Vienna, 13 July 2017

In response to recent media reports, the CTBTO confirms that its International Monitoring System (IMS) stations are functioning normally. The seismic event that was detected in the Sea of Japan on 12 July around 19:48 UTC shows all indications of being a natural event. This is an area of relatively low seismicity South of Vladivostok in the Russian Federation and off the coast of the Democratic People's Republic of Korea (DPRK). The event was initially detected by 46 of CTBTO's stations, including infrasound station IS45 in Ussuriysk (RF) which registered a P-wave seismic signal (not an infrasound wave). It had a calculated magnitude of 5.3 and occurred at a depth of around 550 km.

The CTBTO has established a global network of stations that use four complementary technologies to monitor the globe 24/7 for signs of a clandestine nuclear explosion. For more, please see: https://www.ctbto.org/verification-regime/
