SM4.2 | Using seismic and geodetic data to constrain the spectrum of fault slip behaviours
Using seismic and geodetic data to constrain the spectrum of fault slip behaviours
Convener: Gareth Funning | Co-conveners: Daniel Gittins, Lidong Bie

Slip on faults can occur in several different modes – as earthquake stick-slip, interseismic creep, transient aseismic slip, or postseismic afterslip. Some faults or regions may show multiple of these behaviours, and interactions between them can have important implications for hazards – transients can trigger mainshocks, mainshocks can trigger afterslip, areas of fault creep can act as barriers to fault slip.

We welcome submissions that constrain and investigate fault slip using geodetic data, such as GNSS, InSAR, creepmeters, strainmeters or repeat-pass lidar, using seismic data, through analysis of earthquake waveforms, repeating earthquakes, microseismicity or aftershocks, and/or by models constrained by such data. We are particularly interested in studies that combine diverse data types, that resolve multiple modes of slip on the same fault, and/or that detail interactions between different slip modes.
