Comment on "Earthquakes Descaled"

Abstract

We show that Bak et al.'s unified scaling law cannot be trivially explained by a single Omori aftershock sequence. On the contrary, the spatial heterogeneity of seismicity plays a fundamental role in the unified scaling law, which implies that the law provides a way to quantify seismic patterns in space.
