Aerial Photo of the Surface Rupture
Cracks on far side of wash; called 'en-echelon' breaks where they step sideways....
Aerial Photo of the Surface Rupture
Southeast of maximum displacement site. Here we see 3-4 meters of 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....
Aerial Photo of the Surface Rupture
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 middle distance....
Aerial Photo of the Surface Rupture
View downward onto vehicle tracks crossing the fault at a high angle. One can see 2.5 to 3.5 meeter right-lateral displacement of the tracks....
Aerial Photo of the Surface Rupture
Fracture running along hillside in low-relief topography with offset gullies and tracks....
Aerial Photo of the Surface Rupture
Ground view along surface rupture, showing the fracturing of the soil and how pieces have been pushed up within the fault zone....
Aerial Photo of the Surface Rupture
Subparallel breaks coalesce on face of hill (in shadow) and form a single rupture heading off to the upper left....
Aerial Photo of the Surface Rupture
Downward view onto gullies, gravel bar, and other laterally offset features. Here slip appears to be about 2 meters.... |
