Short answer
Not a single studyNo clear answer.
The article covers a research area rather than reporting a specific new paper, so there is no single study to check it against.
Checked against the study summary. The full text wasn't available, so some details couldn't be settled either way.

Claim 1 of 6Not checkedGeologists found evidence that North Korea’s underground nuclear tests at Mount Mantap reactivated previously quiet faults and set off hundreds of earthquakes that continued to intensify years after the final test in 2017.View evidenceHide evidence
As statedhundreds of earthquakes
Not checked
NewsLink could not identify one source study, so this claim was not compared against a paper.
Claim 2 of 6Not checkedThe final Punggye-ri nuclear test on 3 September 2017 was estimated at 100 to 250 kilotons and produced a magnitude 4.1 collapse event 8.5 minutes later.View evidenceHide evidence
As stated100 to 250 kilotons; magnitude 4.1
Not checked
NewsLink could not identify one source study, so this claim was not compared against a paper.
Claim 3 of 6Not checkedUsing matched-filter detection on 17 years of seismic recordings from stations in China and South Korea, the researchers identified 1,399 earthquakes, including 955 that they could precisely locate.View evidenceHide evidence
As stated1,399 earthquakes; 955 precisely located
Not checked
NewsLink could not identify one source study, so this claim was not compared against a paper.
Claim 4 of 6Not checkedThe earthquakes were not scattered randomly but mapped two roughly parallel north-northwest structures, one linked to a projected continuation of a mapped fault and the other to an unmapped fault-like pattern.View evidenceHide evidence
Not checked
NewsLink could not identify one source study, so this claim was not compared against a paper.
Claim 5 of 6Not checkedThe article says the researchers interpret the pattern as evidence that repeated nuclear tests altered the mechanical balance of a heterogeneous crust already close to failure, rather than the seismic waves themselves persisting for years.View evidenceHide evidence
Not checked
NewsLink could not identify one source study, so this claim was not compared against a paper.
Claim 6 of 6Not checkedThe paper was published in Science, and the authors caution that the apparent long-lived seismic effects broaden the monitoring window but do not by themselves prove causality or rule out that some earthquakes might have occurred without the tests.View evidenceHide evidence
Not checked
NewsLink could not identify one source study, so this claim was not compared against a paper.
Method layer
No single source study was found.
NewsLink still surfaces nearby research so you can inspect the field instead of a single paper.
