基阶瑞利波与勒夫波的频散曲线分别从波形的垂直分量与横向分量中提取，所用方法为时频分析（FTAN）。
