Call for abstract submissions to paleoseismology session at 2024 SSA Annual Meeting

Dear colleagues,

We would like to invite you to submit an abstract for the 2024 SSA Annual Meeting, where we will be organizing a session called “From Faults to Fjords: Earthquake Evidence in Terrestrial and Subaqueous Environments.”

We aim to bring together paleoseismologists from all over the world and across all environments for an inspiring session at the forefront of its discipline. You can find the full session description below.

Abstract submissions are due 10 January 2024 (11:59 PM, PST) or 30 November 2023 if you want to apply for travel support. More information is available via https://meetings.seismosoc.org/submit/.

Please don’t hesitate to spread the word, and submit your abstract to join us in Anchorage, Alaska!

Best regards,

From Faults to Fjords: Earthquake Evidence in Terrestrial and Subaqueous Environments

Strong ground motion and surface deformation caused by slip on plate boundary, intraslab and crustal faults perturb surficial processes and leave geologic evidence in terrestrial and subaqueous environments. This two-part session explores paleoseismic approaches that use geologic evidence to reconstruct records of past earthquakes. Part one will address earthquake evidence in terrestrial settings. This evidence may be produced by coastal, fluvial and colluvial processes that together shape the ultimate sedimentary and geomorphic response to tectonic surface deformation. Presentations also may focus on ground failure and landslides triggered by earthquake shaking. Part two will feature subaqueous lake bottom and seafloor imprints and processes triggered by earthquakes. These earthquake-triggered responses are governed by the properties of the passing seismic waves (frequency, amplitude, duration) and the geomechanics of the substrate (grain size, composition, shear strength). Presentations may focus on the array of subaqueous sedimentary responses to strong ground motion, including different styles of mass failure, surficial sediment remobilization, soft sediment deformation and/or seismic strengthening.

We invite presentations from Alaska and beyond that highlight paleoseismic records from all depositional environments, laboratory analyses, modeling studies, or syntheses and comparisons of global records. We particularly encourage presentations of: 1) Novel techniques using geophysical survey tools, sediment sampling analyses and remote sensing techniques to quantify tectonic deformation; 2) Studies with high geochronological precision, beyond the limitations of typical radiometric dating; 3) Studies that compare paleoseismic records from adjoining subaqueous and terrestrial environments, pointing out the promises and pitfalls of different approaches; and 4) Experiments that simulate the array of surficial processes that form geologic evidence of earthquakes.
