“The problem is the utilities don’t have the sensors to know this is occurring. This sensor network is sophisticated and sensitive. We have more information than they do. Our objective, we’ve been trying to get utilities to pay attention to the data because it’s valuable to know when the grid is stressed.”

Now, in a paper published last month in Earthquake Research Advances, researchers report a reanalysis of 2010 seismic data from a sensor network in China that identifies a “small explosion” within 2 kilometers of the 2009 test site.

In their publication, the Innsbruck scientists show that the precision of the sensor measurements increases with the number of particles in the sensor network.

The in-vehicle sensor network developed by FAU researchers in the College of Engineering and Computer Science, uses open-source hardware and software components to reduce the time, risks and costs associated with developing in-vehicle sensing units.

With help from a constellation of government and philanthropic funders who collectively have contributed nearly €750,000, Lima and Seabra are now working with researchers along the Atlantic coast to fill gaps in the sensor network.
