Random thought: this might be something for people with seismomometers
and microbarographs to watch for.  Also, IIRC, explosions this large at
or near the surface have been known to affect radio propagation.

U.S. To Test 700-Ton Explosive

By AGENCE FRANCE-PRESSE


 The U.S. military plans to detonate a 700 ton explosive charge in a
test called "Divine Strake" that will send a mushroom cloud over
Las Vegas, a senior defense official said March 30.

 The Pentagon plans to detonate 700 tons of conventional high
explosives in Nevada in a June 2 test designed to gauge the
effectiveness of weapons against deeply buried targets, officials said
on March 30.

I don't want to sound glib here... but I'm wondering which method of
delivery they're planning for a 1.4M+ pound weapon.  That's explosive
in this test excluding any case or fuse.

Max. Takeoff Weight for a C-5A is 384.5 tons.
