Fig. 6: Overlain vertical component acceleration time series (61-day smoothing) for station clusters and all stations.
From: Increasing ocean wave energy observed in Earth’s seismic wavefield since the late 20th century
Microseism acceleration time series clusters are defined from the associations shown in Fig. 5 and are normalized by respective station medians (Supplementary Fig. 4). Figure 7 shows corresponding 3-year smoothed time series. Black time series show the median of all smoothed time series for each subfigure. ENSO and SOI indices (Supplementary Fig. 7) scaled by seismic data are plotted in red within associated SWP and SEPSWA clusters, respectively.
