Nuclear Testing
China has conducted all of its nuclear weapons tests at Lop Nur, and to date has tested a total of 45 nuclear weapons. 23 of these were atmospheric and 22 were underground. Their sizes range in yield from ~1 kiloton to ~4 megatons. China's most recent test was conducted on July 29, 1996 with a yield of ~1 to 5 kilotons.
Waveform images of the most recent Chinese nuclear tests as recorded by the KNET seismic array
- June 8th 1996 nuclear test, magnitude 5.9 (filtered)
- July 29th 1996 nuclear test, magnitude 4.9 (filtered)
The KNET seismic array has recorded several earthquakes in China since its installation. The following event (nuclear test?) has it's own own dedicated web page:
