One person was confirmed dead, many were injured, and houses and cars were swept away while hundreds were left homeless after the mine's dam wall burst on Sunday morning, sending a torrent of mud into the Free State town.

SANSA says it is analysing the satellite data to map the extent of damage to property and infrastructure in flood-affected areas.

The enormity of the disaster can be seen in the satellite footage which shows tons of mud cutting a path of destruction through the eastern and southern sides of Jagersfontein.

SANSA says the environment was also damaged, affecting the biodiversity and ecosystem along the path of the flooding water.
