The earthquake measured 6.7 and 6.6 on the surface-wave and moment magnitude scales, respectively. It occurred at a depth of 10 km. The earthquake resulted in one fatality and left approximately 11,000 people homeless. Tectonic setting Mainland China is located on the eastern margin of the Eurasian seismic belt. The eastern and southwestern parts of the mainland are respectively affected by the convergence of the Pacific Plate and the Indian Plate, resulting in frequent seismic activity and significant earthquake hazards. Xinjiang lies along the foreland zone where the Indian Plate subducts beneath the Eurasian Plate, making the region especially prone to earthquakes.张志斌 朱浩清 李艳永 基于地震波反演研究南天山中西段的震源深度 Research on Focal Depths in the Central and Western Segments of the South Tianshan Mountains Based on Seismic Wave Inversion 震灾防御技术 2015 10 S1 701–711 http://www.wanfangdata.com.cn/details/detail.do?_type=perio&id=zzfyjs2015z1001 2018-04-12 https://web.archive.org/web/20180412113333/http://www.wanfangdata.com.cn/details/detail.do?_type=perio&id=zzfyjs2015z1001 2018-04-12 live zh-cn Since the beginning of the 21st century, mainland China has experienced a period of heightened seismic activity. A series of major earthquakes have occurred in the North–South Seismic Belt and Xinjiang, including the 2015 Nepal earthquake. Following that event, a number of intermediate- and deep-focus earthquakes occurred in the western segment of the Himalayan seismic belt around the Hindu Kush and in its eastern segment around the Burmese Arc, indicating a strengthening of the northeastward compression exerted by the Indian Plate. The area where the epicenter of this earthquake was located had entered a prolonged period without earthquakes of magnitude 5.0 or greater following the June 1, 2012, 2012 Wuqia earthquake (M5.1). After the 2015 Pishan earthquake, overall seismic activity in Xinjiang declined markedly, and the frequency of earthquakes of magnitude 2.0 and above decreased rapidly.聂晓红 王琼 吴传勇 2016年11月25日阿克陶M_S6.7地震序列特征及后续趋势分析 内陆地震 2017 31 2 97–109 zh-hans http://kns.cnki.net/KCMS/detail/detail.aspx?filename=lldz201702001&dbname=CJFD&dbcode=CJFQ 2018-04-11 https://web.archive.org/web/20180411124041/http://kns.cnki.net/KCMS/detail/detail.aspx?filename=lldz201702001&dbname=CJFD&dbcode=CJFQ 2018-04-11 live The area near the epicenter of the earthquake is located at high altitude and is sparsely populated, but has historically experienced frequent strong earthquakes. Within 100 kilometres (62 mi) of the epicenter, 17 earthquakes of magnitude 6.0 or greater have been recorded, including four earthquakes of magnitude 7.0 or above: the 28 September 1944 Wuqia South earthquake (M7.0), the twin Wuqia West earthquakes of 15 April 1955 (M7.0), and the 11 August 1974 Wuqia Southwest earthquake (M7.3). The closest magnitude-7 earthquake to this event was the 1974 Wuqia earthquake, located approximately 25 kilometres (16 mi) from the epicenter. The most recent significant earthquake in the area was the 26 June 2016 2016 Kyrgyzstan earthquake (M6.7), which occurred about 58 kilometres (36 mi) from the epicenter of this earthquake. Historically, 86% of the fourteen earthquake sequences of magnitude 6.0 or greater recorded within 100 kilometres (62 mi) of the area were classified as mainshock–aftershock sequences, with the largest aftershocks reaching about magnitude 5.5. Although global seismic activity was relatively active around the time of the earthquake, an official from the China Earthquake Networks Center stated that uneven temporal distribution is a normal characteristic of global seismicity, with some periods experiencing concentrated earthquake activity and others remaining relatively quiet.http://www.cea.gov.cn/publish/dizhenj/468/553/102420/102421/20161127084444404640159/index.html 解读新疆阿克陶6.7级地震：不会导致大的人员伤亡 2016-11-27 2018-02-06 zh-hans https://web.archive.org/web/20180206131654/http://www.cea.gov.cn/publish/dizhenj/468/553/102420/102421/20161127084444404640159/index.html 2018-02-06 dead Responses According to the China Earthquake Networks Center (CENC), a strong earthquake struck western Akto County, Kizilsu Kyrgyz Autonomous Prefecture, Xinjiang, China, at 22:24:30 CST on 25 November 2016. The earthquake had an epicenter at 39.27°N, 74.04°E and a magnitude of s 6.7, with a focal depth of approximately 10 km (6.2 mi). The United States Geological Survey (USGS) reported slightly different parameters, locating the epicenter at 39.273°N, 73.978°E.

Following this earthquake, a surface rupture zone approximately 1 km (0.62 mi) long was identified near the epicenter. Multiple extensional fissures ranging from 1 to 46 cm (0.4–18.1 in) in width were observed. Most of these ruptures were formed by north–south extension.胡伟华 刘培玄 杨新红 2016年阿克陶M_S6.7地震地表破裂特征和帕米尔现代构造应力场初步分析 震灾防御技术 2017 4 zh-hans http://kns.cnki.net/KCMS/detail/detail.aspx?filename=zzfy201704005&dbname=CJFD&dbcode=CJFQ 2018-04-11 https://web.archive.org/web/20180411125814/http://kns.cnki.net/KCMS/detail/detail.aspx?filename=zzfy201704005&dbname=CJFD&dbcode=CJFQ 2018-04-11 live Using waveform data from 53 earthquakes of magnitude 3.0 and above that occurred near the source region, Gao Rong and Xia Aiguo of the Xinjiang Earthquake Agency analyzed the source parameters of the earthquake sequence. They found that moment magnitude, source radius, and seismic moment increased with earthquake magnitude, showing a positive correlation. In contrast, corner frequency decreased as magnitude increased, indicating a negative correlation. The study also found that stress drop exhibited a multiscaling relationship with earthquake magnitude.高荣 夏爱国 2016年11月25日新疆阿克陶Ms6.7地震序列应力降变化特征 内陆地震 2017 31 2 122–129 zh-hans http://kns.cnki.net/KCMS/detail/detail.aspx?filename=lldz201702004&dbname=CJFD&dbcode=CJFQ 2018-04-11 https://web.archive.org/web/20180411125814/http://kns.cnki.net/KCMS/detail/detail.aspx?filename=lldz201702004&dbname=CJFD&dbcode=CJFQ 2018-04-11 live Impact and relief efforts According to local authorities, the epicenter was located in a mountainous area, and shaking was felt in Akto County.
