| | 講演要旨(英文) | | Seismic method has been applied all around the world but still has an obstacle for volcanic rock on the surface where there are some conditions that the seismic wave does not propagates as easy as in the clastic sediment. Some significant problems for the conventional explosive seismic source like dynamite are how to make a shot hole drilling for the dynamite and the absorption of the seismic energy. These problem make the seismic data does not give good subsurface imaging for interpretation. Vibroseis as an alternative seismic source on the surface was tested over the volcanic rock could make enough energy for the seismic wave to propagates down to earth and back to the surface. The main parameter for vibroseis sweep and type receiver were tested over 2D seismic line near by Mount Ciremai at West Java and gave better result in subsurface imaging compare to the explosive seismic source. |
