Short-term ±5–15 cm oscillations are tidal residuals and are NOT geophysical. Week-to-month trends reflect true magmatic inflation/deflation. Source: PMEL/OOI · Rick Thomson tidal model · Updated once daily.

      Blue = total stress the system has loaded into this zone since Mar 1.
      Amber = total earthquakes actually released.
      The gap between them is energy sitting quietly in the crust — loaded but not yet discharged.
      A wide gap means the zone is under pressure. When the amber line catches the blue line, the zone has released what was loaded.
      Cascadia's gap never closes — the fault is locked.
