Supershear earthquakes are more likely to happen along long, mature faults like the San Andreas, where many years of activity have ground away a lot of the twists and bumps that might slow down an earthquakes energy. All earthquakes start with P waves, which are fast moving and cause little damage. Over the years, scientists have also found that the duration of slow quakes can vastly differ.
