1. Fault Mechanics and Rupture Characteristics from Surface Deformation
----------------------------------------------------------------------------------------------------------

Dear colleagues,
Please consider submitting an abstract to our SSA session, described below. The deadline for abstracts is January 11th.

Title: Fault Mechanics and Rupture Characteristics from Surface Deformation

High-quality surface data (e.g. point clouds, digital elevation models, and digital imagery) have become more readily available and easier to process and analyze with advances in acquisition technologies and computer processing capabilities. Accurate renditions of co- and post-seismic surface deformation permit characterization of fault and damage zone properties at scales and resolutions that were not previously possible. This session addresses advances in earthquake and fault science using the newest generation of digital imagery and topography data. We encourage submissions that use continuous surface data (e.g. lidar, structure-from-motion, InSAR, UAVSAR, pixel tracking) to study fault mechanics and properties, including damage zone width and asymmetry, near and far-field displacement fields, shallow slip deficit, and scarp morphology and degradation.

Many thanks,

Session Description

Earthquakes occur with great spatio-temporal variability, which emerges from the complex interactions between them. Significant progress is being made towards understanding spatio-temporal correlations, scaling laws and clustering, and the emergence of seismicity patterns. New models being developed in statistical seismology have direct implications for time-dependent seismic hazard assessment and probabilistic earthquake forecasting. In addition, the increasing amount of earthquake data available on local to global scales provides new opportunities for model testing.

This session focuses both on recent insights on the physical processes responsible for the distribution of earthquakes in space and time, and on new models and techniques for quantifying the seismotectonic process and its evolution. Particular emphasis will be placed on:

- physical and statistical models of earthquake occurrence;
- analysis of earthquake clustering;
- spatio-temporal properties of earthquake statistics;
- quantitative testing of earthquake occurrence models;
- implications for time-dependent hazard assessment;
- methods for earthquake forecasting; and
- data analyses and requirements for model testing.

3. Varied Modes of Fault Slip and their Interactions – Slow Earthquakes, Creep to Mega Quakes
----------------------------------------------------------------------------------------------------------------------------------------

Dear colleagues,

I would like to draw your attention to the special session on the wide spectrum of fault slip. Please consider submitting an abstract to the session.

Varied Modes of Fault Slip and their Interactions – Slow Earthquakes, Creep to Mega Quakes

Faults show a diverse mode of slips from slow earthquakes, shallow creep to supershear rupture and damaging fast megathrust earthquakes. Slow earthquakes appear to play an important role in the seismic cycles of major faults. They typically occur at the edges of the seismogenic zone, and radiate seismic energy in the form of tremor, low and very low frequency earthquakes. Slow slips are often inferred to be the driving mechanism of migrating swarms of regular fast micro-earthquakes. Regular earthquakes including large damaging megathrust quakes, on the other hand, seem to show different source characteristics. How these different modes of fault slip operate and interact remains an enigma. In addition, frictional properties that control these modes are poorly understood. We invite abstracts on the diverse behavior of fault slip including but not limited to slow slip, tremor, low and very low frequency earthquakes, aseismic slip, fault creep and fast megathrust earthquakes. Multidisciplinary studies incorporating observations and modeling focusing on the mechanism and interactions of different modes of fault slip are encouraged.
