舟山地震台周围海域常进行人工爆破试验,其波形与天然地震(以下简称地震)相似,不易区别,给分析带来困难。经台站一年多的记录,积累了不少资料,通过对这些资料的整理、分析,初步认为海上爆破记录有如下特征。 Artificial blasting tests are often conducted in the waters around Zhoushan Seismic Station. The waveforms are similar to those of natural earthquakes (hereinafter referred to as earthquakes) and are not easy to be distinguished from each other, which brings difficulties to the analysis. After more than a year of station records, a lot of information has been accumulated. According to the collation and analysis of these data, the records of sea blasting are preliminarily thought to have the following characteristics.
