Dear Colleagues,

We would like to call your attention to two sessions focused on understanding the physics and modeling of earthquake ground motions at the AGU Fall meeting.

Session S005 will focus on earthquake source physics and its interplay with strong ground motion, including earthquake source physics studies from observational, experimental and theoretical perspectives, constraints on earthquake source physics by ground motion recordings, and simulations of strong ground motions using dynamic source models. Invited speakers include Daniel Roten and Alice Gabriel.

Session S019 will focus on observational, numerical and experimental studies relating to improved strong ground motion modeling, including applications of numerical ground motion simulations; experimental rock mechanics; studies of earthquake source parameters; and modeling of path and site effects. Invited speakers include Hiroe Miyake and Domniki Asimaki.

Abstract submission deadline is August 3.

On behalf of the convenors,
Morgan Moschetti and Benchun Duan


S005. Earthquake source physics and its interplay with strong ground motion
Laboratory experiments and theoretical studies reveal physical processes and mechanisms that result in significant dynamic coseismic weakening. Complex fault geometry and surface roughness have important effects on dynamic rupture propagation and seismic radiation. Off-fault damage contributes to the energy budget of an earthquake rupture, and alters amplitude and frequency content of ground motion. How well do these processes and factors of earthquake sources manifest themselves in strong ground motion recordings? Ground motion simulations of scenario earthquakes have become an increasingly important vehicle for seismic hazard analysis. Incorporating as much source physics as possible into these simulations allows predictions of ground motion to be as realistic as possible. Dynamic source characterization can help achieve this goal. In this session, we welcome contributions that advance our understanding of earthquake source physics, or improve strong ground motion predictions by incorporating more realistic earthquake source physics.

S019. Modeling earthquake strong ground motions
Accurate modeling of earthquake strong ground motions is a critical component of engineering seismology that is required to understand recorded ground motions and to forecast potential ground-shaking. The increasing interest within the earth science and earthquake engineering communities in the use of simulated ground motions for seismic hazard and risk analysis requires a multidisciplinary approach to understanding earthquake rupture and wave propagation. We aim to bring together researchers engaged in observational, numerical, and experimental studies of the earthquake rupture and wave propagation processes. We invite presentations on all topics informing earthquake ground motion modeling, including applications of numerical ground motion simulations; experimental rock mechanics; studies of earthquake source parameters; and modeling of path and site effects.
