Did anyone expect it to be?
Not really and I don't think NDT really does either, he's using pop sci-fi for science outreach to point out the parts of the fiction that are fiction that many of us without a thorough science education may miss or to build interest for science in the general population. I think even if he misses the mark sometimes it's a valuable thing to attempt and he does nail it occasionally.
The guy whonwas in the superman movie?
Seismic surveys looking for oil and gas use what's called a thumper truck, which literally thumps the ground to send seismic signals through the Earth. Those signals are received by seismometers some distance away. Geologic structures underground are detected by the way they reflect, bend and otherwise change the thumper truck's seismic waves.
When seismologists perform these surveys near sand dunes, however, they notice their signals are not coming through clearly.
