Session Description:

The complexity of earthquake rupture and the parameters that control such behavior is an active area of investigation that includes many challenging research topics. This session will highlight recent advances in rupture dynamics on complex fault systems and their comparison with different types of available observations. We are interested in a wide range of investigations related to numerical, experimental and observational fault rupture studies that examine the effects of fault geometry, fault roughness, frictional parameters, topography, creeping mechanisms, stress asperities, off-fault material properties and plasticity, bi-material interfaces and wedge structures along subduction zones. We also encourage contributions on research that explores links between earthquake source physics, tsunami generation/propagation and ground motion variability.

Description: Earthquakes and explosive sources can produce complex wavefields and fracture patterns via nonlinear properties and initial conditions (geometry and material).  Additionally, near-source properties such as the pre-stress regime, material strength, frictional processes, anisotropy, topography, and other heterogeneities can add to that complexity in nonlinear and unintuitive ways.  Such properties can affect the nonlinear deformation during an event, impacting the resultant ground motion, plastic deformation, fracture distribution, spall, and the generation of seismic waves seen beyond the nonlinear volume.  Determining the cause-and-effect relationships between earthquake and explosion source media properties and observations is an area of active and challenging research.  This session is intended to highlight recent advances in our understanding of nonlinear dynamics for fault and explosive sources.  We are open to a wide range of studies related to numerical, experimental, and observational findings that may include heterogeneities in source geometry, pre-stress regime, topography, and material properties.  Numerical models that feature algorithms (single or coupled) to robustly model nonlinear time-dependent source properties (e.g., frictional processes, high frequency waves, initial pressure pulses, and fracturing) and their effects are especially welcome.  We also encourage contributions from research topics that explore impact, volcanic, nuclear, and chemical explosive sources.

We look forward to meeting with you,

4. What Controls the Style of Fault Slip in Subduction Zones?

--------------------------------------------------------------------------------------------

We would like to invite you to submit an abstract to the SSA 2022 session “What Controls the Style of Fault Slip in Subduction Zones?”.  
The annual meeting of the 2022 seismological society of America will be held on 19-23 April in Bellevue, Washington. This will be a fully in-person conference with all presenters required to attend on-site. The abstract deadline is 12 January 2022 at 5 p.m. Pacific. You may submit the abstract via this link: (https://meetings.seismosoc.org/submit/).  

Session Title: What Controls the Style of Fault Slip in Subduction Zones? 

The heterogeneous structure of the plate boundary fault zone has a first-order impact on the style of fault slip that occurs at the subduction interface, both within the megathrust and neighboring regions of the seismogenic zone where slow earthquakes occur. For example, subducting seamounts appear to control the segmentation of the megathrust; at a smaller scale, tremor-generating seismic asperities are spatially stationary across multiple slow slip events that each have their own unique rupture evolution. Other controls on structure such as lithology, elevated pore fluid pressures and changing stress states can also play a role in determining faulting style. The outstanding question we would like to address is: what is the impact of subducting plate interface structure on the broad spectrum of faulting that is observed? 

We seek abstracts that shed light on the impact of such fault structure (including but not limited to heterogeneity, lithology, pore fluid pressure and stress state) on the mode of fault slip. We welcome abstracts focused on individual aspects of structure and faulting dynamics, including but not limited to geophysical imaging, earthquake source, and numerical modeling studies, whose connections will be explored within the greater context of the session. Our hope is that this session will build off of, and contribute to, the momentum surrounding the community-driven Subduction Zones in 4 Dimensions (SZ4D) initiative.

5. Advances in Earthquake Geology 

--------------------------------------------------------------------------------------------

Please consider submitting an abstract to our session  "Advances in Earthquake Geology: Spatiotemporal variations in fault behavior from geology and geodesy" at the 2022 Seismological Society of America annual meeting, which will be held in Bellevue, WA from April 19-23. We welcome contributions from field studies, remote sensing/geodesy, or modeling (numerical/analog) that address patterns and variability of earthquake rupture and recurrence.
Abstracts are due on January 12 at 5 PM Pacific time. Submit an abstract here:  https://meetings.seismosoc.org/submit/

Session Description: 

Field and remote sensing observations of recent ruptures at the Earth’s surface highlight variable rupture geometries, surface slip distributions, zones of distributed or off-fault deformation, and fault zone damage. The extent to which these complex and heterogenous patterns are consistent or variable between earthquakes is a fundamental question in earthquake science and remains largely unknown. Meanwhile, advances in numerical and analog modeling and laboratory experiments expand our ability to study strain accumulation and release and the landscape response through multiple earthquake cycles. Additionally, advances in geochronology allow us to better constrain earthquake timing and slip rates, enabling higher resolution comparisons of spatial and temporal patterns of slip within a fault zone. In this session, we encourage abstracts that investigate spatial and temporal patterns (including their causes and uncertainties) in strain accumulation and release spanning coseismic to geologic timescales to address questions such as: (1) How variable or consistent are patterns of surface slip and distributed deformation from one earthquake to the next and along ruptures? (2) How do we infer geologic rates based on limited geodetic records? (3) How does earthquake timing and recurrence cluster through space and time? (4) Are observations from single events representative of earthquake and fault behavior over geologic timescales? (5) How applicable are observations and findings across fault systems? We welcome contributions that present new observations or theories on the patterns and variability in earthquake rupture from field (paleoseismology, tectonic geomorphology), remote sensing (geodesy), or modeling (numerical or analog simulations or laboratory experiments) studies in any tectonic setting that will further our understanding of fault behavior over modern to geologic timescales.
