本文主要以卫星图象、电子计算机数字图象处理片和付里叶光学图象增强处理片为依据,对粤东泉汕地震带在海域内南延的影象特征,进行了初步分析.浅析结果认为:该带在南澳入海后,并末与南海北缘的滨海断裂带相接,而是按原方向继续向南西方向延伸。文中还讨论了该带所分出的三条亚带的影象强弱、连续的程度及其与地震活动的关系。
In this paper, based on the satellite image, the computer digital image processing film and the Fourier optical image enhancement processing film, the image features of the southward extension of the Quanzhou-Shantuan seismic belt in the East China Sea are analyzed. The results show that: After entering the sea in South Australia, the belt did not connect with the coastal fault zone on the northern margin of the South China Sea, but continued to extend to the southwest along the original direction. The paper also discusses the image strength and continuity of the three sub-belts and the relationship between them and the seismic activity.
