👈Reuters: The United States carried out an underground non-nuclear chemical explosive test at the Nevada National Security Site to improve detection of low-yield nuclear explosions.

This test focused on identifying “decoupled” explosions, which are harder to detect through seismic monitoring. Washington has accused China of carrying out such a covert test in 2020, an allegation that Beijing denies.

The data from this test will be used to improve scientific models and algorithms for detecting nuclear explosions.
