A daily measure of
how much seismic energy is being introduced into the Pacific tectonic arc — scored 0 to 100.
Think of it like a barometer for the planet's tectonic stress. When the index is high, the arc is under greater strain and the probability of significant earthquake or volcanic activity increases. When it's low, the system is in a quieter phase.
The index is derived from
geo-seismic energy data and is calculated
months in advance — something no other public forecast system offers.
80–100 · HIGH ALERT — Elevated risk window. Watch for M6+ activity.
60–79 · SHAKEY — Above-average energy. Arc is active.
40–59 · WEAK — Moderate energy. Normal background activity.
0–39 · QUIET — Low energy. Arc is in a rest phase.
