At the invitation of Dr. Andrew Schaeffer (Geological Survey of Canada, Natural Resources Canada), Dr. François Lavoué (UGA) presented the PACIFIC work on the use of seismic signals generated by trains for passive seismic imaging and monitoring on May 5th, 2021. The presentation provided an overview of the activities carried out within the framework of both the PACIFIC and FaultScan EU-funded projects.

The presentation was attended by around 40 people. Technical questions revolved around the parameters controlling signal amplitude, and a more general debate took place on the merits of excluding signals generated by trains from "classic" ambient noise datasets, as is done for earthquakes.
