Palynological study of Tungu Buzum Hill was investigated with a view towards determining the age outcrop, compare its miospore content adjacent Buzu Valley carbonaceous shale, their stratigraphic relationship and paleoenvironment deposition litho-sequence. Field involved litho-description logging achieved by noting rock type, mineralogical composition, bed thickness, texture, sorting, roundness...

We investigated the Late Quaternary activity of a major, crustal fault affecting southern sector Central Apennines, i.e., Roveto Valley Fault (also known as Liri fault). This chain was hit by numerous M>5 historical seismic events. For some these, e.g., 1654 one (M w 6.33), causative seismogenic source has never been conclusively defined. Within this seismotectonic framework, recent is s...

Blind reverse faults are challenging to detect, and earthquake records can be elusive because deep fault slip does not break the surface along readily recognized scarps. The blind Reelfoot in New Madrid seismic zone central United States has been subject of extensive prior investigation; however, extent at southern portion remains unconstrained. In this study, we use lidar map terraces lacustri...

The Wenchuan earthquake of 12 May 2008 is the most destructive earthquake in China in the past 30 years in terms of property damage and human losses. In order to understand the earthquake process and the geo-morphological factors affecting the seismic hazard, we simulated the strong ground motion caused by the earthquake, incorporating three-dimensional (3D) earth structure, finite-fault ruptur...

Integration of geological and geophysical data is essential to elucidate the configuration geometry surface subsurface structures, as well their long-term evolution. The NNW–SSE-striking incised valley parallel mountain range in southeastern margin Korean Peninsula, extending 50 km from Gyeongju Ulsan cities, are together regarded one most prominent geographical features South Korea. This paper...

[1] The role of phyllosilicate fabrics in fault gouge is a poorly understood component of the mechanical and hydrologic behavior of brittle fault zones. We present 90 fabric intensity measurements using X-ray texture goniometry on 22 natural clay-rich fault gouges from low-angle detachment faults (Death Valley area detachments, California; Ruby Mountains, Nevada; West Salton Detachment Fault, C...
