Magnitude signatures for the three anomaly areas: A1, A2, and A3. Broken and bold lines indicate the normal period and the anomalous period, respectively. (a) Plot of magnitude vs. cumulative number. (b) Plot of magnitude vs. frequency. (c) Plot of magnitude vs. Z-value. The label “M & below” on the horizontal axis in (c) means that the Z-values are calculated for earthquakes with a magnitude equal to, or less than, the values indicated on the axis scale.
