![]() In the Canadian province of British Columbia, in a village called Lytton, the country's all-time hottest temperature record was broken three times, with the highest recorded on Tuesday at 121.28F. Whatever the cause of the Alaska ice quakes, the fact remains that northwestern parts of North America are experiencing unusually hot temperatures at the moment. ![]() Likewise, this land can rise again when the glaciers melt.Ĭhris Rollins, the lead author, found a subtle correlation between this earth rebound effect and earthquakes. Frost quakes (or 'cryoseisms,' if you want to get technical), are seismic events that typically occur in Earth’s boreal or cold, temperate regions. In a summary of the paper, the University of Alaska Fairbanks, with which the study's lead author is affiliated, said the weight of glaciers can cause the land beneath them to sink. In a March 2021 research article, scientists found that ice loss near Alaska's Glacier Bay National Park has influenced the timing and location of earthquakes in the area. The Encyclopedia Brittanica, however, uses that same definition for both ice quakes and frost quakes.īoth are examples of a cryoseism-in which snow, ice, or rock suddenly cracks because of changes in stress, whether it be expansion or contraction.įurther complicating matters is the fact that scientists have known for years that melting glaciers have caused earthquakes in areas that are otherwise stable. It states that a frost quake occurs when very wet soil freezes quickly and expands, which then puts stress on the soil and causes it to fracture. Ice quakes may also be referred to as frost quakes, though the AGS makes a distinction between the two. Ice quakes are not the same as earthquakes, which are instead caused by the shifting movements of tectonic plates. People often hear this noise more acutely at night because ambient noise during the day tends to drown. This causes cracks and ridges to form in the ice, which can produce seismic waves that may then be recorded by seismographs. Ice formed on a tree at the University of North Alabama on Feb.
