Cannikin, largest underground thermonuclear test

Cannikin was detonated on November 6, Amchitka island, Alaska, 1971, as the thirteenth test of the Operation Grommet (1971--1972) underground nuclear test series. The announced yield was 5 megatons (21 PJ) -- the largest underground nuclear test in US history. (Estimates for the precise yield range from 4.4 to 5.2 megatons or 18 to 22 PJ). The ground lifted 20 feet (6 m), caused by an explosive force almost 400 times the power of the Hiroshima bomb. Subsidence and faulting at the site created a new lake, over a mile wide. The explosion caused a seismic shock of 7.0 on the Richter scale, causing rockfalls and turf slides of a total of 35,000 square feet (3,300 m2). Though earthquakes and tsunamis predicted by environmentalists did not occur, a number of small tectonic events did occur in the following weeks, (some registering as high as 4.0 on the richter scale) thought to be due to the interaction of the explosion with local tectonic stresses.

10. That was me coming on my ex gf after we broke up. We were having troubles and we broke up after 3 years. 3 weeks later she invited me for diner and in the conversation she told me she wanted to do it with more men... I was looking at her like... what is she talking about? and then she told me... can we have sex as friends? and I kept listening... a week later she came to visit me to "print" something. I mean, she was 5'7, super long legs and had this super tiny mini skirt. She turned me on so bad. We had sex like animals from 7pm til 2am, I came like 7 times. What was the difference? sex with no commitment! PERFECT! It felt like that explosion several times.
