Resumo	(*)(?)	Wildfires are important elements of ecosystems that can have significant environmental and socio-economic impacts. The spatio-temporal dynamics of single events are very complex and have been studied mostly through the application of models and by reconstruction using multiple data sources. Both are time consuming approaches with high associated uncertainties and laborious applicability to other case studies. In this study we propose to reconstruct the fire events and extract relevant parameters using solely remote sensing data for a large time span and spatial region. We combined a burnt areas dataset with MODIS active-fire detections to reconstruct the fire events. The structure of fire spread was described using graphs which were used to calculate the main fire routes. Using the circular statistics each routes mean fire spread direction was calculated. The approach showed promising results providing a valuable reconstruction of the fire events and retrieval of important parameters related to the propagation of single fire events. The methodology can be easily applied to other regions of the globe since it depends on a very limited amount of input data and is based on the morphological spread structure of each fire event. The more conventional approaches, such as fire spread modeling, would greatly benefit of the integration of information extract from remote sensing data.
