Looks like epicenter was very close to the 2006 nuke test:

It occurred at the geographic coordinates 41°17′38.4″N 129°08′2.4″E / 41.294°N 129.134°E / 41.294; 129.134 with a horizontal location uncertainty of ±9.6 km (6.0 miles). This is 73 km (45 miles) north of Kimchaek, 90 km (55 miles) southwest of Chongjin, 180 km (112 miles) south of Yanji, and 385 km (240 miles) northeast of Pyongyang.[36]

Yes, they did it in the same area. It is KILCHU. They did it underground in the same mountain.

In 2006, they did it on the East side of that mountain (in a tunnel, they crammed the firecrackers in there), and the intel I have is that this time they did it in the same tunnel, but packed it in from the West. Also this explosion is LARGER than their test under the Bush Administration in 2006.

ROK on national alert. DPRK News has carried the report. Japan government going into alert as well. Reports are streaming in. 11+35 p.m. Eastern Time Sunday
