Paper on analysis of sequences framing larger events at The Geysers geothermal field

The paper entitled “Analysis of Microseismicity Framing ML>2.5 Earthquakes at The Geysers Geothermal Field, California” by Stephan Bentz from our Section has been finally published in Journal of Geophysical Research: Solid Earth. This is another paper related to the analysis of seismicity at the Geysers geothermal field performed in our section.


In the paper, we statistically analyze temporal properties of seismicity utilizing
seismicity catalogs framing 20 ML>2.5 earthquakes enhanced with the template matching algorithm. We found that triggered aftershocks or larger events are mostly restricted to the northwestern part of the geothermal field and that larger events may be preceded by
isolated smaller earthquakes at approximately the same location.
