A new analysis of aftershock sequence statistics and fault geometry fingerprinting

TL;DR

This paper introduces a novel method for analyzing aftershock sequences by examining the linear relationship between cumulative magnitude and time, which helps identify fault zone characteristics.

Contribution

It presents a new approach to fault zone fingerprinting through cumulative magnitude analysis across global aftershock sequences.

Findings

Cumulative magnitude over time shows a linear trend in aftershock sequences.

The slope of this linear relationship characterizes the causative fault zone.

Method provides a new tool for fault zone identification and analysis.

Abstract

We analyzed several aftershock sequences around the globe and calculated the cumulative integral of magnitude over time. This quantity is found to have a linear relationship with time, having a slope characteristic of the causative fault zone.
