摘要
研究了甘肃地区中强地震的时空分布特征.结果表明,1980～2001年,甘肃地区5级以上地震主要分布在祁连山地震带,地震的频发时段集中在6～10月;中强地震活动的分区特征显著,表疵为周期性及咸组性.
The spatial\|temporal features of moderate earthquakes in the Gansu region are studied. The results show that from 1980 to 2001 earthquakes with M≥5 in the Gansu region mainly occurred in the Qilianshan seismic zone frequently from June to October; and that the moderate earthquake activities were obviously distributed according to seismic regions, showing their periodicity and their occurrences in groups in each seismic belt.
