People may misunderstand the use of thermobaric explosives on underground tunnels. First, penetrate the layers of the tunnels to open them up and expose various levels, then set off thermobaric explosives that will suck all the air out of the exposed tunnels.

Most of those in the tunnels will suffocate within minutes due to lack of oxygen. There may be a few isolated pockets of survivors, but not many.

Meanwhile, some of the records, computers, lab data can be preserved for later investigation.
