Looking towards NW across Lavic Lake, rupture passing from lower right,
stepping out toward upper left; NW end of the surface rupture is in the
distance on the far side of Lavic Lake.
|
|
Cracks on far side of wash; called 'en-echelon' breaks where they step
sideways.
|
|
Splaying of fractures viewed from above.
|
|
Southeast of maximum displacement site. Here we see 3-4 meters o
right-lateral slip have offset a ridge and created a 'shutter' ridge
blocking flow in the dry creek channel. The white vertical surface is the
fault scarp.
|
|
Fractures crossing a wash.
|
|
view right along the main rupture zone, and also visible is a subsidiary
fracture from lower right corner coalescing with the main break in the middl
distance.
|
|
View downward onto vehicle tracks crossing the fault at a high angle.
One can see 2.5 to 3.5 meter right-lateral displacement of the tracks.
|
|
Fracture running along hillside in low-relief topography with offset
gullies and tracks.
|
|
Ground view along surface rupture, showing the fracturing
of the soil and how pieces have been pushed up within the fault zone.
|
|
Subparallel breaks coalesce on face of hill (in shadow) and form a
single rupture heading off to the upper left.
|
|
Downward view onto gullies, gravel bar, and other laterally
offset features. Here slip appears to be about 2 meters.
|
|
Rupture cutting across the countryside in loose alluvium.
|
|
Breaks cutting alluvium, nicely lit.
|
|
View downward onto site with maximum observed lateral
displacement along the Lavic Lake fault. Here a vehicle
track and dry creek bed are laterally offset by approx.
370-480 centimeters. The orientation of fractures here
is nearly North-South. Compression locally across the
fault pushed up a 'mole track' where the fault breaks
the dirt road at the right side of the photo.
|
|
Fracture cutting across the countryside.
|
|
Fracture cutting across the countryside (left to right) such
that fault scarp is lit up by the sun, appearing as a bold
white line.
|
|
'Mole track' at the max. slip site from the ground.
|
|
View towards south across Lavic Lake, with the surface
rupture running from lower right to upper left. In the
middle distance on the right is an ancient lava flow.
|
|
Splayed fractures running through loose alluvium.
|
|
'Apparent' vertical displacement and scarps caused by
mainly lateral slip.
|
|
Same as 21.
