Theory 25/Sensitivity vs Specificity/Seismic monitoring
Dense Networks Hear Noise
The claim
Seismic networks trade detection sensitivity against false event rate, so adding low-quality stations raises detections and misclassifications together.
01Mechanism
Lower detection thresholds admit more small events and more noise artefacts; discrimination requires quality, not count.
02Prediction
False rate should rise with network density.
03Refutation
False rate independent of density would remove the trade-off.
