This is because the cold weather has brought with it an unusual phenomenon known as 'frost cracking' that can cause tree trunks to literally burst outward like an explosion.

According to meteorologist Max Velocity, states particularly at risk of this right now include Minnesota, Michigan, Wisconsin, North Dakota and South Dakota as well as parts of Iowa and Illinois.The phenomenon occurs when sap and water inside the trunk freeze, causing the interior of the trunk to expand and push outward against the bark until it suddenly and catastrophically gives way.

The resulting fracture can occur so violently that the sound often resembles a gunshot gong off.

The problem is particularly prevalent right now as parts of North America have been subjected to extreme cold with the temperature in some states plunging as much as 30 degrees.
