It has been determined that there is most likely a special frequency that can extinguish a flame, generally between 40 and 50 hertz. Theoretically the pressure drop produced by the sound wave can extinguish flame (Snyder, 2008).

146.52: On this frequency, you can listen in on ham radio users for non-repeater communication. 154.28: Used by local fire departments for inter-department emergency communication. 155.60: Used by state and local agencies for inter-department emergency communications.

Fire frequency is also a mathematical expression of fire occurrence or rate, such as the average time interval between successive fires or the number of fires within a specific period of time. It is a generic term referring to general fire occurrence or rate (Firewords 2018).

This is happening for several reasons, including more lightening, desertification, deforestation, persistent droughts, urban expansion, resource exploitation, fresh water depletion, and higher global temperatures, just to name a few.

The extent of area burned by wildfires each year appears to have increased since the 1980s. Of the total area burned each year from 1984 to 2018, the proportion of burned land suffering severe damage has ranged from 5 to 23 percent (see Figure 3).

A fire warning (SAME code: FRW) is a warning issued through the Emergency Alert System (EAS) in the United States by civil authorities to inform the public of major, uncontrolled fires (usually wildfires) threatening populated areas and/or major roadways.

“If you are to go into water, whether a pool, dam or the sea, you risk not only a lack of oxygen due to smoke and intensity of the air temperature, but also exposure to deadly radiant heat,” she said.
