There should be, but there isn't. Unfortunately there is no way to prevent or even mitigate the damage of fires... which is a questionable design choice.
To be honest, while some societies managed to mitigate fires in cities and towns fairly well, nobody that I know of did very well at mitigating damage from 'wild' (forest) fires, which is what the natural disaster in Civ VI represents. Few people know that at the same time the great Chicago Fire happened in 1871, there was a fire in Wisconsin that swept through rural areas and killed 5 times more people than the urban Chicago fire did.
And, of course, even in the 20th and 21st centuries we aren't doing much better at mitigating the effects of wild fires, even without the effects of a more energetic climate system.
On the other hand and, if the game wanted to show a very common Urban Disaster (and I am NOT advocating this) Urban Fires have been a constant, and occasionally catastrophic, part of city development since Antiquity. Not counting those caused on purpose (sacks, sieges, etc), some examples:
Between 6 and 36 CE Rome had 6 major fires, culminating in the "Great Fire of Rome" that burned for 9 days in 64 CE and destroyed 10 out of 14 districts in the city. The destruction was so widespread that they never got a body count.
Constantinople, London, central Rome all extensively burned between 406 and 847 CE.
Most of London burned down twice in the Medieval period: 1135 and 1212, and the second killed at least 3000 people.
Jamestown, in Virginia, burned down in 1608 - so small size was no defense.
66% of Edo, the largest Japanese city, burned in 1657, then Nagasaki went up in 1663 a bad decade to be in Japan!
Between 1820 and 1845 just in the United States Savannah, Fayetteville (twice), Augusta, Charleston, and New York City (twice also) had major, destructive urban fires.
In my home state of Washington, in 1889 Seattle, Spokane and Ellensburg all had their central business districts wiped out by fire.
Point being that Urban Fire was much more common than the wild fires that are the only thing the game has depicted in the past, but they would be a wretched mechanic to include: while they allow extensive rebuilding of the city, they cause temporary major losses of population, industry, and depending on which buildings go up, culture and religion. And even the best efforts only rarely stop them beore they do appreciable damage. I can't think of anything more calculated to cause Rage Quit behavior.
