OAF Tools - R package

September 20, 2022

This repository contains the source code for the oaftools package. The package creates visual tools to study aftershock behavior and the performance of the Operational Aftershock Forecasting system. The visual tools are:

A global map, rendered by Leaflet to show the distribution of earthquakes with forecasts
A local map, rendered by Leaflet to show the aftershock sequence and the aftershock zone radius in geospatial context
A magnitude-time plot, which is used to look for patterns in the aftershock sequence
A cumulative number plot, which is used to compare the productivity of the aftershock sequence to a Reasenberg and Jones (1989) aftershock model
A magnitude-frequency plot, which is used to understand the distribution of earthquakes and compare the cumulative number of earthquakes above a given magnitude to Gutenberg-Richter distributions
A forecast success plot, which visually represents the number of successful forecasts for a given magnitude.
