The truth is, mudslides don’t just cause dirty messes. They are extremely destructive, even deadly!One extreme case in China wiped out much of the town of Zhouqu, taking at least 330 lives.Mudslides are made up of rock, dirt, random debris and of course, water. They can start off slow and gradually pick up momentum (and more mud!) as they move downward. This incredible force is capable of taking out large trees, cars, nearly anything in its path.
Pretty frightening. So how do we know when a mudslide is coming?(The bad news is that mudslides can occur any time of the year and can come without any warning!)
Most mudslides are caused by excessive rain, which loosens the soil and starts to wash it downhill. But there are other causes too. Ground movement (earthquakes or volcanoes) can trigger a slide. It can also occur in areas where there is a lot of alternating of freezing and thawing in the ground. Even wildfires contribute to mudslides by leaving a lot of loose debris on the forest floor.
However, not all the causes are natural. Man can create a mudslide-prone area through careless building construction or any other type of land modification. Most builders inspect the land before it is built on and then drain, if necessary.
