应用模糊相关方法，研究了日本海沟与我国华东地区地震活动的相关性。
In this paper, the correlativity of seismicity between in the trench area of Japan and in East China area has been studied.
结果表明在该地区很可能存在深层物质上升，从而表现出地震活动与P波速度场、Q值分布和VP/VS分布的相关性。
The results show that the deep substance may uprise in this area, so the distribution of P-wave velocity, Q value distribution and VP/VS distribution are closely related to seismicity in this area.
实际资料表明，地震活动与水库蓄水有明显的相关性。
The actual information indicates that there is obvious relativity between the seismicity and reservoir filling.
