Optimizing roof control using probabilistic techniques in roof failure prediction
… to the type of roof support, support density, geology, structural discontinuities, location in the mine, and elapsed time between mining and the roof fall. Using a Roof Rating System (RRS) developed for this research, a numerical rating can be given to each area of roof. Using this rating, …

Extensional evolution of the central East Greenland Caledonides
… regional and local questions in East Greenland geology. Structural, U-Pb and ⁴⁰Ar/³⁹Ar geochronologic, petrographic and thermobarometric data were combined to constrain and reconstruct a portion of the tectonic history of this orogen. Most extension was accommodated along a system of …

Test of a method for recognizing unmapped seismogenic faults.
Using the seismo-lineament analysis method developed by Cronin (Gammill and others, 2004), I have attempted to locate Holocene faults in the Point Dume 7.5 minute quadrangle of the central Santa Monica Mountains, southern California. I projected the nodal planes from each of eight focal-mechanism …

Geomorphic analyses of young faulting and fault behavior in central Nevada.
This dissertation research assesses the behavior of young faults in central Nevada through analyses of landforms associated with these faults. Four large earthquakes have occurred since 1915 in a striking N-S belt in central Nevada; no comparable earthquakes have occurred elsewhere in the Great …

Linking onshore and offshore data to find seismogenic faults along the Eastern Malibu coastline.
The Santa Monica Mountains form part of the structurally active southern edge of the Transverse Ranges Province. The purpose of this research is to identify and characterize potentially seismogenic faults in onshore and offshore portions of the Topanga 7.5' Quadrangle using near-shore geophysical …
