Subsets of the World Stress Map (WSM) compilation of information on the crustal present-day stress field (Version 1.1. 2019).
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
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.
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.
'icelandcontains 201 stress data from Iceland to be tested against a outward-moving displaced plate boundary.
