You're incorrect or confused on several aspects so let me break it down for you. Frequency of detection of secondary cosmic radiation is very sensitive to geomagnetic conditions. That is not up for dispute. The paper in question provides statistical evidence that "variations of secondary cosmic ray detection rates are periodically correlated with future global earthquake magnitude sum". The paper contains no claims about precisely predicting seismic activity in terms of geographic location or time of occurrence. The authors make this abundantly clear. The USGS page you linked has no citations or even a timestamp. I'd wager it hasn't been updated in ages. It's not the decisive source you want it to be. Here's the paper in question if you want to actually read it: https://arxiv.org/ftp/arxiv/papers/2204/2204.12310.pdf https://arxiv.org/ftp/arxiv/papers/2204/2204.12310.pdf Take a look at this research from NASA, it is one of the many papers that completely contradicts your claim that "changes in geomagnetism are not associated with earthquakes": https://www.scirp.org/journal/paperinformation.aspx?paperid=82421 https://www.scirp.org/journal/paperinformation.aspx?paperid=...
