Global Security

Seismological tools help scientists probe the internal structure of the earth, but they have another, national-security-enhancing role, as Livermore seismologist Stephen Myers well knows—they help detect underground explosions.

“Our motivation is to help the U.S. verify the Comprehensive Test Ban Treaty by detecting any nuclear explosive tests that may happen worldwide,” says Myers, program leader for Ground-Based Nuclear Detonation Detection R&D at Livermore.
