The search for an underground nuclear test (Physics Today)

Report by Physics Today’s David Kramer on the recent large-scale on-site inspection exercise in Jordan.

“Did the nation of Maridia secretly detonate a nuclear device? That was the question that Alluvia posed to the Comprehensive NuclearTest-Ban Treaty Organization after the CTBTO’s international monitoring system detected an ambiguous seismic event originating in Maridia. Alluvian officials’ suspicions led them to request that the CTBTO perform an on-site inspection.The Vienna- based organization quickly mobilized a team of dozens of experts to search for more conclusive evidence of an underground test.”

The inspection team set up a base of operations in Jordan. Behind the tents are some of the containers used to transport 150 tons of instruments and other equipment for the field exercise.
