本文选取泉州台近年来各种长短周期地震仪所记录到的地震图纸资料,结合地质构造背景和地震空间分布特点,研究泉州台震中距Δ<500km范围内,闽台地区天然地震的震相记录特征和有关区域内某些已知、未知震相的出现规律,讨论闽、台震相特征所存在的一些异同点,比较震中方位、震源深度、震中距、地震强度、仪器频率特性等有关因素,对各区震相特征所产生的影响,从而取得与闽台地区震相分析有关的新认识。
In this paper, seismograms recorded by various long-short period seismographs in Quanzhou station in recent years are selected. Based on the geological tectonic setting and the spatial distribution of the earthquake, the seismic record of natural earthquakes in Fujian and Taiwan regions Characteristics and relevant rules of some known and unknown seismic facies in the region are discussed. Some similarities and differences of seismic facies in Fujian and Taiwan are discussed. Comparisons of relevant factors such as epicentral position, focal depth, epicentral distance, seismic intensity, instrument frequency characteristics , The impact of the characteristics of the earthquake facies in each area, so as to gain new understanding about the seismic phase analysis in Fujian and Taiwan.
