EVER heard of a tree exploding in the cold? No? You’re not alone.
Many people online have been speculating about trees suddenly “exploding,” especially recently, as the United States faced a massive winter storm.
So, is it actually true that trees explode in freezing temperatures?
Verdict:
False
What people often describe as “exploding trees” is actually a loud popping or cracking sound, which many mistake for an explosion. Scientifically, this is called a “frost crack,” and it commonly happens when temperatures drop rapidly.
Here’s how it works: During a sudden cold snap, the sap and water inside a tree’s trunk freeze and expand. If this expansion happens too quickly for the tree's rigid bark to handle, the wood can split with a loud crack—the sound people often interpret as an explosion.
If you’re worried about exploding trees while travelling to colder countries, there’s no need to panic. These frost cracks aren't dangerous to humans. However, you should still be cautious of icicles and accumulated ice on branches, which can fall and cause injury.
And no, if you stay in a wooden house in cold weather, it will not “explode.” There’s no living sap or water left in the construction lumber to expand and cause such a crack.
