1) Earthquake source: from the lab to the field
2) Fault structure, hydrology, (a)seismic slip processes

|Our new study casts doubts on
the longterm decay rate of induced
seismicity in Oklahoma and the model used to assess seismic
hazard in a previous study.
Here is our comment, the original paper and response. Here is also a short press release summarizing our findings:

|Do we really know more about induced
than tectonic earthquakes? Our recent paper in JGR showed,
that the maximum
magntiudes of induced earthquakes are as large as expected from
Gutenberg-Richter scaling. This
means that rather than applying a deterministic frame work to induced
earthquakes the same probabilistic framework should be used for
tectonic and induced seismic hazard assessment. More details can be
