Earthquake Spectra (2023)
doi:10.1177/87552930231205871 PDF
1. A new surface-rupture-length (SRL) relationship
2. Use both empirical and physics-based surface rupture datasets
3. Favor the model that the average displacement is propoportional to square root of rupture area
Chen Ji, Ralph J. Archuleta, Yongfei Wang
Bulletin of the Seismological Society of America (2022)
1. Δσs estimated using the conventional M0 & fc methods strongly depend on the particular theoretical spectral model
2. Model-dependent variability of spectral estimates of Δσs can be largely reconciled using radiated energy ER
3. Robust stress drop estimates are important for seismological studies and engineering applications
Yongfei Wang, Christine A. Goulet
Bulletin of the Seismological Society of America (2021)
This paper is featured as one of the key papers for understanding the 1992 Landers earthquake
1. We propose a process for predicting fault displacements using dynamic rupture modeling
2. We compare a dynamic rupture model against observations from the Landers earthquake
3. The results show promise for using dynamic rupture models of fault displacements in probabilistic assessments
Yongfei Wang and Steven M. Day
Journal of Geophysical Research-Solid Earth (2020)
1. Off-fault plasticity reshapes directivity pulses by reducing peak velocity and increasing dominant period
2. Yielding causes peak ground velocity to saturate with respect to increases in both stress drop and epicentral distance
3. Off-fault plasticity suppresses the high-frequency fault-parallel pulses that otherwise develop when rupture breaks free surface
Yongfei Wang, Steven M. Day and Marine A. Denolle
Journal of Geophysical Research-Solid Earth (2019)
1. Dynamic rupture model isconsistent with the 2015 Gorkhaearthquake slip‐pulse duration andpropagation speed
2. Time‐dependent features of theGorkha earthquake are influencedby rupture geometry andfree‐surface reflections
3. Constraints from near‐field GPSrecording imply no significantrupture of a shallow ramp
Yongfei Wang and Steven M. Day
Journal of Geophysical Research-Solid Earth (2017)
1. Corner frequency changes incrack-like and pulse-like models
2. Stress drop estimate varies withsource characteristics
3. Double spectral decay slopes
