NASA satellites detected a huge fire in the Simpson Desert which appeared to have burnt through more than two million hectares. But there wasn’t any fire.

NASA satellites recorded hot spots spanning across 22,000 sq km in the state’s Far North about 2am on Friday, and it was reported through a Twitter message service for Victoria and SA incidents.

But Country Fire Services had no reports of the fire and their investigation did not find evidence of this blaze.

A CFS spokesman said their regional team and locals in the Far North had not heard of this fire.

“It is unlikely for a fire of this size and the smoke with it to go unreported, aircraft would spot it and report back — but so far we’ve heard nothing about this fire,” he said.

“It could have been salt pans reflected to the satellite.”
