San Francisco needs earthquake proof buildings because in California theres a large fault line called the San Andreas fault line. It is along this fault line that lots of earthquakes occur.
Most earthquakes occur on active fault lines such as the San Andreas fault in California. Most fault lines are under water but some come above water, such as the San Andreas fault in San Francisco and the fault line in Iceland. The San Andreas fault caused the great fire in San Francisco.
San Francisco has been built on a fault line called the San Andreas Fault. It is a fracture in the crust of the Earth. San Francisco sits on the edge of the pacific tectonic plate. The pacific tectonic plate collides with the North American tectonic plate, causing earthquakes. San Francisco also has soft soils so it's very easy for an earthquake to happen that causes bad damage.
