Tectonic Geodesy
Figure 6. Accumulated plastic strain in logarithmic scale at a cross
section 15 km from the epicenter from a model using a fractal fault
geometry. The curved black line shows the fault trace at this cross
section. The right side of the fault is a extensional regime, where the
plastic strain is larger.
Introduction
The tectonic geodesy community within SCEC has again focused its efforts on inter-related combinations of data gathering
and interpretation. The validation and application of transient detection algorithms was again a major effort, with a wide
range of algorithms being tested against real and synthetic data. We are currently on track to having several detectors running
in a SCEC-supported testing framework before the end of the year.
Transient Detection
Duncan Agnew made his FAKENET software available to the community, both for internal testing of detection algorithms as
well as for the generation of new synthetic test data. Some of the major changes this year allowed inclusion of more realistic,
non-sinusoidal seasonal signals and volume sources that imitate the effects of groundwater withdrawal and recharge. Herring
