I arrived, I think just in time to leave my contribution to the discussion ...
One of the most shocking events that I remember regarding the rains was The Vargas Landslide, it was a historical event that marked the lives of thousands of people on the Venezuelan coast. The tragedy occurred on December 15, 1999 and lasted three days of continuous chaos, where heavy rainfall saturated the ground with more than 2,000mm of water, generating a flow rate and going down slopes of more than 30 degrees, bringing landslides with it. earth, rocks, trees and the vegetal layer of the mountains.
Those affected are counted from 10,000 to 30,000 Venezuelans and even the tragedy is in the Guinness Book of Records as the highest number of fatalities due to a mudslide.
