OK guys, if I can claim some specialist knowledge on forestry matters I will explain how fires start spontaneously.
Given the right conditions, prolonged dry spells, high temperatures, low humidity, forests can catch fire easily. The actual fire lighting can be through friction, as when two branches rub against one another, through optical means, ie focusing of sunlight through a coke bottle or bottom of concave beer can, or through natural causes such as lighthning. The presence of volatile oils like terebinthine from pines helps the ligthing process.
Here we had fires that started at night, in a a linear progression, each outbreak coming several minute after the previous one. Fire starting at night when temperatures, wind and optical causes are at the least favorable, makes this whole deal strange.
On the other hand, as per the article that Bananiot quoted, Greek forests are not particualry well managed when it comes to things like clearing low growth to prevent ground fires or trees to prevent canopy fires (the worst kind). So when a fire does start it tends to gain dimensions and cause disproportionate damage.
What the article did not mention is that the eco lobby in Greece, for PR reasons, actively opposes the professional management of forests. Claiming that it is lumbering masquerading as thinning. Note that the Eco lobby has not made a single statement during these fires. You people in Cyprus will learn about the Eco lobby soon enough, it is part and parcel of the EU way of doing things.
