BBC reports on asteroid fly-by and the CTBTO’s monitoring stations capability to monitor meteor strikes

eeeBBC reports on a 325 metre-wide asteroid that passed close to Earth on Monday 26 January. It highlights the infrasound IMS stations of the CTBTO which, apart from monitoring nuclear explosions, can also detect meteor strikes.

“The Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) operates a network of infrasound detectors around the globe.

The network counted 26 major explosions between 2000 and 2013, ranging in energy from one to 600 kilotons. By way of comparison, the bomb that destroyed the Japanese city of Hiroshima was a 15-kiloton device.
