Had this weird thing happen to me where I, in the span of five turns, met TWO Civs from the other side of the map. Both times their capital was hit by a flood on the same turn I made contact. Notice where Canada is on the mini-map compared to where I am/ what I've explored. Met the Khmer a few turns back too, under the same circumstances. (they're the gold/navy blue civ in the west). Is this some sort of glitch?
