The town of Paradise, CA, population 26,500 people. 71 dead and many more missing. At least 9,800 homes destroyed. In this one fire 90% of the town was destroyed. And worst of all, these people were burned alive. About the most horrible way someone could die.
Unlike a hurricane or tornado, there was no advance warning that this fire could happen, to allow these people to prepare and evacuate. Wild, scary stuff.
