New evidence continues to arise of the San Andreas fault continuing a period of "after slip" after the 6.0 Parkfield earthquake in 2004. The fault is found to continue slipping, with evidence of it moving as much as 5cm in one day. This raises more questions about the extent of damage to buildings along the fault line, even 12 years after the damaging earthquake. Such a degree of slipping is a problem for California residents as many buildings and cities are built right on top of fault lines. Continued slipping will only cause more damage and run up expenses. There does not have to be an earthquake for damage to occur.
