摘要
利用福建及其周边3省(浙江、江西、广东)数字地震监测台网的69个宽频带台站一年的噪声记录,采用互相关技术提取两两台站间的瑞利面波格林函数,反演得到了福建及其周边地区3个周期段(T=4s、T=10s、T=15s)的瑞利面波群速度分布图像。所得结果可为研究该地区的地壳构造、地热分布、地震活动等提供重要依据。
The Green-function of Rayleigh wave between two stations was extracted by cross correlating a year velocity seismic noise records of 69 broad-band stations, which from four Digital Seismic Monitoring Networks of Fujian, Guangdong, Jiangxi and Zhejiang Provinces. And the group velocity distribution images of Rayleigh wave were inversed in three periods （ T=4s、 T=10s、 T=15s ） in Fujian and the surrounding. The results can provide important basis for the study of crustal structure, geothermal distribution and seismic activity in this area.Key words： noise recording;coherent stacking; tomography;rayleigh wave
