Use of long-period surface waves for determination of elastic and petrological properties of ice masses
Elastic wave propagation has proved to be a powerful tool in the study of the mechanical properties and thicknesses of ice masses. The anisotropy, heterogeneity, and departure from perfect elasticity that plague conventional static tests can all be studied in detail by seismic techniques that have b...
