Seismology & the Kursk
The main Kursk explosion was so large that it was easily detected on many seismic stations across Europe. The equivalent of a magnitude 3.7 earthquake.
Signals produced by the Kursk explosion are very similar in size to those from a recent underwater calibration explosion in the Dead Sea, which was the equivalent of 5 tons of TNT.
The location of the Kursk explosion was automatically computed and entered into seismic bulletins within a few hours of its occurrence.
Data from these seismic stations is available to anyone via the Internet (though it does take some tools to actually use it).
Continuous data generally available with only a 15-minute lag behind real-time.
Bandwidth of seismic data is generally 20 Hz.
