A quick or sharp movement from the glacier could cause the crevasse. Fast increases in temperature or the overall global warming can cause the glaciers to form crevasses as well. Also in some cases water flows can cause or deepen crevasses.
In 1986, the Hubbard Glacier in Alaska surged at the rate of 10 meters per day for several months! Friction at the base of a glacier causes the underside to move more slowly than the top. Rapid movement of a glacier causes stresses to build up in the ice, forming cracks, called crevasses, at the glacierâs surface. Crevasses may be small or quite large, and they pose a real hazard to anyone moving about on a glacier.
