The above maps show the pattern of fire spread in the Los Angeles County. As seen from the map above the fire spreads to the green areas on the map since the slopes are steep here and there is grass and trees that the fire can feed on. The fire prone area as we can see is right in the center of LA county and fortunately only a few highways pass through it.
The theme of my map is the fire spread due to topography. The fire spreads form the the higher slopes to the lower slopes. Also the wind direction affects the spread of the fire in the sens that the fire spreads in the direction of the wind.
The fact that the fire prone area is right in the center of the county is highly dangerous although since very few highways pass through this region, very few percentage of the population is prone to it.
