摘要
对全球 1 90 0～ 1 980年 6级及以上地震 ,分级别统计了其时间 (年、月、日及月龄 )和地域 (经纬度 )的频度 ,及相应的能量分布。指出其结果具一定的特征和变化趋势 ,在地震频度与能量的谱分析 ,及频度与地球自转的相关性等方面 。
Based on the global earthquakes ( M ≥6) from 1900 through 1980, this paper derives their distributions of frequency and energy in respect of time (year, month, day, and month's age) and area (latitude and longitude) for the different magnitude. It also points out that there stand certain characteristic and variational tendency for further investigations, such as the seismal spectral analysis in the frequency and energy, the relationship between seismal frequency and the rotation of the earth and so on.
