![]() 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. Abstract Fractures in frozen soils (frost quakes) can cause damage to buildings and other infrastructure, but their formation mechanisms remain poorly understood. 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. In the new study, 'we were actually able to collect data on a frost quake and use that data to determine what the cause was,' said study co-author Roseanna Neupauer, a hydrogeologist at the University of Colorado Boulder. 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. However, since frost quakes often happen in sparsely populated areas, much was unknown about their specific origins. 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. ![]() This causes cracks and ridges to form in the ice, which can produce seismic waves that may then be recorded by seismographs. Frost quakes occur when very cold air interacts with soil that is saturated after recent rain or snow has seeped into the ground.
