Example crustal stress dataset
Description
Subsets of the World Stress Map (WSM) compilation of information on the crustal present-day stress field (Version 1.1. 2019).
Usage
data('san_andreas')

with 10 columns. Each row represents a
different in-situ stress measurement:
- id
Measurement identifier
- lat
Latitude in degrees
- lon
Longitude in degrees
- azi
SHmax azimuth in degrees
- unc
Measurement standard deviation (in degrees)
- type
Type of measurement
- depth
Depth in km
- quality
WSM quality rank
- regime
