Our EGU 2020 presentation compares field-based and numerical models of distributed off-fault inelastic strain from the Sandia half-graben in the Rio Grande Rift, New Mexico.

Fracture intensity, the number of fractures per unit length, can be used as a proxy for quantifying bedrock damage adjacent to crustal-scale faults. With collaborators at LDEO, CNRS, and Univ. of Lausanne we combine field measurements of fracture in…

Fracture intensity, the number of fractures per unit length, can be used as a proxy for quantifying bedrock damage adjacent to crustal-scale faults. With collaborators at LDEO, CNRS, and Univ. of Lausanne we combine field measurements of fracture intensity and erosion with numerical modeling to investigate how long term (over many seismic cycles) permanent deformation accumulates in the upper crust.
