How to increase random event occurrences?

I was wondering if anyone could guide me in increasing random event occurrence.

Would this make the game unbalanced? Any other relevant info about this change would be appreciated.

Thank you. Great mod btw, CIV the way civ should be.

Plz someone could answer how to do?

Tweak the chance on a per era basis with the <iEventChancePerTurn> value.
