This is the stunning 'apocalyptic glow' that has formed over California as authorities battle a wildfire the size of Singapore.
It was filmed in the coastal city of Morro Bay and shows a smoky glow in the skies over the state, which is enduring the fifth biggest fire in its history.
The blaze, which has been named the Thomas Fire, has now burned an area of more than 230,000 acres around 100 miles northwest of Los Angeles .
