Multiple Choice

Which type of fire cause may occur from lightning strikes or earthquakes?

Fires are classified by where the ignition comes from. Natural causes include ignition from natural phenomena, like lightning or events such as earthquakes that lead to ignition sources (for example, by damaging gas lines or electrical systems). So, whether a fire starts directly from a lightning strike or indirectly because an earthquake causes a gas leak, it fits the natural category because the initiating event is a natural phenomenon rather than human action. This differs from accidental causes (unintended human actions or equipment failures), incendiary causes (deliberate setting of a fire), and undetermined causes (when the origin cannot be determined).
