对阿尔金断层上发现的古地震震中塌陷、滑塌、古地震断层、古地震楔及断错水系的初步研究表明,阿尔金断层自全新世以来发生过8次古地震事件。其中以1200年前的事件强度最大,震级可达8级以上。其余事件一般均在7级左右。阿尔金断层古地震最短复现间隔时间可能为300年左右。
Preliminary studies on the epicenter collapses, slumps, paleoseismic faults, paleoseismic wedges and fault-broken water systems of the ancient earthquakes discovered on the Altyn Tagh fault show that the Altyn Tagh fault occurred 8 times since the Holocene. One of the largest event intensity 1200 years ago, the magnitude of up to 8 or more. The rest of the incident are generally about 7. The shortest recurrence interval of Altyn Tagh fault may be about 300 years.
