WebSEP86. intro In September of 1988, the Stanford Exploration Project (SEP) conducted a passive seismic experiment. In a remote area of the Stanford campus, 4056 geophones were set out in a two-dimensional array. Ambient seismic energy was recorded over an eighteen hour period. Several factors motivated us to perform such an experiment. WebSISPROBE offers a full range of solutions to challenges in seismic survey design, seismic data acquisition, processing and interpretation, exploration, exploitation, mine safety, …
