What time of year do landslides occur?

Answer 1

at lest 300000 landslids happen each year

Answer 2

Landslides typically occur after periods of heavy rain, when the ground has become waterlogged and unable to hold together. However, landslides can also be triggered by mining, leaking water pipes, earthquakes and volcanic eruptions.

Answer 3

Depending on the cause(s), landslides can last just a few seconds up to a minute or so. However, they may be on going as forces that continually act upon the affected area dislodge more sediments.

Answer 4

As one example, the landslide in Oslo, in Washington state occurred after it had rained many days. It occurred so suddenly, people in homes had no warning or time to escape. In less than 1 minute, an entire cliff of a hillside sheered off, slid down the height, and continued for one mile beyond the houses. Scientists who study landslides were surprised to see how far the mud, trees, and boulders traveled. But that happens because the water saturated ground forms a slippery surface between the dirt particles, so there is no friction. Mud becomes as smooth and slippery as if standing on a sheet of ice! They show a documentary on You-Tube where scientists built a large trough down an incline. The dump in dirt, then add in electrodes to measure when, how fast, and how much water content is needed to made particles of earth slide against each other. Then, they turn on water and wait for the controlled slide to occur in the experiment. Once saturation occurs, it can take mere seconds for the mass of "land" to move as a whole, sending the top to bottom of the soil (in distance) to become one mass of moving earth.

In this documentary, scientists say the Oslo mud traveled at 60mph in less than 1 minute! The trough experiment I mentioned is about halfway through this video. It is fascinating to watch the experiments!

Answer 5

Landslides can occur at any time of the year, but they are more common during periods of heavy rainfall, rapid snowmelt, or seismic activity that can destabilize slopes. Each region may have specific times of year when landslides are more likely, depending on the local climate and geological conditions.

Answer 6

It is difficult to estimate how often they occur, because it can depend on the weather (like heavy rain).

Answer 7

It takes about a butt crack and a half and a 5 dumps for a landslide to occur.
