1.0 "Enhanced by Hurricane Dora, high winds were fueling the fires IN Maui and the Big Island"

2.0 "Enhanced by Hurricane Dora, high winds were fueling the fires ON Maui and the Big Island"

if 1.0 suggest that the fires are occurring within the geographical area of Maui and the Big Island.


and 

2.0  indicates that the fires are specifically impacting the surfaces or land areas of Maui and the Big Island
