Registration of the third North Korean nuclear weapon test (Feb. 12, 2013)

The Democratic Peoples Republic of Korea has according to reports of international media and the Comprehensiv test ban treaty organisation (CTBTO) committed an underground nuclear weapons test on Feb. 12., 2013 at ca. 12:00 local time (3:00 UTC). This created a seismic event of magnitude M=5.2 (Quelle: BGR). The seismic waves arrived after ca. 11 minutes and 36 seconds the seismic stations of the Seismmological Observatory of the Ruhr-University Bochum at a distnace of ca. 7500 km. The seismogramms clearly show the arrival of the seismic wave at the stations (s. figure). The shown stations are in Ibbenbüren (IBBN), at Haltern in the area of the Mine Auguste Victoria (BAVN), at the Technical Centre of Ruhr-Universität (BTEZ), in the State Language Institute (BULI), on the camputs of the Ruhr-University (NABF), the historic mines of Klosterbusch (BUG und BKLB) and Pfingstblume (BPFI, all three close to the Ruhr-University) and at the Mine Prosper Haniel at Hünxe (ZER3).

The Ruhr-Universität Bochum monitors the seismicity of the Ruhr coal mininig district since 1981. The seismic network currently consits of 16 stations, which are located in the Ruhr area.
