Sunday’s underground explosion resulting from the hydrogen bomb created a magnitude 6.3 tremor, which was picked up more than 5,000 miles away by Fulneck School’s seismometer .
The school’s head of physics Dr Caroline Neuberg said: “What I find amazing in this sad event is how small the world is, and that such an occurrence on the other side of the world can be detected by such a physically simple mechanism.
“Over the years, our seismometer has detected events all over world, including Nepal’s 2015 devastating earthquake.
“Sadly, this is the first time we have recorded a tremor caused by the testing of a nuclear weapon.”
