A dendritic drainage pattern is the most common type.

Smoke deposits of object surfaces can suggest the direction from which the fire originated, and glass and plastics tend to melt in the direction of fire, thus distortion of … The drainage pattern depends on the rock types and geologic structures underlying the stream system. Trends and Patterns of U.S. Fire Loss, 1/17 iii NFPA, Fire Analysis and Research, Quincy, MA List Tables Page Table 1. There were specific burn patterns that fire investigators believed could only be … U.S. Fire Department Responses in 2015 Compared to 2014, 2005, 1995 & 1985 13 .

Curiosity/accidental: nonpathological fire-setters. Table 2. The U.S. Fire Problem in 2015 Compared to 2014, 2005, 1995, & 1985 11 . Types of Forest Fire There are two types of forest fire i) Surface Fire and ii) Crown Fire .

Fires and Losses by Incident Type in 2015 12 . Table 3.

The brocade effect is generally a silver tail effect, and is brighter than the willow or tiger tail effect. Some types of rock are harder and more resistant to erosion than others. However ventilation can affect the path or shape of V-shaped patterns.


If the geology underlying a stream system is fairly uniform—rocks equally resistant to erosion in all directions—a dendritic drainage pattern will develop, as shown in figure 1. As fire burns upwards and outwards, V-shaped smoke/burn patterns may be found on surfaces adjacent to the fire, with the end of the V pointing towards the point of ignition.

Types of Radiation patterns. Common … Sometimes referred to as "repeaters" or "multi … The various marks and patterns permanently imprinted on the structure and contents by the smoke, heat, and fire point the observant fire investigator in the direction of area of fire origin. Crown Fire- The other type of forest fire is a crown fire in which the crown of trees and … C. Cake. The most common type, they often do not understand the consequences of fire-play and tend to be 5 to 10 years old. Fire Pattern Analysis and Case Study Review in Post-Flashover Fires Abstract Until the 1992 publication and eventual acceptance of NFPA 921: Guide for Fire and Explosion Investigations by the National Fire Protection Association, fire pattern analysis was a widely accepted method of determining the presence of an ignitable liquid. The figure explains the radiation pattern of an end-fire array. Table 4. Interventions may include fire-safety education, evaluation for attention-deficit hyperactivity disorder and parent training. Cry-for-help: children who consciously or subconsciously use fire to draw attention to a stress in their life. Bouquet Pattern. The Radiation pattern of end-fire array is uni-directional. Most brocade effects use glitter to produce the long brocade tails. However, in two-dimensional view, it forms a figure-of-eight pattern. Radiation Pattern. Brocade. A major lobe occurs at one end, where maximum radiation is present, while the minor lobes represent the losses. A bouquet patter is a floral-shaped aerial pattern of stars, usually in a spherical shape (see the definition for peony). A spider like effect in the sky, much like fine lace. Surface Fire-A forest fire may burn primarily as a surface fire, spreading along the ground as the surface litter (senescent leaves and twigs and dry grasses etc) on the forest floor and is engulfed by the spreading flames. The common types of Radiation patterns are − Omni-directional pattern (also called non-directional pattern): The pattern usually has a doughnut shape in three-dimensional view.
