Deformed soft-sediment deformation structures (SSDS) can indicate polyphase deformation events and provide valuable insights into the inversion process of a basin. Herein, we present the Miocene–Quaternary deformation inversion history of the Bomun sub-basin in the Gyeongju area of SE Korea. The inferred ENE compression direction (σHmax) based on p...

High-level radioactive waste should be isolated from humans and society for over 100,000 years. Several factors should be considered for a geologically stable disposal site such as topography, faults, seismic activity, and hydrological properties. Brittle structures within the bedrock, such as faults, act as potential flow pathways for radioactive...

On 26th May 2021, an earthquake with a moment magnitude Mw 5.1 hit the densely populated cities of Gisenyi (Rwanda) and Goma (D.R. Congo) which sit on the active East African Rift System. It was one of the largest earthquakes associated with the 2021 Mount Nyiragongo eruption. Although of moderate magnitude, the earthquake substantially damaged man...

The morphological characteristics and distribution of volcanic cones of Jeju Island in Korea could be controlled by several factors, including stress field in the substrate and subsurface fractures. Controlling fractures, however, might not be visible on the outcrop volcanically active areas like Jeju Island, because of the layer of volcanic rocks...

Layer-parallel shearing has been reported along the Taebaek-type Joseon Supergroup, which is distributed between the Okdong Fault and the Gakdong Thrust, which are the major tectonic lines along the Okcheon Belt. We conducted a study to understand the kinematics of these structures. We identified several shear indicators through field surveys in th...

Among the world’s lakes, Lake Kivu, a rift lake in the western branch of the Eastern African Rift System, has significant reserves of dissolved chemicals. However, no research has been done on their vertical variation in lake and how they affect the environment. This proposed chapter will review earlier research to better understand the origin of L...

Late Cretaceous granitic intrusions are common in the southeastern Korean Peninsula. Most of these intrusions enclose abundant microgranular enclaves (MEs) and dikes of almost identical age to their plutons. The granitic intrusion in the Taejongdae area encloses a distinct type of enclave known as zoned MEs. The zoned MEs in this region are compose...
Article
Structural inversion refers to the reverse reactivation of extensional faults that influence basin shortening accommodated by contractional faults or folds. On the Korean peninsula, Miocene inversion structures have been found, but the Cretaceous rocks on Geoje Island may have undergone inversion as early as the Upper Cretaceous. To evaluate the st...

Article
Full-text available
Geomorphic indices have been used to assess relative tectonic activity, quantify surface relief and identify geomorphic anomalies caused by blind fault and/or fold. These indices, especially related with drainage system and mountain front, can be easily recognized through aerial photo as well as high-resolution DEM. The tectonic activity even over...

The Yeonghae basin is located at the northeastern part of the Yangsan fault (YSF; a potentially active fault). The study of the architecture of the Yeonghae basin is important to understand the activity of the Yangsan fault system (YSFS) as well as the basin formation mechanism and the activity of the YSFS. For this study, Digital Elevation Model (...

According to the records of historical and instrumental earthquakes, the southeastern part of the Korean Peninsula is considered the highest seismic activity area. Owing to recent reports of numerous Quaternary faults along the Yangsan and Ulsan fault zones, paleoseismological studies are being actively conducted in these areas. The study area is l...
Article
The cross-cutting of Riedel fractures in brittle strike-slip shear zones creates fault blocks. Open spaces develop between the blocks as they rotate due to increased shear deformation. The present research focuses on extending open spaces vary from one shear zone to others depending on the dip direction of the sub-fractures and the structural style...

Abstract Lineament analysis is one of the crucial approaches intensively used in structural geology. It provides significant information about the main structures of the area under study for a wide range of applications. Many remote sensing methods such as aerial photos, LiDAR and DEM have been used to extract lineaments. South Korea is characteri...

Based on historical earthquakes and paleoseismical data, the Ulsan fault zone has a higher potential of large earthquakes in Korea. Thus, it is very important to understand the paleoseismic characteristics of the Ulsan fault in order to reduce future earthquake hazards. The NNW-trending Ulsan fault has been known as a reverse dominant fault. Howeve...

Fold axis of fold, a representative ductile deformation structure, is important for collecting information on the 3D fold structure and the orientation of maximum horizontal principal stress at the time of deformation. For this reason, several fold axis measurement methods based on the fold-related structural elements have been suggested and used e...

Deriving paleoseismological fault parameters of active faults is essential for earthquake disaster provision. The purpose of this study is to document the fault characteristics of Wonwonsa fault, which was recently reported in the 2nd fault outcrop on the eastern side of the Ulsan fault, and to provide fault parameters, such as the timing of activi...

The earthquake environmental effects (EEEs) around the epicentral area of the Pohang earthquake (Mw-5.4) that occurred on 15 November 2017 have been collected and classified using the Environmental Seismic Intensity Scale (ESI-07 scale) proposed by the International Union for Quaternary Research (INQUA) focus group. The shallow-focus 15 November Po...

The complex geometry and tectonic evolution of the Saharan-Tunisian Southern Atlas strike-slip fault systems, North Africa, have not been investigated comprehensively to date. This paper proposes new conceptual models to better understand the structural styles along these intraplate fault zones. We use a multidisciplinary approach including field o...

Kinematic and sedimentological analyses of pull-apart basins are important to reconstruct the tectonic evolution of a pull-apart basin. The Yeonghae depression has been interpreted as a pull-apart basin developed in the stepover zone between the Yangsan and Yeongdeok faults. The reconstruction of the tectonic evolution of the Yeonghae basin is impo...
