Propagation may take place on a single fault , but in many cases the rupture starts on one fault before jumping to another , sometimes repeatedly . The 2002 Denali earthquake initiated on a thrust fault , the Sutsina Glacier Thrust , before jumping onto the Denali Fault for most of its propagation before finally jumping again onto the Totschunda Fault . The rupture of the 2016 Kaikoura earthquake was particularly complex , with surface rupture observed on at least 21 separate faults
