A North Korean nuclear test site recently shuttered by Pyongyang is unusable and will cause a catastrophe if another test occurs, according to a new report.

Chinese scientists studying the damage at the Punggye-ri facility estimate that another test at the facility will lead to “environmental catastrophe,” The Wall Street Journal reports.

Scientists say North Korea's most recent test caused a partial collapse of a cavity inside the mountain facility, which would be further exacerbated by another blast, the newspaper added.

“The occurrence of the collapse should deem the underground infrastructure beneath mountain Mantap not be used for any future nuclear tests,” reads an abstract for the study published by the University of Science and Technology of China, according to the Journal.

North Korea experts at Johns Hopkins University, however, told the Journal that parts of the facility could still be fully functional and that testing could resume.
