A moletrack is a descriptive term for how strike slip faults often look when seen at the surface.]]> http://gallery.usgs.gov/photos/n63Uly8LKf_1 <![CDATA[This picture is on the far east end of the rupture. The fault went directly through the school - the chalkboard reads something like: "We're all happy because school is out".]]> http://gallery.usgs.gov/photos/n63Uly8LKf_2 <![CDATA[Izmit moletrack is near the town of Izmit.]]> http://gallery.usgs.gov/photos/n63Uly8LKf_3 <![CDATA[This is where 6 large apartments buildings all were completely flattened. Luckily they were uninhabitated. Residents were supposed to have moved in during June, but were delayed. The fault is seen in the foreground. Aykut Barka has a photo taken of this area from a helicopter.]]> http://gallery.usgs.gov/photos/n63Uly8LKf_4 <![CDATA[This shows another well expressed moletrack and marshy area around a sag pond. Sag ponds are another common feature in strike slip fault zones which occur where the fault is not straight.]]> http://gallery.usgs.gov/photos/n63Uly8LKf_5 <![CDATA[This is actually the northern strand of a 100-m-wide graben. A graben is an area bounded by multiple faults that has dropped down.]]> http://gallery.usgs.gov/photos/n63Uly8LKf_6 <![CDATA[This is adjacent to Izmit Bay where the fault leaves the Bay on its eastern side. There is a local slope down to the Bay that allowed slumping along the cracks to form the small scarps apparent.]]> http://gallery.usgs.gov/photos/n63Uly8LKf_7 <![CDATA[0.9 m high scarp with lateral offset of 1.9 m. Local changes in fault geometry are believed to have caused the vertical component across fault.]]> http://gallery.usgs.gov/photos/n63Uly8LKf_8 <![CDATA[This barn is faulted through the middle; the moletrack is seen in the foreground with the viewer standing on the fault. From the air one can see metal roof panels of the barn that rotated as the barn was faulted.]]> http://gallery.usgs.gov/photos/n63Uly8LKf_9 <![CDATA[Topographic humps offset by the fault reveal stratigraphy. Bridge in background was knocked down during earthquake.]]> http://gallery.usgs.gov/photos/n63Uly8LKf_10 <![CDATA[The fault is clearly expressed through this pasture at N40 41.959', E030 30.196'. Offset of a small road is 2.4 m (a maximum).]]> http://gallery.usgs.gov/photos/n63Uly8LKf_11 <![CDATA[A dike is offset 2.3 m.]]> http://gallery.usgs.gov/photos/n63Uly8LKf_12 <![CDATA[Moletrack showing well-expressed extensional and compressional components of the rupture.]]> http://gallery.usgs.gov/photos/n63Uly8LKf_13 <![CDATA[A close-up shot of a tree that was actually split into two by faulting. The tree records 0.8 m of offset, a larger view reveals that across the entire fault zone, offset is 3 m.]]> http://gallery.usgs.gov/photos/n63Uly8LKf_14 <![CDATA[The offset stream bank of the Sakarya River. The tree lines record an offset of 3.3 m.]]> http://gallery.usgs.gov/photos/n63Uly8LKf_15 <![CDATA[The fault trends through a highway overpass (which did not fail), causing the guardrail to be offset ~2.8 m.]]> http://gallery.usgs.gov/photos/n63Uly8LKf_16 <![CDATA[A man walks alongside the rubble of a destroyed building.]]> http://gallery.usgs.gov/photos/lQGs38Vji1_0 <![CDATA[Structural damage in the earthquake region.]]> http://gallery.usgs.gov/photos/lQGs38Vji1_1 <![CDATA[A view of a few damaged buildings in the earthquake region.]]> http://gallery.usgs.gov/photos/lQGs38Vji1_2 <![CDATA[A collapsed building in the earthquake region.]]> http://gallery.usgs.gov/photos/lQGs38Vji1_3 <![CDATA[A collapsed building in the earthquake region.]]> http://gallery.usgs.gov/photos/lQGs38Vji1_4 <![CDATA[Structural damage in the earthquake region.]]> http://gallery.usgs.gov/photos/lQGs38Vji1_5 <![CDATA[A man stands next to a damaged building.]]> http://gallery.usgs.gov/photos/lQGs38Vji1_6 <![CDATA[Structural damage in the earthquake region.]]> http://gallery.usgs.gov/photos/lQGs38Vji1_7
