Posted about it yesterday - The Landslide Blog has a really good writeup and some videos:
Edenville Dam failure: the astonishing video of the collapse sequence
Yesterday I posted about the remarkable and devastating failure of the Edenville Dam in Michigan on Tuesday 19 May 2020. There are now heartbreaking images online showing the damage that the resulting flood has caused downstream. Given the known weakness of the dam, this is an unacceptable situation.
From a technical perspective, the most remarkable aspect of this failure is that the sequence of events that induced the breach is caught on video. I tweeted about this yesterday, but it turns out that the landslide that initiated the collapse was also captured, by Lynn Coleman, and posted to Youtube by MLive. This video is astonishing:
Talk about right place and right time. Dave then does a good analysis of the slide - frame by frame.
This is what happens when you do not maintain your infrastructure.
