In addition to the routine operations and
maintenance of the HRSN (California's first
and longest operating borehole seismic network),
research into: 1) how to process ongoing similar
and repeating seismicity to very low magnitudes,
2) ongoing non-volcanic tremors in the
Parkfield-Cholame area, 3) SAFOD related
activities and 4) various approaches to lowering
operational (primarily landowner fee) costs
have been the primary driving
forces behind most of the HRSN project's
activities this year.
