Abstract
The M 6.5 earthquake that occurred in the Monte Cristo Range near Mina, Nevada on 15 May 2020
was exceptionally well-recorded with both seismic and geodetic instrumentation. The arid nature
of the region also facilitated detailed ground mapping of the surface rupture. Here we integrate
several independent data sets to illustrate the educational and research opportunities afforded by
these rich data sets. We construct a series of models for slip at depth that are consistent with the
satellite-derived geodetic data, the distribution of aftershocks, and the mapped surface rupture.
We also show that the modelled depth of maximum slip is in good agreement with heat flow and
laboratory data on quartz rheology defining the depth of the brittle-ductile transition. The Monte
Cristo Range earthquake also suggests new approaches to seismic hazard assessment may be
required for earthquakes in rapidly evolving tectonic regions such as the Walker Lane and Eastern
California shear zone.
