December 2019 experiment

We performed a complementary pilot dense array experiment aimed at testing noise-based seismic monitoring of the San Jacinto fault in Southern California (UGA/ISTerre, UCSD/IGPP, USC). It aimed at testing new sites following our results of train noise correlations (see publications).

It consisted in the deployment of 4 arrays for a total of 100, 5 Hz, 3-components seismic stations during just a few days from 1 to 5 December 2019. The data were recorded at 500 Hz (2 ms).

Errors up to 15° can be found in the horizontal sensors orientation. Most of the stations should be oriented towards the geographical North. (1201 to 1212 are possibly oriented towards magnetic North, to be checked, ~10° difference).

The main network page for the FaultScan experiment is here:

It is also possible to use the PH5 web services, http://service.iris.edu/ph5ws/ to

verify the metadata and data availability if you haven't already done so.
