Did North Korea Test a Nuke?
I'm skeptical for two reasons:
If the test occured and the administration knows it happened they have to explain why the news hasn't been made public.
"Atomic Activity in North Korea Raises Concerns"
"Blast, Mushroom Cloud Reported in N. Korea"
UPDATE: I know little about seismographs, but a number of Alaska stations, Sand Point, Unalaska, Nikolski, and False Pass recorded an event at around 8:00 a.m. local time on 09.09. There's no indication in the AP story of what time the North Korean explosion happened.
UPDATE II: A reader pointed out a Reuters article where Chung Dong-young, South Korea's unification minister said his government doesn't think the explosion was nuclear. Someone with the title "unification minister" might have an incentive to spin a possible nuke test, but neither the South Koreans, the Japanese, nor the Chinese have said anything. One would think an event this potentially destablizing would bring leaders out before cameras and reporters.
