Two small aftershocks were detected Saturday, just a few months after North Korea’s most powerful nuclear test. On September 3rd, North Korea had tested an H-Bomb that was estimated to be 10 times more powerful than the device dropped on Hiroshima during World War II. A United States Geological Survey Official said the tremors were probably the result of the nuclear testing conducted by North Korea.
The official stated:
“They’re probably relaxation events from the sixth nuclear test,”
“When you have a large nuclear test, it moves the Earth’s crust around the area, and it takes a while for it to fully subside. We’ve had a few of them since the sixth nuclear test.“
Measurements of the two movements came in at magnitudes of 2.9 and 2.4, which was announced by the executive secretary of the Nuclear-Test-Ban Treaty, Lassina Zerbo. She then confirmed on Twitter that the quakes were “tectonic” in nature. A series of these disruptions have occurred since testing in September, and South Korean spy agencies fear more tests are to come amid reports that two more tunnels are being readied for use.
