G51C:
Plate Motion, Continental Deformation, and Interseismic Strain Accumulation II

Submit an Abstract to this Session



Session ID#: 30633

Session Description:
Space geodetic data, geophysical and geologic observations and models constrain how plate motion is being taken up by continental deformation and how elastic strain accumulates between earthquakes.  We invite geodetic, (e.g., GNSS, InSAR, VLBI, etc) and geologic and geophysical studies (e.g., fault slip rates, seismicity, and marine magnetic anomalies) that characterize stable plate interiors, plate boundary zone deformation and interseismic strain accumulation. New efforts using modern cyberinfrastructure and open software are particularly welcome. Can elastic strain buildup be readily related to future great earthquakes?  What fraction of plate motion is taken up by fault slip during earthquakes, and what fraction becomes part of distributed deformation off the major faults?  How does fault slip inferred from paleoseismology add up to present-day plate motion?  How fast are mountains currently rising?  To what degree do postseismic transients perturb the nearly constant velocity of the plates and influence the definition of Earth's reference frame?
