While the bitter cold makes life uncomfortable above ground, it appears it is causing problems below the surface, too.
In emails and tweets to CP24, residents from various parts of the Toronto area, including York and Peel regions, Oshawa and Rexdale, said they were awakened overnight by thunderous booms that they suspect were caused by cryoseisms, also known as frost quakes, in the frozen ground.
Some viewers said the loud booms startled them and shook their houses.
Police in York and Peel regions said they received several calls from people who were alarmed and wanted to know what was going on.
Similar noises were heard earlier this week and Christmas Eve.
Frost quakes are a rare event in the GTA and they occur when ground water freezes and the ice expands, creating an explosive expansion of air, said CP24 meteorologist Bill Coulter.
In the GTA, the temperature dropped to about -23 C overnight with a wind chill of -35.
As Global Warming increases, we’re just going to have to get used to this.
-23 C ~ -9.5 F....
looks colder in C...
Anything aboot Canada, we’ll ping you, eh!
Heard about this from a buddy of mine in the Toronto area. I’d never heard of frost quakes before. Crazy stuff.
I was curious... there’s been talk of another Maunder minimum which last occurred during the last “mini ice age” in the 15th through 17th centuries. There were historical reports of glaciers as far south as Denmark in Europe. If glaciation pushes south and parts of southern Canada and the northern US started seeing widespread glaciation, would these types of events presage that?
I’m only 33 but I’ve never heard of “frost quakes.” Is it possible that temperatures will remain low enough throughout the year that parts of the US turn into permafrost?
Oddly enough, when the temp’s dip into the teens, my deck booms. It’s just outside my bedroom and wakes me up.
*As Global Warming increases, were just going to have to get used to this*
It’s the hottest year EVER!...according to the “scientists” on the two ships that are stuck in the ice.
It sounds similar to the geological phenomenon of "frost wedging", except there's no loud explosion of air. Frost wedging is what causes many rock falls.
"A form of mechanical weathering caused by the freezing of water that has entered a pore or crack in a rock. The water expands as it freezes, widening the cracks or pores and often loosening or dislodging rock fragments. As the ice forms, it attracts more water, increasing the effects of frost wedging."
Some article I read yesterday claimed GW has intensified and the last 4 years are the warmest on record.
Wonder if they’ll have any broken water and gas mains.
There may have been glaciers in “Denmark” at the height of the last Ice Age (~25,000 yrs ago), but certainly not in the 17th Century.
It took the big ice sheets about 10,000 yrs to retreat to their present locations (the poles and isolated mountain pockets), and would probably also take about that long to expand again (if conditions were cool enough).
So the continental US might see permafrost again, but not for a very long time.
Did they say where ?
Hey, from looking at it from down here in Texas, -9 looks pretty cold.
I doubt that it would be that extreme. During the Little Ice Age there was extensive agriculture around the Lower Great Lakes with the Huron, Neutral and Iroquois nations all growing corn. The last period of glaciation in this area was the Ice Age ~10,000 years ago; those glaciers created the Great Lakes and the land in Southern Ontario is still rebounding from the weight of the ice, rising a couple of centimetres per decade IIRC.
The main effect of a cooling climate around here would be colder winters and shorter summers but it would take a *huge* event, such as Yellowstone erupting, to have any chance of glaciers returning.
BTW I’m 50 and never heard about this phenomenon until last week. Temperatures this cold are unusual around Toronto; normals here for this date are high -2C, low -9C. We’re at roughly the same lattitude as Oregon.
Civvie, anything you can add or clarify on this>
Yeah, you’re the people that can’t drive on an inch of snow!
Same thing happens to roads in Northern Ontario, where it’s known as “frost heaving”. Huge repair bills every spring. Back in the 1970s they built a section of the Trans-Canada Highway in Sudbury, Ontario that doesn’t heave- the roadbed included a mix of gravel and styrofoam chunks. Don’t know what came of the experiment.
Broken water mains are routine here during colder winters, especially if temps drop below -10C.
Oh, and gas mains are not usually a problem- most of them are plastic with some flexibility.
Hard to believe the amount of pressure that builds up as a result of water freezing and expanding. I mean, if it can cause an iron pipe to burst... I wonder what the limitations are. Surely the force must have a limit. It of course would depend on various factors, such as how fast the water freezes (how cold the tempts are), length of time the freezing goes on, etc. It would be great if we could somehow use this force to create a mechanical device of sorts.
Frost heaving is clearly related to frost wedging but applies to a more specific occurrence ...
“Frost heaving (or a frost heave) results from ice forming beneath the surface of soil during freezing conditions in the atmosphere. The ice grows in the direction of heat loss (vertically toward the surface), starting at the freezing front or boundary in the soil. It requires a water supply to keep feeding the ice crystal growth; and the growing ice is restrained by overlying soil, which applies a load that limits its vertical growth and promotes the formation of a lens-shaped area of ice within the soil. Yet the force of one or more growing ice lenses is sufficient to lift a layer of soil, as much as 30 cm or more.
The soil through which water passes to feed the formation of ice lenses must be sufficiently porous to allow capillary action, yet not so porous as to break capillary continuity. Such soil is referred to as “frost susceptible.” The growth of ice lenses continually consumes the rising water at the freezing front. Differential frost heaving can crack pavementscontributing to springtime pothole formationand damage building foundations.
Needle ice is essentially frost heaving that occurs at the beginning of the freezing season, before the freezing front has penetrated very far into the soil and there is no soil overburden to lift as a frost heave.”
More likely trees freezing. They sound like guns firing , only deeper sounding , a boom rather than a crack . When I was a kid I remember the house making loud banging noises , rafters contracting in the cold.
This was definitely in the ground- the floor vibrated here and I’m three storeys up.
I think it was a link on Drudge.
They’re sticking with their story no matter how much we’re freezing arses off.
Oh, like most people, we can drive on an inch of snow. But, what we typically get is an inch of freezing rain with sleet on top of that. Ain’t no Yankee in the world going to drive on that. I once did two 360’s on an elevated causeway over Corpus Christi Bay with an uncle who told me to trust him - he drove on snow all the time back in Illnois and Ohio. Another couple feet and we would have been over the guardrail and into the icy brink.
Go to Drudge and click on “Global Warming Intensifies”
I suppose it’s time to figure out how to copy and paste with this phone
Prior to Christmas we got the freezing rain with a couple inches of snow on top - it was a mess.
Best to just stay home by the fire.

It’s what came up when I clicked on Global Warming Intensifies
We’ve been having these (they’re called cryoseisms) for the last could of weeks. A couple of them have shaken the house so hard that I thought someone had driven their car into the house.

I’m 81 and never heard of them.
THE ACQUITTAL OF CARBON DIOXIDE
by Jeffrey A. Glassman, PhD
"Carbon dioxide in the atmosphere [historically] is the product of oceanic respiration due to the well-known but under-appreciated solubility pump. Carbon dioxide rises out of warm ocean waters where it is added to the atmosphere. There it is mixed with residual and accidental CO2, and circulated, to be absorbed into the sink of the cold ocean waters. Next the thermohaline circulation carries the CO2-rich sea water deep into the ocean. A millennium later it appears at the surface in warm waters, saturated by lower pressure and higher temperature, to be exhausted back into the atmosphere. Throughout the past 420 millennia, comprising four interglacial periods, the Vostok record of atmospheric carbon dioxide concentration is imprinted with, and fully characterized by, the physics of the solubility of CO2 in water, along with the lag in the deep ocean circulation.
Notwithstanding that carbon dioxide is a greenhouse gas, atmospheric carbon dioxide has neither caused nor amplified global temperature increases. Increased carbon dioxide has been an effect of global warming, not a cause [historically -etl]. Technically, carbon dioxide is a lagging proxy for ocean temperatures. When global temperature, and along with it, ocean temperature rises, the physics of solubility causes atmospheric CO2 to increase.
If increases in carbon dioxide, or any other greenhouse gas, could have in turn raised global temperatures, the positive feedback would have been catastrophic. While the conditions for such a catastrophe were present in the Vostok record from natural causes, the runaway event did not occur. Carbon dioxide does not accumulate in the atmosphere."
So, greenhouse [effect] is all about carbon dioxide, right?
Wrong. The most important players on the greenhouse stage are water vapor and clouds [clouds of course aren't gas, but high level ones do act to trap heat from escaping, while low-lying cumulus clouds tend to reflect sunlight and thereby help cool the planet -etl]. Carbon dioxide has been increased to about 0.038% of the atmosphere (possibly from about 0.028% pre-Industrial Revolution) while water in its various forms ranges from 0% to 4% of the atmosphere and its properties vary by what form it is in and even at what altitude it is found in the atmosphere.
In simple terms the bulk of Earth's greenhouse effect is due to water vapor by virtue of its abundance. Water accounts for about 90% of the Earth's greenhouse effect -- perhaps 70% is due to water vapor and about 20% due to clouds (mostly water droplets), some estimates put water as high as 95% of Earth's total tropospheric greenhouse effect (e.g., Freidenreich and Ramaswamy, 'Solar Radiation Absorption by Carbon Dioxide, Overlap with Water, and a Parameterization for General Circulation Models,' Journal of Geophysical Research 98 (1993):7255-7264).
The remaining portion comes from carbon dioxide, nitrous oxide, methane, ozone and miscellaneous other 'minor greenhouse gases.' As an example of the relative importance of water it should be noted that changes in the relative humidity on the order of 1.3-4% are equivalent to the effect of doubling CO2.
Water Vapor Rules the Greenhouse System
Water vapor constitutes Earth's most significant greenhouse gas, accounting for about 95% of Earth's greenhouse effect (4). Interestingly, many 'facts and figures' regarding global warming completely ignore the powerful effects of water vapor in the greenhouse system, carelessly (perhaps, deliberately) overstating human impacts as much as 20-fold.
Water vapor is 99.999% of natural origin. Other atmospheric greenhouse gases, carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and miscellaneous other gases (CFC's, etc.), are also mostly of natural origin (except for the latter, which is mostly anthropogenic).
Human activities contribute slightly to greenhouse gas concentrations through farming, manufacturing, power generation, and transportation. However, these emissions are so dwarfed in comparison to emissions from natural sources we can do nothing about, that even the most costly efforts to limit human emissions would have a very small-- perhaps undetectable-- effect on global climate.
Water Vapor Confirmed As Major Player In Climate Change
ScienceDaily (Nov. 18, 2008) Water vapor is known to be Earth's most abundant greenhouse gas, but the extent of its contribution to global warming has been debated. Using recent NASA satellite data, researchers have estimated more precisely than ever the heat-trapping effect of water in the air, validating the role of the gas as a critical component of climate change.
Yes - that’s it! Thank you.
Yup! We just had our 4th hottest year.
Something tells me that’s a bunch of hooey - but these persistent BS artists seem to get away with it.
“People awakened by frost quakes’ thunderous booms”
I woke last night to the sound of thunder
How far off I sat and wondered
Started humming a song from 1962
Ain’t it funny how the night moves
When you just don’t seem to have as much to lose
Strange how the night moves
Did in Minneapolis. doesn’t help the infrustructure is old and dated.
instead they’ll blow the money on trains and trolleys.
I think the “explosive expansion of air” explanation is in error.
Definitely. Most journos are hopeless when writing about science or technology.
Same in SW Wisconsin. Twice about 10 days ago. It has happened before, but I always forget, get up and tour the house, looking for cracks or broken windows.
OTOH, it could be the old house contracting &/or trees falling. But these sounded like they were in the house.
Wimps. -36 a few hours north, with wind chill pushing it to -42. Ran both woodstoves flat-out this morning.
Wimpy I am. Spent one winter in Sudbury listening to the locals extol the virtues of “dry cold”.
Never. Again. In. My. Lifetime.
I’m not as far north as Sudbury—but having spent a number of winters in TO, I’ll take -36 up here over walking on a North-South street near the Lake in February with a wicked wind coming off of the Lake. Plus—wood heat is comforting, and who heats with wood in the GTA?
Lots of free firewood lying in the streets here- come down and pick it up and the locals will thank you ;)
Just remmebner, at -45 your pish freezes before it hits the ground. Hence the term: “having a tinkle.”
Tinkle should not be confused with frost quakes, unless
its Michael Buble having his tinkle./s
It was your first time, eh?
We get them all the time from the Ottawa river. At -25c, we start getting them from our deck. They used to un-nerve me a bit at first.
Why don’t they put snow tires on rental cars in winter?
Of all the people who could be helped by snow tires, ......
Both wood stoves going full blast here in Ottawa.
Did you hear about the Propane shortage? Here in eastern Ontario people are only getting 1/2 the propane they ordered, and it’s said this could last until March.
BTW the harbour froze this year, something that only happens a couple of times in a decade.
Haven’t heard about it but not really an issue in a city with gas mains. If it happened in the summer, though, BBQ enthusiasts would treat it as an emergency.
