stress_data: 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')
data('tibet')
data('iceland')

Format

A sf object / data.frame 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

regime

Stress regime

An object of class sf (inherits from data.frame) with 1126 rows and 10 columns.

An object of class sf (inherits from data.frame) with 1165 rows and 10 columns.

An object of class sf (inherits from data.frame) with 490 rows and 10 columns.

Details

'san_andreas"

contains 407 stress data adjacent to the San Andreas Fault to be tested against a tangentially displaced plate boundary.

"tibet"

contains 947 stress data from the Himalaya and Tibetan plateau to be tested against an inward-moving displaced plate boundary.

'iceland

contains 201 stress data from Iceland to be tested against a outward-moving displaced plate boundary.
