The survey described here was conducted by LA Seismic using the Fairfield Node System on behalf of BreitBurn Energy. We thank Henry Biggart of Geokinetics for providing vibrator sources for the survey. The target is the Rosecrans oilfield in southern Los Angeles, CA. The survey was done July 28 - August 27, 2013, and consisted of approximately 2000 sensors.

The black lines indicate mapped faults. The fault traversing the survey is the Newport-Inglewood Fault Zone (NIFZ). | |
Here is a movie that shows the deployment of the Rosecrans recording array.
Rosecrans Deployment
We thank BreitBurn Energy for permission to use the Rosecrans data, and
LA Seismic for supplying it. The research is supported NSF/EAR-1214912
and a grant from the THOR project.

The above table is a list of earthquakes from the CISN catalog for this region during the survey.
The column 'Num' refers to the earthquake label in the above plot. The ID is the SCSN id for
the event. The last column is a link to an mpg movie of the event.
Correlations with SCSN
The data from the Rosecrans array were correlated with the neighboring SCSN
stations as part of a project to extend the analysis into the Los Angeles Basin.
They were collected in a master time versus of profile by stacking. Correlations and figiures by Zhe Jia.
