摘要
托里活断层、达尔布特活断层、独山子—安集海活断层及霍尔果斯—卡子湾活断层是塔城地区主要的全新世活断层，均有过多次古地震活动。自１９７７年以来，４级以上地震活动的空区在裕民县西北。据活断层古地震活动复现期及地震活动围空特点分析，今后１０年北天山或塔城西北可能有发生６级左右地震的危险。
Tuoli active fault,Daerbute active fault, Dushanzi-Anjihai active fault and Huoerguosi-Kaziwan active fault are main Holocene active faults in Tacheng area. There were many paleoquakes occurred along these faults. Since 1977,a gap surrounded by earthquake with Ms≥4 has been formed in northwest part of Yumin county. According to recurrence period of paleoquakes and gap characteristics of seismic activity, it is possible that an earthquake with Ms6.0 would occurr in North Tianshan or northwest of Tacheng in coming 10 years.
