(a) Phase angle frequency variation for seismic events in the period 1600 days before the Wenchuan M 8.0 earthquake in Subregion 2. The fine solid curve denotes a function of sinusoidal least squares fit to the variation. (b) Phase angle frequency variation for seismic events in the period 1000 days (i.e. the most strongly-triggered period) before the Wenchuan M 8.0 earthquake in Subregion 2. The fine solid curve denotes a function of sinusoidal least squares fit to the variation. (c) Phase angle frequency variation for seismic events in the period between 1600 to 11000 days before the Wenchuan M 8.0 earthquake in Subregion 2. The fine solid curve denotes a function of sinusoidal least squares fit to the variation.
