Genesis of Chimera. Chimera breathes fire. Fire and lava go together. Lava comes from volcanoes. The most famous volcano is Mt. Vesuvius. Mt. Vesuvius was in Pompeii. Pompeii was destroyed by Vesuvius.

All of this has something to do with the Chimera's fire, which is possibly the reason the arena (Pompeii) is burnt. Perhaps there's a Chimera mutt. Perhaps there will be sixteen tributes who perish, or perhaps sixteen family members. Perhaps sixteen make it out alive. Perhaps the sixteenth day is special. Perhaps the volcano erupts every sixteen hours. Whatever the case, it has something to do with the number 16.

It might also have to do with revenge, or repetition. The president's family was killed. Maybe the same happens to these tributes, with only one membe. Going along with this repetition, the whole of Panem was in a barbarian state after that, so maybe after a tribute and/or their family member dies, maybe the rest of their family at home go crazy, or the tributes in the arena go crazy. Or something here to do with 16.

Those are my guesses.
