  abstract = {{T}he impact of earthquakes can be severely aggravated by cascading secondary hazards. {T}he 2018 {M}-w 7.5 {P}alu, {I}ndonesia, earthquake led to devastating tsunamis and landslides, while triggered submarine landslides possibly contributed substantially to generate the tsunami. {T}he rupture was supershear over most of its length, but its speed was unexpectedly slow for a supershear event, between the {S} wave velocity {V}-{S} and {E}shelby's speed root 2{V}({S}), an unstable speed range in conventional theory. {H}ere, we investigate whether dynamic rupture models including a low-velocity fault zone can reproduce such a steady supershear rupture with a relatively low speed. {W}e then examine numerically how this peculiar feature of the {P}alu earthquake could have affected the near-field ground motion and thus the secondary hazards. {O}ur findings suggest that the presence of a low-velocity fault zone can explain the unexpected rupture speed and may have mitigated the near-field ground motion and the induced landslides in {P}alu.},
