The same way we can detect an earthquake is how we detect an underground nuclear test. Basic atmosphere equipment can detect the sudden temperature change.

Who has instruments close by to detect a minor underground explosion deep in North Korea? And what basic atmosphere instruments are you referring to? And who was operating them over south Korea at this exact time?

Satellites pick up the temperature changes and we have sizemoligy(sp?) equipment in South Korea along with 35,000 troops assigned to monitor NK, EP-3 spy planes are also quite handy in that area

"minor underground explosion"

A weak and minor atomic bomb, like the one we dropped on Nagasaki is more powerful than all the conventional bomds dropped by the allied forces in WWII. The Hydrogen bombs of today are 1,000 times stronger than the one dropped on Nagasaki.

There is no such thing as a minor nuclear explosion

I think Japan would. They need to monitor their earthquakes.

Japan is an active seismic zone and has a topnotch monitoring network.
