  • Radar reveals details of mountain collapse after North Korea's most recent nuclear test
    on May 10, 2018 at 7:00 pm

    North Korea's Sept. 3, 2017, underground nuclear test -- it's latest and biggest -- created a 5.2 magnitude earthquake and 4.5 magnitude aftershock. Researchers combined synthetic aperture radar with seismic measurements to determine that the explosion pushed the mountain surface outward up to 11 feet and left it 20 inches shorter, probably after cavity collapse and subsequent compression of fractured rock. The aftershock may have been a tunnel collapse. […]

  • New instrument identifies unexploded artillery shells
    on December 12, 2017 at 3:57 pm

    Society faces threats through the malicious use of chemical, biological, radiological, nuclear and/or explosive (CBRNE) materials. The detection of illicit trafficking or other criminal acts, as well as many security and safety applications, call for novel material analysis techniques and instruments. These detection systems should be non-destructive but still be able to detect and identify the threat objects, even from inside a shielding or masking enclosure. Active interrogation methods that use penetrative particle beams can reveal the presence of CBRNE materials. […]
