Laurentian University conducting 7-year, $104-million study into structures in earth’s crust
The large trucks seen recently along major roadways in Sudbury are conducting seismic testing. It’s all part of a major research project by Laurentian University.
That seismic testing is not to detect natural or man-induced mining seismic activity, rather the testing is similar to sonar or ultrasound, says Harold Gibson, director of the Metal Earth Project.
The vibration trucks send out seismic waves, which reflect off features in the earth’s crust and then back to receivers or geophones that have been spread out 20 to 30 metres apart. The data is compiled into a seismograph showing 40 kilometres below the surface of the earth. Continue Reading →
