Unlike earthquakes, frost quakes are not potentially deadly-though they might shake your house and rattle your dishes, they won’t destroy buildings. The resulting release of energy cracks the earth and causes an explosive “boom!”įrost quakes typically occur at night, when the temperature drop is most severe. Dear Jack and Verena, A cryoseism is the technical name for a frost quake or ice quake caused by the sudden fracturing of soil or rock due to freezing of water in saturated ground. When the pressure becomes too much, the ground suddenly breaks under the stress. When the frozen water expands in the ground, it releases energy and shifts the. As the groundwater freezes, it expands, pushing and stressing and straining the nearby rock and soil. According to the Smithsonian, this happens when rain and ice seep down into the soil, then freezes and expands. Like a cork that stops up fizzy champagne, the ice entraps the freezing groundwater below. A crust of ice forms at the soil’s surface. Then, the temperature drops quickly to sub-zero. The key ingredient? As their name implies, the catalyst of a frost quake is cold-sudden, bone-chilling cold.įirst, water saturates the ground, perhaps from the melt of a recent snowfall. Instead, frost quakes start with a simple mixture of water and ground.

There are no tectonic plates, fault lines, or volcanoes involved. Unlike earthquakes, however, they are not true tectonic events. Like an earthquake, a frost quake causes the ground to jolt and shake, producing seismic waves and even splitting stone. In scientific terms, you’ve just experienced a cryoseism.

In 2020, researchers from CU Boulder contributed to frost quake modeling research to help predict when and roughly where a frost quake may occur.In the stillness of a chilly winter’s night, a “boom” echoes through the air, and a crack gashes the ground at your feet. Frost quakes happen when the temperature falls so quickly that the moisture in the ground freezes and expands, creating a loud explosion noise, said Stephen Baron, a meteorologist with the. A cryoseism, also known as an 'ice quake' or a 'frost quake,' is a seismic event potentially caused by a sudden cracking action in soil or rock thats frozen due to being saturated with ice or. These conditions are possible in Colorado, though it appears frost quakes are not often reported in the state.Ĭryoseisms can be difficult to predict. They are also more likely to happen in areas where the soil is saturated with water, sometimes after heavy rain. In North America, frost quakes are most common in Alaska, Canada, and the northeastern portion of the contiguous United States, but can happen anywhere that temperatures rapidly drop from above freezing to below zero. These are caused by sudden cracks in frozen soil or underground water when it's very cold,' the service said. Just like earthquakes, they generate tremors and thundering sensations. 'These are frost quakes, also called Cryoseisms. The service later confirmed that this was not an earthquake. The National Weather Service in Caribou, Maine took to Twitter to share that some residents of the area had reported hearing and feeling the ground trembling during recent winter weather.
