Ternary plots for the EQ–T–N classification. Each cross mark represents the output probability for a given event. a Ternary plot highlighting the EQ–T–N classification regions. The blue, red, and gray regions correspond to the predicted EQ, T, and N labels, respectively. b Ternary plot for events with actual EQ labels. c Ternary plot for events with actual T labels. d Ternary plot for events with actual N labels. Events #1–#10 denote events for which the predicted labels are different from their actual labels (Table 1 and Additional file 1: Fig. S1). eX-component spectrograms and seismograms of the events with different actual and predicted labels
