In 1991, geophysicist Thomas L. Dobecki, Boston University geologist Robert Schoch and John Anthony West used seismic refraction to survey the Sphinx. The team reported a rectangular anomaly about 30 by 40 ft beneath the Sphinx, roughly 35 ft below the surface. The result was a geophysical anomaly, not direct confirmation of a chamber or tunnels, and the cited evidence does not substantiate the claim that a 1996 GPR survey confirmed one.
1991 seismic survey found anomaly beneath the Sphinx

Key facts
- Thomas L. Dobecki—not "Tom Dbecki"—conducted the 1991 survey with Boston University geologist Robert Schoch and John Anthony West.
- The 1991 survey used seismic refraction, not ground-penetrating radar, and Dobecki published the results in 1992.
- It reported a roughly 30-by-40-foot rectangular anomaly about 35 feet below the surface beneath the Sphinx.
- The survey recorded a geophysical anomaly, not direct confirmation of an artificial chamber or passages leading toward the pyramids.
- The cited evidence does not establish that a 1996 GPR survey independently confirmed a chamber.
- Zahi Hawass and Mark Lehner disputed the chamber interpretation, citing natural geological features.
