Evidence for a Possible Weak 1–2 Year Quasi-Periodic Variability Band in Enceladus Plume Activities

Enceladus exhibits persistent cryovolcanic plume activity driven by tidal forcing and internal energy dissipation. Previous studies have primarily focused on short-timescale variability, including orbital tidal modulation, plume brightness fluctuations, and local jet dynamics. However, the possibility of longer-timescale organized variability remains insufficiently explored. In this exploratory note, we construct a composite plume activity index (X(t)) from normalized proxies

Yellowstone Volcanic-Seismic Activity Status (1984-2025)

Using a consistent spatial window centered on Yellowstone (44.615°N, -110.6°W; radius 80 km), we analyzed the Seismicity Index S time series from 1984-2025 at multiple magnitude thresholds and time scales (annual/monthly/weekly). S exhibits a persistent long-term increase that remains present when smaller earthquakes are excluded (M≥2.0 and M≥2.5). This indicates that the observed intensification is not solely an artifact of small-event catalog completeness. Importantly, the
