Frequency distribution of the number of analyzed teleseismic events within moving time windows. Frequency distribution of the number of analyzed teleseismic events for the 100 to 200 s vertical component at all the target stations within (a) a 30-day and (b) a 60-day time window with the 1-day step (gray bars). Solid lines represent cumulative frequencies in order from the larger number.
