| 摘 要： | 以MS5.5以上地震是否发生为标记, 划分华南地区的活跃和平静时段, 结果显示与华南地区2级以上地震频次的应力调制时间过程变化趋势有很好的一致性。 另外, 在活跃和平静时段华南地区的震级频次特点显著不同。 华南地区在中强震发生前有4级左右地震频繁活动和小震群频发的特点。 华南地区的中强震与云南地区7级地震的发生相关。 统计20世纪以来台湾强震与华南中强震的对应关系, 台湾西带6级强震后1年内华南中强震的对应率近0.5, 地区影响似有由东至西逐渐减弱的趋势。 台湾7级地震后2年内华南中强震的对应率只有0.3, 对应地区除台湾海峡、 福建和广东东部地震外, 也有几次对应广西和北部湾地区的地震, 与6级相比, 台湾7级强震影响范围大。 |

| Abstract: | Taking the phenomenon whether the earthquakes with M≥5.5 occur or not as the sign, the seismically active and quiet periods can be divided in the South China region. The research results show well the consistency with the time change trend of stress modulation of seismic frequency (≥ML 2.0). Besides, the features of seismic frequency during the active and quiet periods are obviously different. Before the moderately strong earthquakes in the region there are frequent seismic activity with magnitude of 4 or so and small earthquake swarms. The moderately strong earthquakes in South China region are related to occurrence of earthquakes with magnitude of 7 or so in Yunnan region. According to the statistical corresponding relation between seismicity in Taiwan and South China regions since 20th century, it is found that the corresponding rate of moderately strong earthquakes in South China to the earthquakes with magnitude of 6 or so in western Taiwan occurred in one year is 0.5; and the corresponding rate of moderately strong earthquakes in South China to the earthquake with magnitude of 7 or so in two years is 0.3. The corresponding regions include Taiwan straight, Fujian Province and eastern Guangdong areas, and Guangxi and Beibu Bay areas are also involved. Compared with MS 6 earthquakes, the Taiwan MS 7 earthquakes show larger effected range. |
