Climate change is not just causing more floods and fires, but also changing the risk and effects of earthquakes, according to a new report.
The report notes that climate change is having an impact on seismic risk, both through increases in earthquake rates in area where ice sheets in the Arctic are thinning quickly, “as well as through degradation of permafrost, resulting in soils that are more vulnerable to strong shaking and failure during shaking.”
Research published by the University of Alaska Fairbanks Geophysical Institute in 2021 found a link between a magnitude 7.8 earthquake in 1958 and ice loss near Glacier Bay National Park in Alaska’s Panhandle region near the border with the British Columbia, a region already a vulnerable to earthquakes.
Greenland, meanwhile, has seen a surge of glacial earthquakes as pieces of ice several cubic kilometres in size can cause earthquakes when they break off glaciers.Snow-covered houses and the downtown skyline are seen after a snowstorm, in Vancouver, B.C., Nov. 30, 2022.
