Many people in the central states of the United States heard explosions at a time when temperatures were below minus 40 degrees Celsius.
Residents of the states of Ohio and Pennsylvania reported hearing explosions almost continuously, the Sun newspaper reported.
The explosions were caused by a sharp drop in temperature, which caused icy earthquakes caused by sudden cracks in the ground, waterlogged rocks or frozen ice.
The massive and rapid temperature drop caused a temperature of minus 40 degrees Celsius to freeze water in the soil and rocks, increasing the volume and pressure of the surrounding areas, causing falls and crackles accompanied by sounds like explosions.
The phenomenon is called "frozen earthquakes" because it looks a bit like regular earthquakes, where the earth moves and cracks and accompanies the sound of explosions.
The polar wind recorded record temperatures of about 61 degrees Celsius below zero in the Thif River Falls area of Minnesota.
