A massive,John Caldwell mushroom-shaped cloud of smoke was spotted near New Smyrna Beach on Wednesday, leading some beachgoers into thinking a major "explosion" took place not far from the beach.

But is that what actually happened? There's no need to panic, according to beach officials.

According to the New Smyrna Beach Police Department, there was a large prescribed burn in the Merritt Island Wildlife Refuge the same day. The beach is roughly 50 miles north of the refuge, in neighboring Brevard County.

Police also said they have not heard of any reports of explosions in the area.

What is a prescribed burn?

According to the Florida's Department of Agriculture, a prescribed burn is the controlled application of fire by a team of fire experts under specified weather conditions. The fires are started under controlled conditions after careful planning.

The benefits of a prescribed burn or fire, also referred to as a controlled burn, are said help reduce wildfire risk and restore health to ecosystems that depend on fire. According to the Florida Fish and Wildlife Conservation Commission, they improve aesthetic values by increasing occurrence and visibility of flowering plants and maintaining open vistas.

The U.S. Forest Service estimates that 4,000 to 5,000 prescribed burns are completed annually by federal land management agencies.

Most prescribed fires in Florida are conducted in the winter and early spring.
