Not necessarily, those houses are mostly made of stones, cement and other similar materials. Only the roof structure and some other internal structures would use wood, which means a fire would spread much slower than if those were built like american wooden houses.
No lol. Like they literally have way less flammable materials in their homes. The sea air would damage anything flammable over time, too. Best not to have it in the first place.
probably only very bad smoke smell but the actual damage should not be too big.
Still a problem but not as big as you might think.
I am not sure tho because where I live roads are a bit wider
