Fig. 2: Statistically segmented timeseries of mean scaled post counts.

Timeseries for 〈eldgos〉 and 〈erupción volcánica〉 are shown in (a and b), respectively. Each consecutive shaded region has internally consistent statistical properties, and each transition between segments is a statistically determined changepoint. The mean value of each segment is annotated (2 s.f.). Note logarithmic y-axes. 'Quiescent' periods are denoted by A, B, etc. The value n indicates the number of segments determined for a given β value.
