Underground Atomic Test Deep Under Desert Mesa Chamber
A small underground atomic shot planned at an atomic test site aims to reveal Earth’s interior by seismic waves while staying contained. The device, 800 feet below the surface in a chamber at the end of a tunnel, will be fired at 10 am PDT with an estimated yield of 1000 to 3000 tons of TNT. Observers expect minor surface effects. scientists across 600 quake stations will record readings for the International Geophysical Year.
