Quantifying Natural Fault Geometry : Statistics of Splay Fault Angles
We propose a new approach to quantifying fault system geometry, using an objective fit of the fault geometry to a test function, specifically here a fault branch. Fitting a “Y” shaped object using a cost function to dextral faults in California, we find a number of significant results arising from using a systematic, objective, quantitative approach. (1) The largest angle of the branch structur...
متن کاملThree-dimensional splay fault geometry and implications for tsunami generation.
Megasplay faults, very long thrust faults that rise from the subduction plate boundary megathrust and intersect the sea floor at the landward edge of the accretionary prism, are thought to play a role in tsunami genesis. We imaged a megasplay thrust system along the Nankai Trough in three dimensions, which allowed us to map the splay fault geometry and its lateral continuity. The megasplay is c...

متن کاملFloods and tsunamis.
Floods and tsunamis cause few severe injuries, but those injuries can overwhelm local areas, depending on the magnitude of the disaster. Most injuries are extremity fractures, lacerations, and sprains. Because of the mechanism of soft tissue and bone injuries, infection is a significant risk. Aspiration pneumonias are also associated with tsunamis. Appropriate precautionary interventions preven...
متن کاملFrictional and hydrologic properties of a major splay fault system, Nankai subduction zone
[1] We report on laboratory experiments examining the frictional and hydrologic properties of fault gouge and wall rock along a borehole transect that crosses a major out-of-sequence thrust splay fault within the Nankai accretionary complex. At 25 MPa effective normal stress, the fault zone material is frictionally weak (m 0.44) and exhibits low permeability after shearing (k < 5.5 10 20 m). Fa...
