SHANGHAI/SEOUL — China's earthquake administration said on Saturday it had detected a magnitude-3.4 earthquake in North Korea that was a "suspected explosion."

The administration said in a statement on its website that the quake, which occurred about 4:30 p.m., was recorded at a depth of zero kilometers.

Previous quakes from North Korea have indicated nuclear tests by the reclusive state, the most recent earlier this month. The quake was centered near North Korea's nuclear test site.

South Korea's weather agency said it was analyzing the nature of the quake and its initial view was that it was a natural earthquake.
