A catastrophic tailings dam failure occurred at the Jagersfontein diamond mine in South Africa early Sunday morning, September 11, 2022, leaving at least 4 people dead and causing severe environmental damage.
Satellite imagery acquired by the Sentinel-2 satellite on September 11 shows the aftermath of the event. Unfortunately, toxic waste has also entered the nearby dam and Prosesspruit stream.1
“It appears that the pond, which is about 1 km [0.6 miles] long and 500 m [0.3 miles] wide has largely emptied,” landslides expert Dr. Dave Petley said after examining Planet Labs satellite imagery.
“The plume of tailings extends about 8.5 km [5.3 miles] towards the southeast and is up to about 1.5 km [1 miles] wide.
“Worryingly, the satellite images also indicate that the tailings have entered the main channel. The main channel flows out towards the north, with a small dam creating a lake.”
Images acquired also show that the dam has been overcome, although it is possible that it has retained a substantial volume of waste, Petley said. “We will need to wait for better imagery to understand the impact better.”
