Fracture cutting across the countryside (left to right) such that the fault scarp is lit up by the sun, appearing as a bold white line.

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.

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.

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.

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.

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.

Ring of Fire
The "Ring of Fire", also called the Circum-Pacific belt, is the zone of earthquakes surrounding the Pacific Ocean- about 90% of the world's earthquakes occur there. The next most seismic region (5-6% of earthquakes) is the Alpide belt (extends from Mediterranean region, eastward through Turkey, Iran, and northern India.
