【摘要】 通过对 1 998～ 2 0 0 0年 7月内蒙古乌拉特前旗地区的地震活动 (包括西山咀震群 )特征及一些测震学指标变化特征的分析 ,研究了该地区未来地震的活动趋势 .认为未来 1年内该区发生 6.0级以上中强地震的可能性不大 ,但可能发生 4级或 5级左右的地震 .沿经度和纬度的震源深度剖面上显示的空区 ,可能是未来能量积累的区域更多还原

【Abstract】 Based on the analysis on seismicity and variations of some seismometry indices in Wulateqianqi region,Inner Mongolia from 1998 to July,2000, seismicity trend of the region in future is studied. It is believed that there is a little possibility of M S 6.0 earthquake to occur in a future year,but there is a larger one of events with magnitude of about 4 or 5 to occur.The gaps on focus depth sections along longitude or latitude may be risk regions of coming strong earthquakes.更多还原
