Nelson, A.R., Kelsey, H.M., and Witter, R.C., 2021, Radiocarbon ages, age-model code, and other supplemental data for Nelson et al. (2021), A maximum rupture model for the central and southern Cascadia subduction zone - assessing ages for coastal evidence of megathrust earthquakes and tsunamis: U.S. Geological Survey data release, https://doi.org/10.5066/F7S75DTS.

Type: Related Primary Publication

The purpose of this data release is to make available to interested researchers data for Nelson et al. (2021) (referenced in the Summary), which describes a compilation of new and previously published radiocarbon ages from Bradley Lake, a coastal lake in southern Oregon, and from 7 of 13 tidal wetland sites along the coasts of Oregon and northern California. The ages are used in a series of OxCal Bayesian software models to estimate the times of megathrust earthquakes and tsunamis over the past 6700 years. We include code for the OxCal Bayesian software models used to calculate age probability density functions for the lake’s earthquake or tsunami-caused disturbance events, and for the stratigraphic contacts produced by earthquakes and tsunamis at the tidal wetland sites.
