Fault Zone Widths as a Parameter in Seismic Hazard Estimates

Lead PI: Dr. Bruce E. Shaw

Unit Affiliation: Seismology, Geology and Tectonophysics, Lamont-Doherty Earth Observatory (LDEO)

Global
Project Type: Research

DESCRIPTION: The team will develop parameterizations for fault system geometry by combining their previous method of extracting fault branches and angles and fitting a Y shaped object to it with new measures of the CGS Quaternary surface traces. Then historical large ruptures will be compared with these measures.

OUTCOMES: New simulation capabilities raise the possibility of generalizing beyond backslip models.
