IODSThe Center for Strategic and International Studies (CSIS) Korea Chair has released a new Beyond Parallel analysis, featuring satellite imagery of North Korea’s Punggye-ri Nuclear Test Facility, acquired on April 2, 2024.

CSIS satellite imagery shows that the road leading into the portal for Tunnel No. 3 of the facility has been cleared of snow, indicating continuing low-level activity within the tunnel. At a minimum, this indicates that North Korea continues to be committed to maintaining the progress already achieved in the reenabling of Tunnel No. 3 and the general health of the facility.

Any activity in or around Tunnel No. 3 is always of concern as both the United States and South Korea have assessed North Korea as having completed all the required preparations for conducting a seventh nuclear test from the tunnel. No activity of significance is observed at the collapsed portals to Tunnels No. 1, 2, and 4.
