Soil liquefaction causes the sandy soil underneath the excavator to float like water in British Columbia, Canada.
A worker operating an excavator captures the moment the large sandy area beneath the machine bobbing like waves in Kitimat, British Columbia, Canada, on August 20, according to Newsflare. The construction worker ventured to poke down an unstable surface with the machine’s bucket.
Soil liquefaction can be dangerous.
The cause of sandy soil ripples is a phenomenon called soil liquefaction , which occurs when soil is saturated with water and subjected to pressure due to sudden movements such as vibrations from an earthquake or an excavator’s bucket. The ground loses its strength and stiffness, exhibiting water-like properties. Soil liquefaction can be dangerous. During earthquakes, cars, roads, and even buildings can be sucked into the subsoil.
In 2011, Japan suffered a magnitude 9 earthquake that caused widespread soil liquefaction. Areas with a high water-to-land ratio near coastal areas, ports and rivers are most affected by this phenomenon.
Hundreds of streets in Christchurch, New Zealand were also destroyed by soil liquefaction in the 2011 magnitude 6.3 earthquake. Roads were covered with mud spewing from the ground after soil liquefaction occurred. go out.
