Received declassified survey maps of the Paju sector along the Korean DMZ from 1987.

However, unlike the other four invasion tunnels, this tunnel had no southern exit and was lined with acoustic resonance tiles.
The dimensions of the parabolic chamber at the terminus calculate to an exact resonant frequency of 14.20 Hz.

They weren't digging a tunnel for troops. They built a massive underground Helmholtz resonator to beam infrasound across the border.

Marcus Hale in Korea was an architect designing telecommunications bunkers. He disappeared in early 1988 before moving to Tokyo.
