| 摘 要： | 研究了2005年2月15日乌什6.2级地震前3个月中在乌什附近形成的北西向小震条带.结果表明,条带中显著地震震级上升,其发震时间间隔缩短,且显著地震发震时引潮力矢量相互之间的交角较小,引潮力水平矢量相互之间的交角也较小,引潮力水平矢量方向接近于地震断层面走向.

| Abstract: | The small earthquake belt along the line of Northwest around Wushi which in three months before Wushi Ms6.2 earthquake on February. 15, 2005 was studied. The results showed, the magnitude of significant earthquakes rose, the time interval between two significant earthquakes reduced; when significant earthquakes occurred, their angles between two vectors of tidal force became less; the angles between two vectors of horizontal tidal force became less too, and the vector of horizontal tidal force was near to the strike of seismic fault plane. |
