![]() ![]() Olsen had a Fond du Lac Sheriff's deputy come out and take a look at the crack, and that deputy felt like there was no danger to anyone. In my 47 years I never heard of a frost quake before," Blankenberg said. I figured it was a frost break," Olsen said.įrost or ice quakes, as they're known, most likely created the booms and left the crack in the driveway as the earth quickly expanded and contracted with the change in temperatures. Nearly a week later, the crack has pockets 9.5 inches deep. Well, I measured it out and it goes 154 feet," Olsen said. The more that we looked here it find it goes north and south. "We measured it, it went down 8 inches. The first crack was crossways in the driveway, east and west. Olsen checked around but found nothing - thinking it maybe was from the nearby gravel pit - but his grandson did find something: a crack in the middle of the driveway that hadn't been there before. It seemed like it shook the house somewhat. "I heard what sounded like two huge gunshots and I actually sat up straight," Blankenberg said. We heard a BOOM - pretty loud," Dennis Olsen said. I didn't know if it was outside," Jackie Blankenberg said. Last Tuesday night, many in Waupun felt something, after hearing something that was very loud and unexpected. WAUPUN (WITI) - The extreme cold we saw last week and thaw we've seen this week has caused its share of problems in southeastern Wisconsin - but in Waupun - they're really feeling the weather changes quite literally! ![]() They can occur over several hours or even several days.Waupun man dealing with aftermath of frost/ice quake Have the app?

This is because snow acts as an insulator when it is deep enough. This change cracks the ground, including rock, around the solid ice formation.Īn abundance of snow will prevent frost quakes from occurring. When the temperature drops rapidly, within approximately 12 to 48 hours, water that has collected below the surface of the ground freezes solid and expands quickly. When temperatures are at the freezing point, water located deep underground can begin to freeze. The severity of the cracking of the soil depends on the amount of water present. The precipitation can be in the form of rain, sleet or a mixture of wet weather conditions that have saturated the ground saturated deep down. ![]() This happens most frequently in areas where there has been a great deal of precipitation in a relatively short period. "Within the U.S., they happen most often across the central and northern Plains into the Northeast, but any place that can have saturated ground and rapid freeze cycles could experience them," Douty said.įor a frost quake to occur, there must be sufficient water present, and this water must be located deep within the ground. ![]()
