Summary of geologic effects of the Boxcar event, Nevada Test Site
Dayton Delbert Dickey, F. A. McKeown, William L. Ellis
1969, Open-File Report 69-74
A high-yield underground nuclear explosion at the U20i site, formed a sink 1,000 feet in diameter above the explosion point. Fractures opened as far as 20,000 feet from the explosion and rock-falls occurred as far as 15 miles. Most fractures were coincidental with north-trending naturally occurring faults. Maximum displacement along...
