Earthquakes: Nucleation, Triggering and Relationships with Aseismic Processes - 3rd Edition

Organisé par Anthony Sladen

Earthquakes remain unpredictable, despite decades of intense investigations into possible precursory phenomena. The main difficulty lies in our incomplete knowledge of the state of stress on active faults at seismogenic depths, and a full understanding of how rupture initiates and stops in a complex medium characterized by a variable stress field acting on complex fault geometries.

In the last decade, however, great advances have converged towards a much more complete picture of earthquake-related processes. The quality and quantity of seismic data, as well as their diffusion to research scientists through open-data policies, have been much improved, most recently owing to the development of very dense and / or very sensitive seismic networks, and a gain in location accuracy; the ubiquitous nature of aseismic slip has become apparent; and recent mega-thrust and continental earthquakes have provided the seismological community with very rich datasets that help illuminate possible relationships between seismic and aseismic processes
