We investigated the optically stimulated luminescence (OSL) and thermoluminescence (TL) characteristics of quartz from sediments parent rocks across South America. OSL TL sensitivities were compared with characteristic dose response curves. Additionally, we estimated electron trap parameters contrasting sensitivities. Our results show that natural (initial 0.8 s) (110 °C peak) are positively co...

While there has been significant research on the dating of paleoearthquakes using methods such as surface cosmogenic dating, and trench-based luminescence or radiocarbon this paper focuses implementing an alternative method a fault scarp-based optically stimulated (OSL) approach. Hence for first time, we investigated Pleistocene to Holocene earthquake cycle Manisa Fault, one dip-slip active fau...

Abstract The quality and quantity of geochronologic data used to constrain the history major earthquakes in a region exerts first-order control on accuracy seismic hazard assessments that affect millions people. However, evaluations geochronological are limited by uncertainties related inherently complex depositional processes may vary spatially temporally. To improve confidence models earthqua...

Based on field investigation, optically stimulated luminescence (OSL) dating and sedimentary analyses, this research shows that the Yinduba paleolandslide-dammed lake (PDL) was formed by a catastrophic rock avalanche damming Jinsha River before 74 ka ago. According to blocked ancient riverbed, depth determined about 110 m corresponding length 22 km when level reached peak. Geomorphologic featur...
