In the Field

Show the PGES field engineers a map of Africa, and ask them to point out where they’ve been.

“I’ve been here”, they’ll say, sweeping a hand from Mali to Ethiopia.


The passive seismic data acquisition transportable array is a local seismic network that records micro earthquakes and then the local response of the background seismic wave field and activity to enable to study the local structure of Earth’s interior over basins. 


PGES’s field engineers have installed only in Africa more than 1200 seismic stations at variable intervals between 500 m up to 4 Km across the most prolific and unexplored basins in extremely remote areas.


Field engineers lie somewhere between stations, four-wheels drive trucks, land cellular service providers and satellite service connections.



They work everywhere and nowhere. They live out of trucks and take-out containers to build data acquisition stations in passive and passive seismic modality. 


They have seen almost every village a less than “5 kilometers” resolution through a dusty windshield along Africa, America, Europe and Asia.


The field crew deploy the data acquisition grid in one area, then remove them in order to re-deploy them elsewhere. 


Reusing the seismic instruments in this way requires a finely tuned schedule of field operations, an immense solving problem attitude, an unusual level of commitment: weeks of travel, hours of carrying supplies between seismic stations in remote locations, passion, dedication and, above all, immense respect for the local people communities  and environment.
