Morphotectonic is one of the new reconition methods of tectonic movements and earthquakes knowledge. Study and measurement of landscapes and forms which made by active tectonics are important objects in morphology science. Active tectonic movements have recorded in the morphology of rivers, drainages, alluvial fans and mountain fronts in a region. Research area is located between 55° 30' -57° 0...
High resolution DEMs obtained from LiDAR topographic data have led to 9 improved landform inventories (e.g. landslides and fault scarps) and understanding of 10 geomorphic event frequency. Here we use airborne LiDAR mapping to investigate 11 meltwater pathways associated with the Tweed Valley palaeo ice-stream (UK). In particular 12 we focus on a gorge downstream of Palaeolake Milfield, previou...
Using state-of-the-art computational tools in seismology and structural engineering, validated using data from the Mw=6.7 January 1994 Northridge earthquake, we determine the damage to two 18-story steel moment-frame buildings, one existing and one new, located in southern California due to ground motions from two hypothetical magnitude 7.9 earthquakes on the San Andreas Fault. The new building...
The Tiber valley is a prominent feature in the landscape of ancient Rome and an important element for understanding its urban development. However, little is known about the city's original setting. Our research provides new data on the Holocene sedimentary history and human-environment interactions in the Forum Boarium, the location of the earliest harbor of the city. Since the Last Glacial Ma...
The Mw 7.8 earthquake jolted the central region of Nepal on April 25, 2015, and caused gigantic destruction. Satellite remote sensing is an effective tool to grasp damages in a wide area. In this study, preand post-event ALOS-2 satellite SAR data were used to detect affected areas in Kathmandu, the capital city of Nepal. Firstly, the crustal movements around the Kathmandu Valley were estimated ...
Several properties within the eastern Eyre Mountains are currently undergoing tenure revue. This report provides geological information relevant to these reviews, particularly on the sequence of glacial deposits south from Kingston. The geology of the Eyre Mountains is dominated by low-grade metasedimentary rocks of the Permian Caples terrane, becoming increasingly schistose toward the northeas...
[1] We model Pn waveforms from two earthquakes in the southwestern United States (Mammoth Lakes, California, and western Nevada) to determine a velocity model of the crustal and mantle structure beneath the southern Sierra Nevada and Walker Lane. We derive a one-dimensional velocity model that includes a smooth crust-mantle transition east of Death Valley and extending south into the eastern Mo...
Soil samples were collected from six different locations in Araba valley, situated between Aqaba port and Dead sea. The samples have been analysed by using gamma-ray spectrometry. From the measured gamma-ray spectra, activity concentrations are determined for (238)U, (232)Th and (40)K. The mean activity concentration for (238)U, (232)Th and (40)K was found to be in the range 19 +/- 1.4 to 38.7 ...
