| 摘 要： | 在较详细分析华东地区1970年以来中等地震活动规律的基础上,对华东地区中等地震活动条带及迁移规律进行了研究,发现该地区的中等地震活动具有由西向东的整体性迁移特征,其迁移速率约25 km/a,可能起源于地幔应力波.对华东地区而言,目前东部的北西向条带北部,是未来最有可能出现"关门"地震的区域.该项研究为地震趋势的判断提供了一种参考. |
| 关 键 词： | 华东地区 中等地震 条带迁移 "关门"地震 |

| Abstract: | Based on the study of the medium earthquake activity since 1970, we have found the activity belt and the migration rule in East China. The result shows that the medium earthquake activity belt migrated from west to east. The migrating velocity is about 25 krn/a, this maybe comes of the stress wave of the mantle. For East China, the northern part of this NW earthquake belt maybe comes to a shutdown earthquake in the future. Our research may be useful in the uptrend estimate. |
| Keywords: | East China medium earthquake migration of the earthquake belt shutdown earthquake |
