A simple model to show the influence of fluid flow in the fault zone on patterns of seimicity

1. Fluid flow and seismicity some ancient history Jeremy Henderson

2. Motivation – understand the influence of the physical processes on the geometry seismic b -value fractal dimension of earthquake epicentres

3. Data from Geysers geothermal area, California Is there a correlation?? … maybe …

4. A simple numerical model

6. Modelling procedure

7. Lattice evolution - snapshots broken elements high fluid pressure low fluid pressure

8. Results ” permeability relative to compaction”

10. End
