Is San Francisco safe from earthquake?
San Francisco is
very vulnerable to earthquakes
. Its three notable faults, covered below, are right-lateral strike-slip faults. This is a type of shearing force where the right block moves toward the fault and the left block moves away. Millions of Bay Area residents live near active fault zones.
How are bridges built to withstand earthquakes?
Instead of a monolithic design, these bridges are
made of columns containing limb-inspired joints and segments
. Hence, in the event of an earthquake, the joints allow some of the energy from the ground motion to diffuse while the segments move slightly, sliding over one another rather than bending or cracking.
What makes a bridge earthquake proof?
By
reinforcing bars with a metal alloy made from a mix of nickel and titanium
, they will flex and snap back into their original shape when the earthquake is over. The concrete is made with small polyvinyl fibres that are coated to bind with the concrete and limit cracking. The concrete has to be made in small badges.
