An Earthquake Tears The Ground Open Underneath His Feet
Jul 20, 2015
Subtle chasms like this one are caused by liquefaction, where loose soil acts like a liquid. While the ground might look solid, during an earthquake, the loose layer of water-saturated soil that sometimes lies beneath will begin to act like quicksand. This causes the surface to tear apart and even sink or rise.
Today, most places that are prone to liquefaction have been identified through geological studies and precautions have been taken; but, as this video show, you can never be too careful.
In the movies, earthquakes are portrayed as literally earth-shattering events, with buildings collapsing and highways breaking apart and rising dozens of feet into the air. While this is definitely a possibility, reality isn't always that dramatic.
