Studies have shown that the majority of global population are migrating from rural to urban areas. People leaving areas due poor services such as broadband service. Fibre optic technology has been introduced a solution quality. However, result peculiar characteristics South Africa's areas, telecommunication operators hesitant invest in ICT because it tends be much less profitable. Hence, study ...

Paleoseismological trenching was performed along the Düzce fault providing some preliminary insight about its seismogenic behavior. Dating based on radiocarbon analysis of peat samples collected from trenches and suggested seven earthquakes have occurred since 1740 BC. Integrating date constraints events exposed in suggests a periodical earthquake recurrence model. According to linear sequentia...

The geomorphic expression of active faulting and distinction paleoseismic events in areas that are rapidly obscured by erosion/sedimentation still remains a considerable scientific problem. present article discusses the revealing surface ruptures their parameters to identify capable faults without trenching estimate magnitude earthquakes. case study was at Cape Rytyi, located Baikal-Lena Nature...

The application of Ground Penetrating Radar (GPR) prospecting to the search fossil structures, particularly using advanced techniques like Finite-difference time-domain (FDTD) modelling and GPR attribute analysis, is currently poorly exploited in paleontology. Here, we promote use such a workflow at Bargiano (Umbria, central Italy), unique paleontological site known for discovery cetacean skele...

The 2019-11-1, Mw4.9 Le Teil earthquake occurred within the NE termination of Cévennes faults system (CFS) in southern France, along La Rouvière fault (LRF), an Oligocene normal which was not known to be potentially active. This shallow moderate magnitude reversefaulting event produced a 5 km-long surface rupture and strong ground shaking. No evidence previous quaternary activity observed morph...

vegetation is known to increase hillslope stability by reinforcing soil shear resistance. this reinforcement depends on the density and tensile strength of the root systems. this paper presents the results of research carried out in order to evaluate the biotechnical characteristics of the root system of parrotia persica. the profile trenching methods was used to obtaining root area ratio (rar)...
