We’d like to draw your attention to our interdisciplinary EGU session (co-sponsored by AGU), which seeks to deepen our understanding of the variety of slip behaviours through a diverse set of topics and methodologies. We hope you will consider submitting an abstract! Please feel free to share this with anyone else who might be interested.
Deadline for submission: January 15, 2020
Session TS5.4/GS9.4/SM2.9:** Seismic and Aseismic Slip on Seismogenic Faults**
Chris Marone (Penn State & Sapienza University of Rome): “Fault healing plays a key role in creating the spectrum of tectonic faulting styles from seismic to aseismic slip”
Adriano Gualandi (Caltech): “Towards Slow Earthquakes Forecasting”
Tectonic faults accommodate plate motion through various styles of seismic and aseismic slip spanning a wide range of spatiotemporal scales. Understanding the mechanics and interplay between seismic rupture and aseismic slip is central to seismotectonics as it determines the seismic potential of faults. In particular, unraveling the underlying physics controlling these styles of deformation bears a great deal in earthquakes hazards mitigation especially in highly urbanized regions. In partnership with the AGU Tectonophysics section, we invite contributions from observational, experimental, geological and theoretical studies that explore the diversity and interplay among seismic and aseismic slip phenomena in various tectonic settings, including the following questions: (1) How does the nature of creeping faults change with the style of faulting, loading rate, and other factors? (2) Are different slip behaviors well separated in space, or can the same fault areas experience different failure modes? (3) Is there a systematic spatial or temporal relation between different types of slip?
