“…Structural planes and their combinations have played an important role in the stability of rock-soil mass slopes (Gu and Wang, 1979;Lv et al, 2014). The stability of the YJSF is related to the coupling action of endogenic and exogenic geological processes.…”

“…A series of observations and research studies have been conducted worldwide on the influences of rock mass structure planes for the slope stability (Lv et al, 2014;Stead and Wolter, 2015). Müller et al (1970) realized the importance of structure planes to the mechanical characteristics and stability of rock masses; Gu and Wang (1979) put forward the control theory of rock mass structures, clarifying that the existence of rock mass structural planes has an important control effect on the deformation and failure of rock masses.…”

The Yellow River Jingtai Stone Forest (YJSF) is situated in the northwestern margin of the Chinese Loess Plateau, and it is not only one of the most precious and rare types of natural landforms in the Loess Plateau but also a protected area of valuable geological relics and landscapes in northwest China. Massive rock structural planes are present in the stone forest. However, few studies have been conducted on the rock mass structural planes for the slope’s stability. Based on the detailed field investigation, structural planes and their combination types are classified based on the rock mass. On this basis, combined with physical, mechanical, and hydraulic tests, the disaster-induced mechanism of the rock mass structural planes is classified and discussed. Results show that the structural planes of the YJSF can be divided into three types, namely, the primary structural plane, tectonic structural plane, and secondary plane. They not only combine with each other to cut the rock mass into different shape blocks but also jointly control the stability of the rock mass slope. The physical and mechanical tests and water sensitivity characteristics show that the conglomerates and muddy sandstones which are the main components of the YJSF have strong tensile and shear strengths under natural situations, while their strengths are reduced under immersion infiltration; in particular, the muddy sandstones are more sensitive to water and have a lower strength than that of the conglomerates. Finally, the disaster-induced mechanism of the YJSF is mainly related to the combination of various structural planes, which can be divided into four failure patterns, namely, creeping slide-tension failure, gradual failure, slipping failure, and dumping failure; coupling action of endogenic and exogenic geodynamic processes was responsible for their formation. The studied results will provide critical, theoretical, and technical support for the slope stability analysis, scenic geological heritage protection, and disaster warning in this area.

“…In case of historical failures, only generic information about the triggering earthquake is available, while in the second one (landslide occurred during the Holocene), it is often difficult to recognize with certainty the earthquake as triggering factor. In these articles, the authors often use terms that refer to the possible nature of the landslide trigger, such as: "was probably triggered" (Pérez-López et al, 2019) or "most likely triggered" (Lv et al, 2014). In this group, several authors also describe dating techniques, such as dendrochronological (e.g., Struble et al, 2020), lichenometric (e.g., Pérez-López et al, 2019) and isotopic analyses (e.g., Kojima et al, 2014).…”

Abstract. Over the last two decades, the topic of earthquake-triggered landslides (EQTLs) has shown an increasing relevance in the scientific community. This interest is confirmed by the numerous articles published in the international, peer-reviewed journals. In this work we present a database containing a selection of articles published on this topic from 1984 to 2021. The articles were selected through a systematic search on the Clarivate analytics’ Web of Science-Core Collection™ online platform and were catalogued into a web-GIS, which was specifically designed to show different types of information. After a general analysis of the database, for each article were identified the bibliometric information (e.g., author(s), title, publication year), the relevant topic/sub-topic category(s) and the addressed earthquake(s). The analysis allowed to infer general information and statistics on EQTLs (e.g., relevant methodological approaches over time and in relation to the scale of investigation, most-studied events), which can be useful to get a spatial distribution of the articles and a general overview of the topic.

“…There is no doubt that the occurrence of a significant number of faults and regional ruptures/fractures in the Weihe Basin (Figure 1; Cheng et al (2018)) is intrinsically linked to regional tectonic activity (Rao et al, 2014;Lin et al, 2015). Although the earthquake catalog and records reveal the Weihe Basin as an earthquake active area (Lv et al, 2014;10.3389/feart.202410.3389/feart. .1287450 Rao et al, 2014Qu et al, 2018;Huang et al, 2022), insufficient research exists regarding the establishment of a robust correlation between tectonic activity and geothermal resources in the Weihe Basin.…”

The Weihe Basin, located in central China, stands out for its significant earthquake activity while concurrently harboring promising geothermal reservoirs. The potential association between these two geological occurrences and the underlying mechanisms remain enigmatic. Here, we compile a catalog of historic earthquakes, total strain data, data related to crustal mantle structure, surface heat flow data, and heat production data of the rocks in the Weihe Basin. Our aim is to unveil the intricate interplay among the occurrence of earthquakes, tectonic activity, and the genesis of geothermal resources. Our findings reveal that earthquake activity in the Weihe Basin is regulated by the responses of faults or fractures intricately influenced by regional tectonics. These tectonic processes are responsible for the formation of favorable geothermal resources beneath the basin. We propose there is a weak zone beneath the basin, which is controlled by a combination of tectonic processes and the flow of the asthenosphere. We finally establish a comprehensive model to visualize the genesis of the occurrence of earthquakes and the formation of geothermal resources. These results have important guiding significance for future research endeavors in the realms of both geothermal exploration and earthquake investigations within the Weihe Basin.
