Landslide Just Misses Viaduct Piers in Turkey

A major landslide was captured on video narrowly missing piers for a viaduct under construction at the Yusufeli Dam site in Artvin, Turkey. The slide appears to be on an engineered cut slope benched into the hillside. According to media reports, the viaduct piers were not damaged.

There is another video from earlier in the month that gives more of a perspective view of the area which appears to be the site of a former town presumably slated to be inundated as the dam is filled. The dam filling began in November of 2022. The local government has said the viaduct construction will continue as planned.

SR 87 Landslide Between Payson and Phoenix, March 2008Back in March of 2008 there was a landslide that closed SR 87 in between Phoenix, Arizona and Payson. It’s been of great interest to me since it is in my state and affected a highway. I was hoping my firm (NCS Consultants, LLC) might be asked to work on the remediation through our on-call contract but it didn’t happen. Its probably for the best, it sounds like it’s been a troublesome geotechnical engineering problem. Fast forward to last week, and the slide area was in the news again because the slope is still moving and apparently causing some additional deformation of the roadway. (Photo by ADOT)

I had heard about this a while ago through our ADOT contacts, but I make it a policy not to take advantage of my contacts through my day job for GeoPrac.net content (not without permission anyway). So I didn’t want to blog about it until it hit the mainstream media. Last week, the Arizona State Geologist blogged about the SR 87 slide moving again, as did Ken through his AEG Arizona Section blog. It was even covered on one of my favorite blogs, Dave’s Landslide Blog. I finally have a chance to wade through these blog posts and some of the reports and videos to present a summary of the situation, available information and offer my own perspective.
