How to Detect Humans Under-the-Ground: Surveillance Best

Tunnel-digging in times of conflict has a long history. These days, secret tunnels are used to move weapons and people between Gaza and Egypt, and by Kurdish militia operating on the frontier between Syria and Turkey. But the same principle applies. What happens underground is hard for the enemy to observe. Digging for victory is therefore often a good idea…

That, though, may be about to change. Real-time Subsurface Event Assessment and Detection (RESEAD), a project being undertaken at Sandia National Laboratories in New Mexico, uses novel sensors to make accurate maps of what is happening underground. This will, no doubt, have many civilian applications. But Sandia is principally a weapons lab…The sensors themselves are a mixture of accelerometers, which pick up vibrations, current detectors, which measure the electrical-resistance of rocks and soil, and subsurface radar…

Exactly how RESEAD sensors would be put in place in a zone of active conflict remains to be seen. But the system could certainly be useful for other sorts of security. In particular, America has a problem with tunnels under its border with Mexico being used to smuggle drugs and migrants into the country. RESEAD would be able to detect existing tunnels and nip new ones in the bud.

Zero Radioactive Leakage: China Experiments with Nuclear Waste Disposal

China has chosen a site for an underground laboratory to research the disposal of highly radioactive waste, the country’s nuclear safety watchdog said in September 2019.
Officials said work would soon begin on building the Beishan Underground Research Laboratory 400 metres (1,312 feet) underground in the northwestern province of Gansu, in the middle of the Gobi desert.

Liu Hua, head of the National Nuclear Safety Administration, said work would be carried out to determine whether it was possible to build a repository for high-level nuclear waste deep underground….Once the laboratory is built, scientists and engineers will start experiments to confirm whether it will make a viable underground storage facility…

Lei Yian, an associate professor at Peking University’s school of physics, said there was no absolute guarantee that the repositories would be safe when they came into operation.
Leakage has happened in [repositories] in the US and the former Soviet Union … It’s a difficult problem worldwide,” he said. “If China can solve it, then it will have solved a global problem.”
China is also building more facilities to dispose of low and intermediate-level waste. Officials said new plants were being built in Zhejiang, Fujian and Shandong, three coastal provinces that lack disposal facilities.
