| 摘 要： | 福建台网采用16个台湾台站记录的地震波形数据,选用适合台湾地区的地壳模型,通过CAP方法计算2018年2月台湾花莲海域4次6级以上地震的震源机制解。为验证计算结果的有效性和可靠性,将该计算结果分别与台湾中央气象局、美国地质调查局、Global CMT的结果进行对比研究,对比结果表明福建台网反演的震源机制解与全球其他台网的计算结果基本一致。通过本研究,进一步明确台湾区域构造动力学环境,也为福建台网日常化产出台湾地区地震震源机制解打下基础,还更加丰富福建台网对台湾地震的产品产出。

| Abstract: | Based on the seismic waveform data recorded by 16 seismic stations in Fujian seismic network, the CAP method and an appropriate crustal model were used to calculate the focal mechanism solutions of 4 M>6.0 earthquakes that occurred in the Hualien sea area of Taiwan in February 2018. To verify the reliability and effectiveness of the calculation results, the results were compared with those from the Taiwan Central Weather Bureau, US Geological Survey, and Global GMT. The comparison results show that the focal mechanism solutions from Fujian seismic network are basically consistent with those from other seismic networks. Through this research, the dynamic tectonic environment of Taiwan region is further clarified. Moreover, the study lays the foundation for routine products of focal mechanism solutions of Taiwan region from Fujian seismic network. |
