The main efforts of this research lab are
devoted to the understanding of the kinematics and dynamics of crustal
deformation in (diffuse) plate boundary zones. The kinematics teach us about
the dynamics, and vice versa.
Kinematic studies are aimed at obtaining
velocity and strain rate tensor field estimates within areas of deformation,
inferred from Quaternary fault slip rates, earthquake moment tensors, and
geodetic data. Special focus is on how and where plate motions are accommodated
within areas of diffuse deformation, the relationship between long-term and
short-term deformation rates, and the interpretation of the results in terms of
seismic hazard.
Dynamic studies are aimed at the
investigation of the driving forces of crustal deformation in the western United States and Asia. The
absolute contributions to the regional stress field of plate interactions and
gravitational potential energy differences are estimated.

Holt & Bingming
Shen-Tu
- A
New No-Net-Rotation Model

Holt & Corné Kreemer
Past studies performed in
this lab were aimed at understanding deformation in New Zealand, Indian Ocean, Japan, and the Explorer
plate region (off-shore Vancouver
Island).
If you would like to see
movies of large-scale deformation that we have created in this lab, please go here
. There are examples of Asia, California, New Zealand, and Pakistan.
A nice overview of the
current work on crustal deformation in this lab can also be found on the UNAVCO website.
