Abstract

The destruction of a major archaeological site in the 7th–9th centuries clearly demonstrates a lack of seismic knowledge of the region and, as a result, the neglected and underestimated seismic hazard assessment in the Alabash-Konur-Oleng Depression region near the southern border of the Issyk-Kul basin on the map of the Kyrgyz Republic. The aim of the field studies was to assess the consequences of a seismic event, to identify damage to the integrity of archaeological structures, and to estimate the strength of an earthquake in a given region. To search for archaeological sites, aerial photography of the site along the Akterek River was carried out—from the coast to the elevation of the Duvana Mountains. Field studies in the southern Issyk-Kul basin and the Alabash-Konur-Oleng Depression led to the discovery of an ancient destroyed complex on the southern slope of the Duvana Mountains. This structure, located on a seismotectonic scarp, was destroyed by it and absorbed by a seismotectonic graben. Most likely, a strong (I₀ ≥ 9) earthquake occurred during the complex’s existence, the 7th–9th centuries (?). There are other archaeological sites of various age in the Alabash-Konuroleng depression, bearing traces of the strongest seismic impacts, the study of which can help extend the seismic catalog for centuries and contribute to a more accurate seismic hazard assessment of the area of currently rising uplifts—the Adyrs (foothills) of the Terskey Ala-Too Range.

天山西南伊塞克湖盆地强地震摧毁了中世纪考古纪念碑

摘要

在7至9世纪，一个主要考古遗址的破坏清楚地表明该地区缺乏地震知识，结果，该地区南部边界附近的Alabash-Konur-Oleng洼地地区的地震灾害评估被忽视并被低估了。吉尔吉斯共和国地图上的伊塞克湖盆地。现场研究的目的是评估地震事件的后果，确定对考古结构完整性的破坏，并估计给定地区的地震强度。为了寻找考古遗址，对沿阿克特雷克河的遗址进行了航空摄影-从海岸到杜瓦纳山脉的海拔。在伊塞克湖南部盆地和阿拉巴什-科努尔-奥伦格洼地的野外研究导致在杜瓦纳山脉南坡发现了一座古老的被毁建筑。这个位于地震构造陡峭带上的结构被它破坏并被一个地震构造抓钩吸收。最有可能的是，我₀复杂的存续期间发生≥9）地震发生后，7日至9世纪（？）。Alabash-Konuroleng洼地还有其他不同年龄的考古遗址，带有最强烈的地震影响痕迹，其研究可以帮助将地震目录扩展几个世纪，并有助于对当前上升地区进行更准确的地震危险性评估隆升-Terskey Ala-Too山脉的Adyrs（山麓）。
