The Chi-Chi earthquake (M W = 7.6) took place in central western Taiwan in 1999. The earthquake caused reactivation of the Chelungpu Fault and resulted in 100-km-long surface ruptures. The fault strikes mostly north-south to NNE-SSW;... more
Recently, a fallen Buddha statue of the late-8th century was discovered in Mt. Nam, Gyeongju, SE Korea. The Gyeongju area is located in intersection of two major young structural features in Korea: the Yangsan and Ulsan faults. According... more
The Seongsan district in the Jindo-Haenam basin of southwest Korea comprises Precambrian gneissic basement, overlain and intruded by Cretaceous volcanic (98-71 Ma) and plutonic (86-68 Ma) rocks, respectively. Haenam Formation volcanic and... more
Kinematical and fractal analyses were conducted on a fracture network in a well-exposed granite outcrop in SE Korea. The objective of this study is to examine the temporal and spatial evolution of the fracture network. From the... more
Faults and fractures are important factors that control fluid flow in rock masses in hydrothermal, groundwater, and hydrocarbon systems. In this paper we examine local variations in fluid flow as evidenced by the distribution patterns and... more
When an earthquake occurs on a fault, the rock volume around the rupture undergoes changes in stress state, which are closely related with aftershocks, displacement and damage zones. Recently, detailed data on ground ruptures and slip... more
Strike-slip faults are often accompanied by a variety of structures, particularly at their tips. The zones of additional fracturing are classified as tip-damage zones. These zones can be subdivided into several different damage patterns... more
Several strike -slip faults at Crackington Haven, UK show evidence of right-lateral movement with tip cracks and dilatational jogs, which have been reactivated by left-lateral strike -slip movement. Evidence for reactivation includes two... more
Several differently scaled strike-slip faults were examined. The faults shared many geometric features, such as secondary fractures and linkage structures (damage zones). Differences in fault style were not related to specific scale... more
Damage zones show very similar geometries across a wide range of scales and fault types, including strike-slip, normal and thrust faults. We use a geometric classification of damage zones into tip-, wall-, and linking-damage zones, based... more
Well-exposed strike-slip faults in limestones in the north-western part of Gozo show damage zones that can be grouped into three categories based on their location along faults; tip damage, linking damage and distributed damage. The... more
The relationship between maximum displacement (d max ) and fault length (L) has been studied extensively, mainly in attempts to understand how fault geometry varies over different length scales. Individual data sets are sampled over... more
The Korean peninsula is widely regarded as being located at the relatively stable eastern margin of the Asian continent. However, more than 10 Quaternary faults have recently been discovered in and reported from the southeastern part of... more
Geometric and kinematic analyses were conducted on a fault zone at a construction site in SE Korea to understand its temporal and spatial evolution. This area is tectonically characterized by the existence of reversely reactivated faults... more
Surface sediment samples from the Tiruma- lairajan river estuary were studied for grain size pattern, organic matter, and heavy metals (Fe, Mn, Zn, and Pb) using the sequential and bulk metal extractionmethods to evaluate metal behavior.... more
A study was conducted to evaluate the water quality of Kottur block, Thiruvarur district, Tamilnadu. Groundwater samples from hand pumps and tube wells of 16 stations were analyzed during postmonsoon and pre- monsoon (2008) with the help... more
The aim of this study is to understand the various sources and factors controlling the abundance and distribution of clay minerals, sand, silt, clay and organic matter of the surface sediments of Tirumalair- ajanar Estuary in two... more
