What is arc mapping?

Arc mapping is a specific technique used in fire investigation that involves identifying the locations of electrical arcing to help determine the area of origin of a fire. This method focuses on the electrical anomalies that occur during a fire, where arcing can indicate the presence of electrical malfunctions or failures that may have contributed to the ignition of the fire. By mapping these arcs, investigators can gain insights into how and where a fire started, which is crucial for determining the cause and origin.

This technique is particularly valuable because electrical arcing can lead to distinct burn patterns and damage signatures that are pivotal in reconstructing the fire's development. Understanding the precise locations of electrical arcing helps fire investigators piece together the sequence of events leading up to the fire, making it an essential tool in forensic fire analysis.

In contrast to the other options, which involve unrelated activities such as general geographical mapping, archaeological site identification, or climate change impacts, arc mapping is specifically tailored to the needs of fire investigations and the analysis of electrical sources in fire scenarios.
