Sat Jan 24 05:20:00 UTC 2026: # Experts Debunk “Exploding Trees” Myth Amidst Impending Winter Storm
The Story: As a potentially historic winter storm threatens over half of the United States, social media has been abuzz with warnings of “exploding trees.” John Seiler, a professor and tree physiology specialist at Virginia Tech, clarified that while extreme cold can indeed damage trees, the term “exploding” is a misnomer. The phenomenon, more accurately described as “frost cracks,” occurs when sap inside the tree freezes and expands, causing the bark and wood to crack, sometimes with a loud bang resembling a gunshot.
While these cracks aren’t inherently dangerous to passersby, they can leave trees vulnerable to insects, fungi, and bacteria. Experts warn that the primary danger during winter storms lies in the heavy accumulation of ice and snow, which can cause branches to fall, posing a significant risk to people and property.
Key Points:
- “Exploding trees” are actually frost cracks caused by the freezing and expansion of sap inside the tree.
- Rapid temperature drops or lack of acclimatization to cold can trigger frost cracks.
- The sound produced by a frost crack can be loud, resembling a gunshot.
- Frost cracks themselves aren’t likely to kill a tree, but can make it vulnerable to pests and diseases.
- The primary danger during winter storms is falling branches due to heavy ice and snow accumulation.
Key Takeaways:
- Social media hype can often misrepresent scientific phenomena, leading to unnecessary alarm.
- While the term “exploding trees” is sensational, the underlying issue of winter storm damage to trees is a genuine concern.
- Focus on the real risks posed by heavy ice and snow accumulation on trees, such as falling branches, is crucial for public safety.
- The impact of winter weather on trees varies depending on species and growth patterns.
