Frost quakes were heard overnight and early Tuesday morning, with dozens of loud booms reported across the GTA.

CityNews meteorologist Natasha Ramsahai said a frost quake is caused when rain and ice seep down into the soil and then freezes when temperatures drop.

“Water expands when it freezes and when it expands in frozen soil it literally puts a lot of stress on that dirt and will release that energy all of a sudden, very much like an earthquake releases that energy and shifts the ground,” she said.

CityNews and 680News readers certainly heard them, waking up to booms from Burlington to Woodbridge. One person said it sounded like someone breaking into her home! Did you hear one? Let us know.
