How does historical fires help firefighters learn? specifically..

Retype from previous question:

Well, not only does it help firefighters learn, but it helps everyone learn. In the case of historical fires, it actually helps them to grasp how to deal with them, how to prevent the most amount of casualties and how to prepare areas that are prone to fires. For example, the large 2020 california wildfires caused a large amount of damage. Teams have studied the incident to see how they can prevent further large fires from occuring — or how to minimize the damage if they do occur.

I hope that helps!!
