Identification of the 1870 M7¼ Batang earthquake surface rupture and its implications for tectonic transformation in the southeastern Tibetan Plateau

Yanbao Li, Lichun Chen, Luo Feng, Shihai Wang et autres

The southeastern Tibetan Plateau represents a crucial zone for eastward crustal extrusion, yet its active deformation mechanisms remain debated. This study focuses on the Batang fault within the Jinshajiang suture zone to clarify its role in present-day tectonics. Combining geomorphic mapping, trenching, …

Cenozoic Tectono‐Thermal Modeling of the Leiqiong Region, Beibuwan Basin, South China: Insights Into the Geodynamic Mechanisms of Late Cenozoic Volcanism

Qiongying Liu, Yiman Li, Yuanzhi Cheng, Y Zhang et autres

Abstract The Beibuwan Basin is a Cenozoic extensional basin whose Leiqiong region hosts the youngest intraplate volcanic field in South China. Although a mantle plume has been proposed for this magmatism, its location and timing, along with the crustal melting condition, remain …

Late Quaternary Fault Activity Along the Eastern Margin Fault of the Daxing Uplift, Southeast Beijing, China, and Implications for the Rupture Behavior of Intraplate Earthquakes

Yanbao Li, Zhengfang Li, Bengang Zhou, Jun Ma et autres

Abstract The mechanisms of seismic rupture behavior for large intraplate earthquakes remain poorly resolved. One important reason is the lack of sufficient paleoseismic data to constrain the spatiotemporal patterns of late Quaternary fault activity. In this study, we used drilling, paleoseismic trenching, …

Surface ruptures from the 1556 Huaxian earthquake, North China, measured using high-resolution topography: Implications for large magnitude normal-faulting earthquakes in continental interiors

Shengxue Lei, Richard Walker, Yanbao Li, Ji Ma et autres

On January 23, 1556, a large normal-faulting earthquake struck Huaxian county, in the eastern part of the Weihe Graben, North China. The direct effects of the great shock and the following famine, exposure to coldness, and disease together killed more than 830,000 …

Transition From Reverse to Left‐Slip on the Eastern Haiyuan Fault, NE Tibetan Plateau, From the Structure and Age of the Ganyanchi Pull‐Apart Basin

Shengxue Lei, Eric Cowgill, Ray J. Weldon, Yongkang Ran et autres

Abstract Because the active, left‐slip Haiyuan fault is a first‐order structure along the NE margin of the Tibetan Plateau, its tectonic evolution provides insight into deformation processes along this margin over time. Late Cenozoic deformation in the area of the eastern Haiyuan …

Rupture Behavior of the Litang Fault within the Sichuan-Yunnan Active Block, Southeastern Tibetan Plateau

Shuaipo Gao, Lichun Chen, Yanbao Li, Hu Wang et autres

Abstract In mainland China, approximately 86% of M≥7 earthquakes have occurred in the block boundary zone, which has been well explained by active block theory. However, a few large earthquakes have occurred within the active block, which provides us with an opportunity …

Evidence of Characteristic Earthquakes on Thrust Faults From Paleo‐Rupture Behavior Along the Longmenshan Fault System

Yongkang Ran, Xiwei Xu, Hu Wang, Wen‐Shan Chen et autres

Abstract The rupture behavior of large‐scale thrust faults has become an increasingly important topic in active tectonic and seismic studies. This is especially true for the 2008 Wenchuan earthquake (Mw 7.9), which occurred along the Longmenshan thrust fault (LMS) in China. While …

A Possible Tectonic Response Between the Qingchuan Faultand the Beichuan‐Yingxiu Fault of the Longmen Shan Fault Zone? Evidence From Geologic Observations by Paleoseismic Trenching and Radiocarbon Dating

Mingjian Liang, Yongkang Ran, Hu Wang, Yanbao Li et autres

Abstract The Qingchuan fault is located along the eastern margin of the Tibetan Plateau and connects to the Beichuan‐Yingxiu fault of the Longmen Shan fault zone (LMSF), which produced the 2008 MW 7.9 Wenchuan earthquake and 2013 MW6.6 Lushan earthquake. After the …
