Rare footage recorded and shared by Benjamin Garland on Storyful on November 15 shows a large tree in New South Wales, Australia burning bright red from the inside but the outer bark is largely unaffected. . The fire may have been smoldering for several days before a major blaze swept through the forest.

"I discovered the hollowed-out tree trunk on my way home after the fire. The fire went out the next day and only the thin outer layer of bark and wood remained," car games Garland shared.

The reason behind this strange phenomenon is still unclear, but according to a similar case recorded in Texas, USA last month, it may be related to honey fungus, a parasitic species that eats honey. The tree trunk is hollow. This causes the wood inside to burn before coming into contact with the fire.

In addition, lightning strikes can also cause trees to catch fire from the inside, according to IFL Science . The reason is because tree sap conducts electricity and heat better than wood, so when struck by lightning, it is burned to a very high temperature in a short time, causing great pressure from inside, causing the tree trunk to catch fire or even is to explode.
