Phivolcs has recommended avoiding construction within 5 meters on each side of a
fault trace, or a 10-meter wide 'no-build zone.'
Near the Chaman
Fault trace, these fold and faults appear to align at an angle setting up an en-echelon pattern which is a common feature of strike-slip faulting.
The trenches were dug perpendicular to the
fault trace, with a length between 8 and 70 m, reaching 5 m of maximum depth.
The
fault trace comprising a series of parallel splays is exposed over a length of approximately 7 km and is positioned along the edge of a Carboniferous basin in proximity to the Eastern Highlands Shear Zone (EHSZ) of Barr and Raeside (1989).
The challenging 45-degree angle at which the pipes cross the
fault trace would result in the pipelines experiencing compression and rotation forces during fault movement.
Where discontinuities are well defined, the position of the
fault trace may be highly evident on the record sections event to someone entirely inexperienced in seismic interpretation.
There are two abandoned quarries in the Upper Cretaceous limestone situated exactly at the
fault trace. The lower one has been abandoned for more than 15 years and will remain closed.
The expression of the Thelichi fault is complicated by a line of Aeolian sans coincident with the
fault trace. Nath (2004); Takashi et al., (1991).
"It's very surprising how clearly you can see the
fault trace as it cuts up glaciers," says Peter J.
Jeffrey Perez, Phivolcs supervising science research specialist, explained that a remapping was conducted from 2011 to 2012 to fill the gaps in the
fault trace.
