Faulty Behavior (image) California Institute of Technology Share Print E-Mail Caption Numerical simulations illustrate that fault segments can move slowly and stably over long periods of time and later host large earthquakes. Dashed lines represent slow slip every 50 years along a cross-section of the fault, with the numbers indicating the simulated time in years. Earthquakes are shown by solid lines plotted every second. The area marked patch B can both slip slowly (e.g., dashed lines above the 4,500 year mark) and participate in large earthquakes (e.g., yellow event).
