How do lightning strikes cause bushfires?
Lightning strikes are the main natural cause of bushfires in Australia (human activity is the main overall cause). Australia is a very dry continent with lower rainfall than other continents, particularly during the summer in southern areas. The country is drought-prone, with long, hot, dry summers in the southern states, and vegetation, as a result, becomes very dry, easily ignited and tinder for fires. When sudden storms roll in, as they often do with the clashing of warm and cold air fronts, not only are there lightning strikes which ignite the dry vegetation easily, but these small fires are quickly fanned into blazing bushfires by the strong, gusting winds that accompany these summer squalls.
How many bushfires are struck by lightning strike?
Approximately 50-70% of bushfires are ignited by lightning strikes, depending on the region and climate conditions. Lightning is a significant natural cause of wildfires, especially in areas prone to thunderstorms. However, human activities also contribute to a substantial number of bushfires. The exact percentage can vary yearly based on weather patterns and other factors.
What are the various factors that can cause a forest fire?
