Across border, residents tell of strong tremor, loud bang

What the Democratic People's Republic of Korea claimed was a "successful hydrogen bomb test" brought a jolt on Wednesday morning to residents of Hunchun, a border city in Jilin province that is near the test site.

A woman who manages a farm equipment station in Hunchun's Fusong township and who wished to be identified only as Lei told China Daily that she felt a tremor around 9:30 am when she was in her office.

A desk, chair and flowerpot on the windowsill shook, Lei said, adding that the jolt lasted about three seconds, stopped for two seconds and then restarted for another three seconds.
