The earthquakes get so bad in California and so often that if the house is were not on rollers they would fall apart, the rollers help reduce the stress from the earthquakes for the buildings. The earthquakes which as explained above is caused from transform boundaries. in California this fault is called the San Andreas Fault. The San Andreas fault has been building up potential energy for years upon years till the plates can't hold the energy and have to release it. Even though the plates have given off some of the potential energy they are still building up more potential energy
