Two minor tremors were detected on Saturday, Dec. 9, from near North Korea’s nuclear test site and were probably aftershocks from the country’s massive nuclear test in early September, a U.S. Geological Survey official said.
The aftershocks, of magnitude 2.9 and 2.4, were detected at 0613 and 0640 GMT (1:13 a.m. and 1:40 a.m. EST) respectively, said the USGS and Lassina Zerbo, executive secretary of the Vienna-based Comprehensive Nuclear-Test-Ban Treaty Organization.
