What happened in Caronia, Italy in 2004?

Oregon is now well on it's way into summer with the daily temperatures now reaching into the mid 80s. Now, ordinarily that doesn't bug me one bit, but here in my section of Oregon it gets humid and uncomfortable during the summer months, only getting worse as they drag on. Bizarrely this time of year in Oregon, everyone loves. They spend all winter complaining about the rain, or in the case of this last one, the snow, but love it when they are able to go outdoors without coats or umbrellas during the summer. However, this is accompanied by "Oh it's such a nice day, but to hot." which in my opinion completely defeats the concept of "Nice day." All that pales in comparison though to what happened in the early months of 2004 in Caronia, Italy, where for no apparent everyday items would catch fire.

At first they were electrical items and many began to search for reasons, such as power surges. However the phenomenon, as reported by some witnesses, even affected items that were not plugged into walls, including unplugged items, battery operated items, and possibly even standard non-electrical furniture.

Throwing another twist into it all cars and cell phones began having issues as well. In particular, car alarms would go off for no reason, or as reported in one case, the engine turned on when all the doors were locked and no one was in it. And all incidents ranging from the fires to the unusual car and phone behavior only seemed to occur when people were present to witness it.

So what was happening there in Caronia? No one really knows. Many blamed it on supernatural causes, such as demons or aliens. Others thought some bizarre natural phenomenon such as electric charges released from the Earth. And some thought someone was playing a game with Tesla style inventions. Till this day however no satisfactory answer has been found.
