ur knowledge. As dynamic rupture models become more complex recently, questions arise about whether such a scaling property can also be applied in a more complicated situation, especially among rookie dynamic rupture modelers. In this research, we show with an analytical proof that the scaling of the solution in an elastodynamic rupture model under certain frictional parameterizations should hold true in a general sense, no matter what the fault geometry, medium elastic property, or free surface conditions are. Beyond a slip-weakening friction law, our analysis can also be extended to elastodynamic rupture models with time-weakening friction law or rate-and-state friction law. We note that our analysis does not apply to anelastic media, and we suspect that an anelastic dynamic rupture model may not have such a scaling property.
