Dear colleagues,

Please consider submitting your work to the following *EGU 2019*session
by*Thursday, 10 January 2019*, 13:00 CET to join a great
interdisciplinary discussion of observations and modeling!

*Crucial characteristics of earthquakes that generate tsunamis from
geologic observations and numerical models*
TS5.5/NH4.19/SM2.11

Tsunamis can be devastating consequences of earthquakes at subduction
zones. Earthquake-generated tsunamis are the direct effect of seafloor
displacements, but how source characteristics influence the magnitude
and shape of these displacements is the topic of much current research
and debate. The keys to advancing our understanding of these phenomena
are both observations and numerical models of earthquake sources across
a range of subduction zones. For example, unexpectedly large slip was
observed during the 2011 Tohoku-Oki earthquake, and one explanation
suggested by numerical modeling is plastic deformation in the wedge.
This has led to re-investigations of the geology of other subduction
zones and the conditions that can lead to large slip at the trench. In
this session, we equally welcome contributions from:
   - observational studies (i.e., seismic surveys, geological
investigations, buoy and satellite data studies),
   - numerical modeling studies of tsunami and subduction zone
processes over a range of temporal and spatial scales (i.e., geodynamic,
seismic cycling, earthquake rupture, wave propagation modeling), as well
as coupled models.
We also encourage the submission of studies that integrate observations
and models and/or provide a comparison. We look forward to research that
targets tsunamigenic earthquakes over a range of timescales, including
work focused on, but not limited to, the influence of megathrust and
accretionary wedge geometry, splay faulting, fluid cycling, and sediments.

*Looking forward to seeing you in Vienna,
