A major fly ash failure and release at Singrauli in India – Planet Labs images
On 10 April 2020 a major collapse occurred of a fly ash retaining structure at Singrauli in Madhya Pradesh in India. The South Asia Network on Dams, Rivers and People (SANDRA) has a detailed article on this collapse, which occurred in a storage pond for the Sasan Ultra Mega Power Project near to the village of Harrahva in Singrauli district. The collapse and subsequent debris flow killed six people and inundated fields for a distance of about 5 km downstream.
The site of the breach is 23.95, 82.22 – there is good Google Earth imagery of the site. This is a Planet Labs image showing the site on 9 April 2020, the day before the fly ash failure:-
Whilst this is the image from 12 April 2020, showing the breach and the release of the fly ash, and the inundated area downstream:-
Interestingly, this appears to be a comparatively new fly ash storage facility. Google Earth imagery from September 2018 does not show any storage at this particular location.
First in August 2019, there was breach in artificial pond of Essar Power Company and then in October 2019 a similar incident had taken place in Vindhyachal super thermal power plant owned by NTPC in the district. Both the incidents had caused wide scale destruction.
Back in 2009, when this blog was still on its old site, I posted about a major fly ash failure in Tennessee. That post is still visible, albeit with slightly odd formatting.
