SSA Conference Session

Session TBD – Frontiers in Earthquake and Tsunami Science - Model Integration, Recent Advances, Ongoing Questions

19-23 April 2022 (Bellevue, Washington, USA)

Conveners: Andrea Hawkes, Diego Melgar, Lydia Staisch, SeanPaul La Selle, Jason Padgett

Session details: Over the last several decades, the subduction zone science community has accumulated a wealth of geophysical and geological data on earthquakes and tsunamis. This has enabled the creation of more realistic and diverse numerical models of earthquake and tsunami hazards. However, critical questions about earthquake rupture characteristics, tsunami inundation extents, paleoseismic proxies and more remain unresolved. In this session we solicit presentations on recent advances in modeling earthquake rupture scenarios with particular focus on the use of iterative modeling across coseismic deformation and resultant tsunami inundation. Modeling studies incorporating real-time, historic or reconstructed data constraints (geophysical and/or geological) are expressly welcome.  In this session we hope to highlight advances in the field of earthquake and tsunami science and outline the steps needed to move towards more integrated models and filling important knowledge gaps. Such gaps may include limited geologic and/or geophysical data constraints, needs for improved modeling methodology, etc. We hope participants view this session as a community discussion on continued improvement of earthquake and tsunami science.

Session NH5.3 – Geological Records of Tsunamis and Other Extreme Waves

3-8 April 2022

Conveners: Ed Garrett, Jessica Pilarczyk, Max Engel, Simon Matthias May, Dominik Brill

Session details: Tsunamis and storm surges pose significant hazards to coastal communities around the world. Geological investigations, including both field studies and modelling approaches, significantly enhance our understanding of these events. Past extreme wave events may be reconstructed based on sedimentary and geomorphological evidence from low and high energy environments, from low and high latitude regions and from coastal and offshore areas. The development of novel approaches to identifying, characterising and dating evidence for these events supplements a range of established methods. Nevertheless, the differentiation between evidence for tsunamis and storms still remains a significant question for the community. Numerical and experimental modelling studies complement and enhance field observations and are crucial to improving deterministic and probabilistic approaches to hazard assessment. This session welcomes contributions on all aspects of paleo-tsunami and paleo-storm surge research, including studies that use established methods or recent interdisciplinary advances to reconstruct records of past events, or forecast the probability of future events.
