Nuclear Explosion Location at the Lop Nor test site, China

CORVALLIS, Ore. – A new analysis of satellite data from the late 1990s documents for the first time the “uplift” of ground above a site of underground nuclear testing, providing researchers a potential new tool for analyzing the strength of detonation.

The study has just been published in Geophysical Research Letters.

Lead author Paul Vincent, a geophysicist at Oregon State University, cautions that the findings won’t lead to dramatic new ability to detect secret nuclear explosions because of the time lag between the test and the uplift signature, as well as geophysical requirements of the underlying terrain. However, he said, it does “provide another Read more…
