tectonicr

tectonicr is a free and open-source R package for modeling and analyzing the direction of the maximum horizontal stress (SHmax) based on the empirical link between the direction of intraplate stress and the direction of the relative motion of neighboring plates (Wdowinski, 1998; Stephan et al., 2023). The following methods are available:

Prerequisites

You must have R installed on your system (see http://r-project.org). To install tectonicr from CRAN, type the following code at the R command line prompt:

install.packages("tectonicr")

Installation

The most recent development version of tectonicr is available from Github and can be installed on your system as follows:

# install.packages("remotes") # install if needed
remotes::install_github('tobiste/tectonicr')
library('tectonicr')

Using the stress measurements from the San Andreas Fault - Gulf of California example, a quick analysis and test against the right-lateral transform plate boundary can be achieved by:

# load example data
data(san_andreas)
data(nuvel1)
data(plates)

stress_analysis(
san_andreas, 
PoR = equivalent_rotation(nuvel1, "na", "pa"), 
type = "right", 
pb = subset(plates, pair == "na-pa")
)

The code produces the underlying results for Fig. 7 from Stephan et al. (2023)

Documentation

GUI

There is a graphical user interface that provides some (limited) tectonicr functionalities. No need to install, just click on the link and you can run tectonicr on your browser:
