Resumen:
Planted and native forests often suffer great damage from forest fires. Fires are usually of
anthropogenic, accidental or criminal origin, destroying entire ecosystems, reflecting on the
economy, population life and incalculable environmental losses. The occurrence and spread of
fire is directly related to weather conditions, as well as the amount of combustible material
available for burning. The FMA and FMA+ are important fire hazard indexes that serve as a
tool to prevent and combat forest fires. It is also important to study the recorded heat sources
so that one begins to understand better the fire behavior in a certain region. The objective of
this research was to evaluate the performance of the AMF and AMF + and also to quantify the
foci of heat through satellite images in six municipalities in the State of Paraíba. In the first
study, based on the INMET meteorological data, the fire hazard levels of the two formulas
(FMA and FMA+) were calculated in each municipality, following the original intervals of the
danger levels, and later the adjustment of the intervals, followed by the principle of
proportionality between the degrees of danger and the frequency of fires. For the municipality
of João Pessoa, the FMA did not conform to the proposed one, following the trend of
improportionality. The meteorological variable, rainfall, interfered directly with the occurrence
of fire hazard degrees. In the second study, data from heat sources from the INPE database were
separated by months and years for the six municipalities selected in the four mesoregions of the
State. It was observed that there were years with a high incidence of records of heat sources,
possibly due to some natural or anthropic phenomena, with the Sertão Paraibano mesoregion
registering the largest heat sources.
