US Winter Storm: Deep Freeze Sparks ‘Frost Quakes’ and Mysterious Booms in Kentucky, Tennessee
A significant winter storm has recently impacted the US Northeast, resulting in severe freezing conditions. This cold spell has triggered frost quakes, also known as cryoseisms, along with mysterious booming sounds. Residents in various states have reported hearing unsettling cracking noises from the ground, raising concerns about potential damage to their homes.
The Phenomenon of Frost Quakes
Frost quakes occur when moisture just beneath the ground’s surface freezes and expands rapidly due to plunging temperatures. This sudden change causes the soil and bedrock to crack, generating vibrations that can be mistaken for earthquakes. The accompanying loud booms further contribute to the confusion about their nature.
Regions Affected by Frost Quakes
- Tennessee
- Kentucky
- Michigan
- New York
During the recent winter storm, notable reports of frost quakes emerged from Tennessee and south-central Kentucky. In Nashville, the region experienced nearly two inches of rain before rapidly dropping temperatures caused the underground moisture to freeze, leading to the phenomenon. Warnings for frost quakes were also issued for New York and Michigan, where extreme conditions saw wind chills plummet to -45 degrees Fahrenheit.
Sound and Timing of Frost Quakes
The acoustic signature of frost quakes can vary significantly. Individuals might hear sounds resembling a dull thud, a distant rumble, or even a loud crack akin to a gunshot. These occurrences typically manifest during the coldest hours of the night, mainly between 11 PM and 3 AM, when conditions are right for the expansion of frozen moisture.
Potential Damage and Safety Concerns
While frost quakes are rarely destructive, they can lead to minor damages, such as small cracks in pavements or building foundations. Residents are generally advised not to panic when hearing these sounds, as significant structural damage is infrequent.
Impact of the Winter Storm
The winter storm has had dire consequences beyond just unusual seismic activities. Reports indicate that at least 30 fatalities have occurred in the US due to the severe weather. Many victims succumbed to hypothermia after being exposed to the harsh cold. Additionally, several weather-related accidents involving traffic and winter sports have resulted in more fatalities.
The current winter storm serves as a reminder of the power of severe winter weather. Communities are encouraged to remain vigilant as conditions evolve while ensuring their safety and preparedness against the elements.
