The jarring frost quakes have people around New England asking, “What was that?”.
Sandra, from Framingham, began to search her attic after she heard a series of loud thuds that woke her up through the night.
She said “It sounded like somebody dropped a wrecking ball on my roof”. This happened 3 or 4 times during the night.
NewsCenter 5 Facebook page reported more than 1000 people posted hearing similar noises. They were happy to hear there was an explanation of where the sounds were coming from.
The noises are called thermal expansion and contractions. Components in the home are shrinking and expanding with the extreme temperature changes, especially the sub-zero temperatures we have experienced this Winter.
Professor Garrick Goldenberg of Wentworth Institute of Technology explains “There’s motion because the outside temperature is different from the temperature inside of your house, so these differentials could cause movement in a different direction and could create that noise.
When materials are held together with tightly secured nails or fasteners, the pressure could become too great. That’s when the energy may be released suddenly and cause a loud noise.
This, however, is not necessarily a sign of danger. A well built house should be able to handle this.
If there are any new cracks, settlement or falling debris you should seek expert advice.
Otherwise, the noises should subside when the weather becomes warmer.
