Data Products from the Berkeley Seismology Lab
Tracking the earth’s noise over time in a certain area allows researchers to explore changes in Earth's structure as the seismic velocity changes, which are related to earthquakes and volcanic eruptions.
You can access daily seismic velocity monitoring for South Napa from just after the August 2014 quake to the present.
BSL scientist Taka'aki Taira's seismic velocity was work highlighted on the SpringerOpen blog
The BSL computes finite fault solutions, which describe the 3-D shape of a rupture, for major events in Northern California.

The Berkeley Seismological Laboratory has been routinely estimating the seismic moment tensors of earthquakes in northern California since 1992. These moment tensors are mathematical descriptions of the forces that drive earthquake rupture.

The TremorScope stations are designed to record recently discovered deep tremor along the San Andreas Fault in central California. Early studies reveal fascinatingly complex faulting behavior in the deep crust that is surprisingly different from "normal" earthquakes in the upper crust and help improve our understanding of fault mechanics and earthquake hazard.
