|Van Avendonk is an active-source seismologist who specializes in the acquisition and inversion of seismic refraction data on land and at sea. Often these seismic refraction data are used for a tomographic inversion. The resultant seismic velocity models help us to interpret the composition of the Earth’s crust and ...|
