Determine the thickness of the Basalt layer

Synthetic Seismogram’s Def’n

• “An Artificial seismic reflection record manufactured by assuming that a particular waveform travels through an assumed model”

• “A 1D sythetic seismogram is formed by simply convolving an embeded waveform with a reflectivity function”

From E. D. A. G.
