Analysis of satellite imagery of the Punggye-ri Nuclear Test Facility acquired during 2019 and more specifically on September 23rd and October 9th, 2019 shows the facility in caretaker status, likely being maintained by security personnel. While there is no evidence of current efforts to restore any of the nuclear test portals, several observations lead us to believe the facility has not been permanently disabled and that the detonations in May 2018 are not necessarily irreversible.
