Earthquake Liquefaction Example

submitted by Mordhaus

7 years 9 months 2 weeks ago

This video, courtesy the Illinois Geological Survey, shows how earthquake liquefaction can affect buildings and buried structures. The concept presented is elementary but will provide you a basic understanding of what happens when saturated soils are shaken by earthquakes. The brass weight represents a building or structure and the ping pong ball represents a buried storage tank.

For those who are wondering of the actual effects that this causes in a earthquake. Water and Sand get forced up. After the last big quake in christchurch the water was upto my knees in about 2minutes. Thick sand/water mix covered everything. Pipes below the ground were often forced up and out, and houses sunk into the ground. Sinkholes, uneven ground, damages roads and footpaths. Its a pretty nasty effect.... and thats without the quakes force alone.
