▬ Σ EI (loading)▬ Σ SRI (release)gap = stored debt
—
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.
