The SAFZ started moving about 28-30 million years ago and has horizontally slipped (transform motion) a total of about 300-350 km (186-220 mi) since it began moving. Depending on where the earthquake hits along the Mission Creek strand, some of that seismic energy is going to turn away from the densely populated areas, Burgmann said.
