Queensland floods from space

Ben Domensino, Monday February 11, 2019 - 17:07 EDT

Queensland's flooding has been captured in spectacular detail by high resolution images taken from space by NASA's Terra satellite.

A fortnight of monsoonal rain has left masses of water flowing through bulging river systems in northern and western Queensland this week.

The brown floodwaters in the naturally shaded image above can be seen more clearly when different colours are assigned to the various wavelengths of light that are being detected by NASA's satellite.

A third version of this false coloured image helps the inland flooding stand out even more.

A closer look at northwest Queensland shows extensive flood between the Flinders and Norman Rivers. There are visible streaks of muddy water where these rivers discharge into the Gulf of Carpentaria.

Further south, floodwaters are travelling inland through the Georgina, Diamantina and Cooper Catchments. These rivers eventually flow into the Lake Eyre Basin, however they may dry up before getting that far.

Record-breaking also caused major flooding in Queensland's eastern tropics during the last fortnight. On Sunday, sediment-laden water could still be seen flowing out to sea near Townsville.
