The U.S. Geological Survey Web site recorded a light 4.2-magnitude earthquake in North Korea at 10:35 a.m., about 385 kilometers (240 miles) northeast of the North Korean capital, Pyongyang.
South Korean intelligence officials said a seismic wave of magnitude-3.58 had been detected in North Hamkyung province, according to Yonhap.
The test site is the world's largest, occupying an area of over 100,000 sq km, with over 2,000 km of highways. Commercial satellite imagery shows that about 20,000 sq km have been used for testing. No duplicate facility was ever built under the "Third Line." Also the site for China's nuclear weapons training. Possibly also the location of a nuclear weapons stockpile. The headquarters of the test base is in Malan, about 125 km northwest of Qinggir.
