Andancas, a Portuguese dance festival, suffered a horrible setback when 422 cars caught fire and attendees had to be evacuated.

Several cars exploded in the fire, which was all caught on video by a lot of people. You can see how bad the situation was, right here.

Via YourEDM, this appears to be the cause of the fire: Carlos Guerra from the Portuguese National Civil Protection Authority said, “”The fire started in a vehicle and spread rapidly to other vehicles and then to the surrounding bush.”

People took to Twitter and Facebook to express their thoughts on the massive fire that took place.

Be careful, guys. This could easily happen to you too, at festivals.
