More than half of the structures in the contiguous United States are exposed to potentially devastating natural hazards -- such as floods, tornadoes and wildfires -- according to a new study in the AG...
OESbathy version 1.0:a method for reconstructing ocean bathymetry with generalized continental shelf-slope-rise structures
OESbathy version 1.0 ocean bathymetry continental shelf-slope-rise structures
2015/9/10
We present a method for reconstructing global ocean bathymetry that combines a standard plate cooling model for the oceanic lithosphere based on the age of the oceanic crust, global oceanic sediment t...
Analysis of enigmatic structures on Mars and Venus and implications for crustal history
The earth's crust planets utopia plain terrain Mars crater wrinkles ridge
2014/10/22
The crustal history of two structurally complex areas on two different planetary bodies is explored, using a combination of image and topographic analysis, kinematic mapping and numerical modeling. Th...
Application of Electrical Resistivity and Chargeability Data on a GIS Platform in Delineating Auriferous Structures in a Deeply Weathered Lateritic Terrain, Eastern Cameroon
Gold Exploration Tropical Settings Deep Weathering
2013/3/11
Exploration for primary gold in tropical settings is often problematic because of deep weathering and the development of a thick soil cover. In this paper we present the results of both chargeability ...

Gravimetry Bouguer Anomaly Upward Continuations Gradient Structure Northern Tunisia
2013/3/11
Gravity data associated with surface geology in the Northern Tunisian Atlas offer better understand to the underlying structures in Teboursouk area and to highlight other deep or unknown structures in...
Seismicity and Geologic Structures Indubitable in Wadi Hagul, North Eastern Desert, Egypt
Eastern Desert Wadi Hagul Remote Sensing GIS Seismic Activity
2013/3/6
Paleo and recent earthquakes have been recorded in Wadi Hagul area and its environs, which have left behind geologic structures of deformation preserved in exposed sedimentary rocks. To evaluate such ...
Blending Rudists with Technology; Non-destructive Examination of the Internal and External Structures of Rudists Using High Quality Scanning and Digital Imagery
External Structures Rudists Digital Imagery
2010/12/20
Certain formations within the Cretaceous of Texas include zones of silicified rudists. Such diagenetic alteration, combined with the timing of alteration, has preserved many structural features of the...
The Analysis of Accelerograms for the Earthquake Resistant Design of Structures
Seismic Design Bracketed Duration Peak Ground Acceleration (PGA)
2013/3/6
In this paper, the analysis of ground motions (displacements, velocities and accelerations) has been performed focused to the seismic design. The relationships between the peak ground acceleration (PG...
