Abstract—

The article provides data on the geological, tectonic, and seismological situation of the region. Results of archeoseismological field studies of the ancient fortress and castle of Mugkala and Mugtepa in the Fergana Valley (Namangan region, Uzbekistan) are considered. At the archeological sites, we revealed such characteristic destruction and damage as wedges, inclinations, shaking, sagging, and extend through cracks and interbrick cracks in city walls, confirming their seismogenic origin. Similar seismic deformations can be considered as evidence of the high local seismic oscillation intensity. It was noted that seismic shocks propagated along the sublatitudinal axis. Both the Mugtepa and Mugkala archeological sites are located between the North Fergana Fault and North Fergana flexural-fracture zone. The seismicity of the research area is associated with the development of the Kasansay group of young Quaternary anticlinal folds. A new residence on Mugtepa could have been built by new kings of the Fergana Valley at the end 1st century BCE, which was destroyed in the 1st century CE by a strong earthquake with a local seismic intensity of I_L = VIII–IX (MSK-64 scale). The residence of the Turkic Khaganate could have been built by new kings of Fergana Valley in a new location. Mugkala could also have been destroyed by a strong earthquake with a seismic intensity of I_L = VIII–IX (MSK-64 scale) at the end of the 8th century CE. This earthquake caused the various deformations described in the paper.

Mugkala和Mugtepa考古遗迹中的地震变形（乌兹别克斯坦费尔干纳凹陷）

摘要-

本文提供了有关该地区的地质，构造和地震情况的数据。考虑了在费尔干纳山谷（乌兹别克斯坦纳曼根地区）的穆格卡拉和穆格塔佩古城堡和城堡进行的考古现场研究的结果。在考古现场，我们发现了特征性破坏和破坏，例如楔形，倾斜，晃动，下垂，并延伸到城墙的裂缝和砖间裂缝，证实了它们的成因。可以将类似的地震变形视为高局部地震振荡强度的证据。值得注意的是，地震波是沿着子纵轴传播的。Mugtepa和Mugkala考古遗址都位于北费尔干纳断层和北费尔干纳弯曲断裂带之间。研究区的地震活动与年轻的第四纪背斜褶皱的Kasansay组的发展有关。公元前1世纪末，费尔干纳山谷的新国王可能会在Mugtepa上建造新的住所，而公元1世纪末，该地区在当地地震烈度为1的强烈地震中被摧毁。I _L = VIII–IX（MSK-64等级）。土库曼斯坦卡加纳特人的住所本来可以由新的费尔干纳山谷国王在新的地点建造。Mugkala也可能在公元8世纪末被强地震摧毁，地震烈度为I _L = VIII–IX（MSK-64尺度）。地震造成了本文所述的各种变形。
