stress_data function

Example crustal stress dataset

Subsets of the World Stress Map (WSM) compilation of information on the crustal present-day stress field (Version 1.1. 2019). data

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: MMeasruement standard eviation (in degrees)
• type: Type of measurement
• depth: Depth in km
• quality: WSM quality rank
• 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.
