Seismology Data Exposes N. Korea
Jeffrey Park, Bulletin of the Atomic Scientists
A few minutes short of noon, local time, on February 12, an underground blast in a remote corner of North Korea sent seismic waves worldwide, leaving clear recordings on thousands of seismometers. Some of these seismological recorders belong to clandestine intelligence-gathering networks in the service of individual nations. You and I will probably never see the data gathered by these networks, but we don't need to. Primarily to monitor earthquakes within active fault zones, thousands of seismometers around the globe record ground motion and distribute that information to the public.
