Hundreds of firefighters and six water bombers are fighting the main blaze, called the Sampson Flat fire, which is to the northeast of Adelaide and authorities have warned poses a threat to life.
The CFS, South Australia’s rural fire service, has been releasing maps of the burnt area since it started yesterday which, in sequence, show how quickly the bushfire has grown in less than 24 hours. The first map from late on Friday showed it at just under 700 hectares but in the last map, released around lunchtime today, it covered almost 10,000 hectares with a 126km perimeter.
Below are the maps in sequence. The times are when the maps were released, local time.
1. 6pm Friday. The perimeter is 12km and 694 hectares have been burnt. For reference, two points on the map are circled – the town of Kersbrook and a cluster of farms marked on Shillabeer Road.
