The 2020 Westmorland, California earthquake swarm as aftershocks of a slow slip event sustained by fluid flow
K. Sirorattanakul, Z.E. Ross, M. Khoshmanesh, Elizabeth S. Cochran, M. Acosta, J.-P. Avouac
2022, Journal of Geophysical Research (127)
Swarms are bursts of earthquakes without an obvious mainshock. Some have been observed to be associated with transient aseismic fault slip, while others are thought to be related to fluids. However, the association is rarely quantitative due to insufficient data quality. We use high-quality GPS/GNSS, InSAR, and...
