estimates of earthquake source parameters, such as stress drop and radiated seismic …

Large earthquakes and creeping faults

RA Harris - Reviews of Geophysics, 2017 - Wiley Online Library
Faults are ubiquitous throughout the Earth's crust. The majority are silent for decades to
centuries, until they suddenly rupture and produce earthquakes. With a focus on shallow …

Investigating uncertainties in empirical Green's function analysis of earthquake source parameters

RE Abercrombie - Journal of Geophysical Research: Solid …, 2015 - Wiley Online Library
I use a well‐recorded earthquake sequence to investigate the uncertainties of earthquake
stress drops calculated using an empirical Green's function (EGF) approach. The …

Strong correlation between stress drop and peak ground acceleration for recent M 1–4 earthquakes in the San Francisco Bay area

DT Trugman, PM Shearer - Bulletin of the Seismological …, 2018 - pubs.geoscienceworld.org
Theoretical and observational studies suggest that between‐event variability in the median

Does earthquake stress drop increase with depth in the crust?

RE Abercrombie, DT Trugman… - Journal of …, 2021 - Wiley Online Library
We combine earthquake spectra from multiple studies to investigate whether the increase in
stress drop with depth often observed in the crust is real, or an artifact of decreasing …

Variability of earthquake stress drop in a subduction setting, the Hikurangi Margin, New Zealand
