BIDS Alum – Data Science Fellow

Real name: 
Robert M. Nadeau

I study repeating micro-earthquakes (REQs) and non-volcanic tremor (NVT), which are two recently discovered low-amplitude seismic phenomena that occur in large numbers and have special properties that illuminate deep fault zone and large earthquake processes. In California, they have been identified in only a few select locations, and my current research is focused on obtaining a larger-scale view of their distribution in space and time along the San Andreas Fault in Northern California. This research is laying the groundwork for future in-depth investigations into REQ and NVT processes, how they respond to active tectonics, and how to use these phenomena to better understand changes in fault zone properties preceding larger earthquakes. My use of the large volumes of digital seismic data that have recently become available to evaluate low-amplitude signals requires the development of a big data approach, an effort greatly benefitting by my participation in BIDS.
