Scaling Relations for Earthquake Source Process

Abstract

This paper reviews recent progress on the scaling studies for earthquakes, including some slow earthquakes. While a standard scaling law for macroscopic parameters with geometrical similarity is valid for most cases, several studies suggest its limits and exceptions. The scaling of seismic energy has been a hot topic in this decade. We review new kinds of scaling studies on seismic source complexity, focusing on three aspects of earthquake evolution. Finally we compare the scaling law for slow earthquakes along the Nankai subduction zone with various similar phenomena worldwide.
