Absolute Vibration Levels at Surface Due to Large Dynamite Charges at Depth

P234 ABSOLUTE VIBRATION LEVELS AT SURFACE DUE TO LARGE DYNAMITE CHARGES AT DEPTH Summary 1 In September 2001 a noise test for imaging the lithospheric crust below the Netherlands was carried out. In the late 1980’s TNO shot a 2-D seismic profile through the Netherlands with one aim being to image down to the lower crust but their main target (acquisition parameters) was the upper sedimentary basin and not the crystalline crust down to the Mohorovic discontinuity. Therefore in the noise test large dynamite charges and large offsets (4 km to 32 km) were recorded. However since such large charges
