Mudslides

Mudslides, also known as mudflow, are a natural disaster in which mud and collected debris rapidly flow in a downward direction. Mudslides generally occur in areas where large amounts of vegetation has been destroyed, lands with steep slopes, and places where surface runoff is directed. The largest mudslide in history happened in 1980 when Mount St. Helens in Washington state erupted.

What could be done to prevent mudslides or landslides?

Landslides or slips in urban areas, almost always have a source of water as their cause. Broken water or sewage mains are often to blame.

They occur where the ground has been inadequately consolidated, as in a subdivision of land; or where the land is steeper than its natural rest angle.

Rainfall in storm conditions will often saturate the soil structure, exacerbating the problem.

What countries were affected by mudslides?

Mudslides are common and happen frequently. However, many of them are small and do not cause damage. The United States and Italy are two countries that mudslides occur in. Greece and Turkey also experience mudslides.

A mudslide occurs whenever mud and water flow very rapidly down a hill. They are common in places like Washington, California, and Puerto Rico.

A mudslide - also called mudflow - is a flow of dirt and debris that occurs after intense rainfall or snow melt, volcanic eruptions, earthquakes and severe wildfires. The speed of the slide depends on the amount of precipitation, steepness of slope, vibration of the ground, and alternate freezing and thawing of the ground.

Typically, a flow may start after a heavy rainstorm, accelerate and eventually achieve a speed of 10-35 miles an hour. As the slide accelerates, the liquid mud picks up everything in its path - rocks, boulders, even trees and cars. The flow grows, accumulating more debris, and when it reaches a plateau, spreads out over the area.

Often, areas that have experienced a mudslide are more likely to suffer from recurring slides.

Mud that lay on a hill and when heavy rain comes the mud flows down the slope to create a MUDSLIDE.

How do mudslides kill people?

Asked by Wiki User

Mudslides, or mudflows as they are more properly called, can kill people in two ways. First, the sheer force of the mudflow or the debris it carries can crush people. Those less fortunate may be buried may be trapped in the mud once it stops moving. People who are completely buried will suffocate. Worse still, people who are partly buried may die of thirst if rescuers are unable to reach them

How does rain fall affect mudslides?

Asked by Wiki User

If rainfall is heavy enough or over long periods, the clay and sand can become slippery and the material resting above looses cohesion. Slope stability is compromised and a landslide would occur.

Where does mudslides happen?

Asked by Wiki User

Mudslides happen in particular after heavy rain. Not always as a result of the ground being wet. Fresh water will over time wash away the salt deposited in the mud. When this salt is wahed away, the mud becomes more liquid with vibration.

It is important with vegetation and large trees with a big rootsystem in order to stabilize soil in dangerous areas.

Cutting down of trees and removing roots can over time be a considerable factor.

On average, thousands of people die from mudslides globally each year. Factors such as location, frequency, and severity of mudslides contribute to the variation in the number of fatalities.
