Interesting this publication, @ladyrebecca. Geologists have scientific explanations for these floods, but the people don't know them and turn them into beautiful and in some cases funny stories that pass from generation to generation as legends. In my country, there are also towns disappeared by floods and from which many legends have arisen. There are also stories of villages intentionally disappeared by the hand of man as is the case of the Potosí people in the state of Táchira, a town from which they evicted its inhabitants to make a dam and was flooded, only the cross of the church was visible, then with the effects of the El Niño phenomenon and the drought the church emerged and many parts of this town reappeared 30 years later. I would like to share this link so that you may know this event in our history:
