Dear all,

We cordially invite you to contribute to our session
TS3.11:
"Earthquake mechanisms: Fluids or stress transfers?" (EDI - ECS)

https://meetingorganizer.copernicus.org/EGU23/session/46237

ABSTRACTS SUBMISSION DEADLINE: 10th January 2023

  • TS3.11 session description:*
    A sound comprehension of earthquake genesis and rupture propagation plays a
    significant part in evaluating seismic hazard. It is crucial to understand
    the processes and conditions causing the initial stages of rock failure at
    depth, and the interplay between mineral- and tectonic-scale processes.
    Both fluid percolation events and transformation-driven stress transfers
    are viable processes which can trigger mechanical instabilities ultimately
    causing rupture nucleation. There is still a lack of understanding
    regarding the exact conditions for earthquake nucleation and dynamic
    rupture propagation, including considerations on fracture mechanics under
    viscoelastic conditions, stress transfers, and/or fluid percolations. While
    observational methods help image mechanical instabilities, laboratory
    experiments provide insights on the physics of the lubrication processes
    enabling seismic faults to grow under pressure. However, there remains a
    significant gap in scientific discourse between the two schools of
    research. Therefore, we aim to bring researchers together to address these
    fundamental questions, opening doors between our respective expertise. This
    session aims to lead a transdisciplinary discussion and trigger unexpected
    collaborations between researchers from diverse fields. We encourage
    contributions from any discipline, including field geology, experimental
    petrology, mineral physics, thermodynamics, seismology, numerical
    modelling, geodesy and magnetotellurics. We will pay particular attention
    to abstracts from early-career researchers. This is an inclusive session
    that won’t accept any discrimination at any stage.

Important meeting information:
The EGU General Assembly 2023 (23-28 April) is announced as a hybrid event.

We look forward to your contributions and hope to see many of you either in
Vienna or online.
Please do not hesitate to transfer this announcement around you. The goal
is to trigger a constructive transdisciplinary discussion involving a
diverse group of researchers.

Best regards,

Thomas P. Ferrand on behalf of all conveners

Conveners:
Thomas P. Ferrand (Freie Universität Berlin)
Lisa Eberhard (Universiteit Utrecht )
Mattia Gilio (Università degli Studi di Pavia)
Revathy Parameswaran (University of Alaska Fairbanks)
