That is an MSE wall (mechanically stabilized earth) with a veneer of segmental blocks pinned to the face. The blocks are not structural per se.

Edit: Here are some photographs of what looks like a similar failure.

Edit: Actually my link is a different system.

MTNClimber - I agree that it's common, and I like that system you linked to. I would be on board with that. But in this application it looks like they used a large corrugated plastic pipe rather than a well thought out and properly designed system to work with the geotextiles.

Maybe I'm wrong and there's something out of view that helps to hold it together and give it sufficient strength.

Zoom in on LittleInch's photos and you'll see a toe attached to the corrugated pipe. I'm not familiar with the product used at this site but it seems like it functions similarly. Tough to tell from video stills.
