The U.S. carried out a non-nuclear underground chemical explosive experiment at the Nevada National Security Site to improve detection of low-yield nuclear blasts.

The test focused on detecting “decoupled” explosions, which can be harder to identify through seismic monitoring. Washington has accused China of conducting such a secret test in 2020, a claim Beijing denies.

Data from the experiment will be used to improve scientific models and nuclear explosion detection algorithms.
