Accounting for uncertain fault geometry in earthquake source inversions--II: application to the M w 6.2 Amatrice earthquake, central Italy

Our understanding of earthquake sources is limited by the availability and the quality of observations and the fidelity of our physical models. Uncertainties in our physical models will naturally bias our inferences of subsurface fault slip. These …

Imaging rapid early afterslip of the 2016 Pedernales earthquake, Ecuador

High-Rate (HR) GPS time series following the 2016 Mw 7.8 Pedernales earthquake suggest significant postseismic deformation occurring in the early postseismic period (i.e. first few hours after the earthquake) that is not resolved with daily GPS time …

Unravelling the contribution of early postseismic deformation using sub-daily GNSS positioning

After large earthquakes, parts of the fault continue to slip for days to months during the afterslip phase, a behaviour documented for many earthquakes. Yet, little is known about the early stage, i.e., from minutes to hours after the mainshock. Its …

Accounting for uncertain fault geometry in earthquake source inversions--I: theory and simplified application

The ill-posed nature of earthquake source estimation derives from several factors including the quality and quantity of available observations and the fidelity of our forward theory. Observational errors are usually accounted for in the inversion …

Supercycle at the Ecuadorian subduction zone revealed after the 2016 Pedernales earthquake

Large earthquakes are usually assumed to release all of the strain accumulated since the previous event, implying a reduced seismic hazard after them. However, long records of seismic history at several subduction zones suggest supercycle behaviour, …
