One of the most severe impacts of earthquakes is soil liquefaction. After having watched a program at NatGEO, I remembered I had this short video on a physical model that I recorded during an Engineering Fair in Tohoku, Japan, back in 2006. The small tubes in the model are manholes. Learn, enjoy while watching the experiment, and find out how harmful liquefaction can be.
Glossary
Liquefaction.- A phenomenon in which the strength and stiffness of a soil is reduced by earthquake shaking or other rapid loading.
