The ground heaves like a wave of water under a digging bucket
A worker who controls the excavator records the moment when a large sandy area underneath the bobbing machine floats like ripple waves in Kitimat, British Columbia, Canada.
The phenomenon of liquefaction of soil makes sand soil underneath excavators dug out like water in British Columbia, Canada.
A worker driving a excavator records a moment of large sandy soil underneath a bobbing bobbing machine like ripples in Kitimat, British Columbia, Canada, on August 20, according to Newsflare. The construction worker risked putting down a test on the less stable surface with the machine's bucket.
Liquid liquefaction can be dangerous.
The cause of rippling sandy soil is due to the phenomenon of liquefaction soil , occurs when the soil is saturated by water and under pressure due to sudden movement such as vibration from earthquake or excavator bucket. The soil foundation loses strength and stiffness, exhibiting water-like properties. Liquid liquefaction can be dangerous. In earthquakes, cars, roads and even buildings can be sucked under the ground.
In 2011, Japan suffered a strong 9th earthquake that caused widespread land liquefaction. Areas with a high proportion of water to land near coastal areas, ports and rivers are most affected by this phenomenon.
Hundreds of streets in Christchurch and New Zealand also suffered from soil liquefaction during the 6.3-magnitude earthquake in 2011. The roads were covered with mud sprayed from the ground after liquefaction occurred. out.
