From: Short-term detection of volcanic unrest at Mt. Etna by means of a multi-station warning system
ROC curve choosing Strombolian activity as onset of the unrest (Table SI2). The Area Under the Curve (AUC; grey field) is ∼0.8. The diagonal of the curve (dashed line) marks the results of random behavior (AUC = 0.5).
