В большинстве случаев распределение эпицентров землетрясений контролируется локальными меридиональными структурами, входящими в состав данного тектонического пояса. Изучение современного напряженного состояния тектонического пояса Шаньси вносит вклад в понимание взаимоотношений между проявлением сильных землетрясений и их структурным распределением, а также содействует оценке региональной сейсмической опасности и выделению регионов, где в будущем возможны сильные землетрясения. С применением метода катакластического анализа (Cataclastic Analysis Method, CAM) проведена реконструкция напряженного состояния на базе данных о механизмах очагов землетрясений, зарегистрированных в тектоническом поясе Шаньси с 1967 г. по 2010 г. Результаты исследования показали, что ориентации осей максимальных главных напряжений сжатия в тектоническом поясе Шаньси, возможно, подвергались изменениям как до, так и после сильного Куньлунского землетрясения (MS=8.1), произошедшего в 2001 г., при этом в разные временные периоды выделены два разных тренда – северо-западной и северо-восточной ориентации. При ориентации оси максимального главного напряжения сжатия в северо-восточном направлении на схеме пространственного распределения сейсмических событий в тектоническом поясе Шаньси видна тенденция концентрации землетрясений в тектонических сегментах, ориентированных в меридиональном направлении. При этом зарегистрированное напряженное состояние характеризуется горизонтальным сдвигом и горизонтальным растяжением локальных сегментов, ориентированных в меридиональном и северо-восточном направлении. При ориентации оси максимального главного напряжения сжатия в северо-западном направлении напряженное состояние на тектонических сегментах, ориентированных в меридиональном и северо-восточном направлении, в основном определяется как горизонтальный сдвиг. Оценка углов погружения осей напряжений показывает, что сейсмичность тектонического пояса Шаньси коррелирует главным образом с активностью пологих разломов, при этом участки разломов с большими углами наклонов осей напряжений располагаются в северо-восточных тектонических сегментах пояса, подверженных растяжению. Результаты исследований показывают, что современное напряженное состояние тектонического пояса Шаньси изменяется в связи с вариациями регионального поля напряжений.</p></abstract><trans-abstract xml:lang="en"><p>The Shanxi tectonic belt is a historically earthquakeabundant area. For the majority of strong earthquakes in this area, the distribution of earthquake foci was controlled by the N–S oriented local structures on the tectonic belt. Studies of the present stress state of the Shanxi tectonic belt can contribute to the understanding of the relationship between strong earthquakes’ occurrence and their structural distribution and also facilitate assessments of regional seismic danger and determination of the regions wherein strong earthquakes may occur in future. Using the Cataclastic Analysis Method (CAM), we performed stress inversion based on the focal mechanism data of earthquakes which took place in the Shanxi tectonic belt from 1967 to 2010. Our results show that orientations of the maximum principal compressive stress axis of the Shanxi tectonic belt might have been variable before and after the 2001 Kunlun MS=8.1 strong earthquake, with two different superior trends of the NW–SE and NE–SW orientation in different periods. When the maximum principal compressive stress axis is oriented in the NE–SW direction, the pattern of the space distribution of the seismic events in the Shanxi tectonic belt shows a trend of their concentration in the N–S oriented tectonic segments. At the same time, the stress state is registered as horizontal shearing and horizontal extension in the N–S and NE–SW oriented local segments in turn. When the maximum principal compressive stress axis is NW–SE oriented, the stress state of the N–S and NE–SW oriented tectonic segments is primarily registered as horizontal shearing. Estimations of plunges of stress axes show that seismicity in the Shanxi belt  corresponds primarily to the activity of lowangle faults, and highangle stress sites are located in the NE–SW oriented extensional tectonic segments of the Shanxi belt. This indicates that the stress change of the Shanxi belt is caused by adjustment of the regional stress field, rather than by the diverse seismic activities.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>тектонический пояс Шаньси</kwd><kwd>состояние напряжения</kwd><kwd>Куньлунское землетрясение (MS=8.1)</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Shanxi tectonic belt</kwd><kwd>stress state</kwd><kwd>the 2001 Kunlun MS=8.1 earthquake</kwd></kwd-group><funding-group><funding-statement xml:lang="en">Prof. Yuri L.
