For the past week we have been witnessing the devastation and destruction of the two major earthquakes that hit southeastern Turkey. Like many of you, the people of that region have been much in our prayers. The pictures of collapsed and partially collapsed buildings, and a stream of statistics, tell of the tremendous loss of life due to this event—and now in the aftermath the grief and suffering of the survivors.
In the description of earthquake, geologists say that it was the movements of the Anatolian and Arabian Plates that caused all of this devastation. They have called this event a “slip strike displacement” of the plates. This caught my attention for I remember reading in Denis Baly’ classic, The Geography of the Bible, that some experts believe that, in part, this was how a portion of the Great Rift Valley was formed—that is, Cisjordan and Transjordan have moved past each other (basically north-south) some 67 miles! (Baly, p. 23). That is, if you would shift Transjordan south about 67 miles, some of its faulting and rock formations would match their counterparts in the Judean Hill Country.
Coming back to Turkey, I wondered what a “slip-strike tectonic movement” might look like on the ground. I recently came across the photos of OzdemirAlpay @geodesist_a of a road in the Turkish village of Hasss, which is located about 45 mi. north northeast of Antakya, that caught my attention and I thought I would share them on this blog.
In this seemingly serene setting, notice how the road has been displaced about 6-8 feet in a horizontal direction! A slip-strike fault.
This is the same area, but notice the “crack” in the ground! Is this (near) where the two plates meet? It seems so pastoral, but we know how powerful the forces of this movement were!!
Notice the horizontal displacement of the “center line” of the road! A slip-strike fisure.
We continue to pray for the people of Turkey!

Very helpful! I always appreciated Denis Baly’s book. Thanks for the pictures which illustrate this slip-strike phenomena.
