▲ Earthquakes M2.0+ for the selected day · M4.5+ in 7-day view (USGS live)
EQ button toggles day / 7-day / off · width + color = magnitude (M2 M3 M4 M5 M6+) · length = depth
★ red = event in a named region on its forecast day · ★ blue = within ±3 days · star size = credited loading · ☆ hollow = in the day's listed corridor but under the day bar — less than half that day's top loading (shown, not scored)
Calendar shows every day: ●● = both sources discharged (high-confidence) · ●○ = one source · QUIET = no discharge, observation only — map shows base terrain and live earthquakes, nothing is forecast or scored on those days
Count badge: events in the selected window · % of the 30-day rolling daily average of global M2.0+ counts (30 complete UTC days ending 3 days ago, to sidestep catalog latency) · PACE = count vs. the average prorated to the fraction of the window elapsed so far
PLATES button: red plate boundaries (USGS / Bird 2003 PB2002) — ▲ teeth = subduction / collision, teeth on the overriding plate · ═ double line = spreading ridge or rift · — single line = transform (strike-slip). Brown dashed = Canary registered corridors
AXIS button: A-ANTIPODE lines = azimuth antipode — family-conjugate pairing (ALSK–CHILE · CASC–INDO · KAM–SCOTIA · JPN–MIDAM), not the exact geometric antipode; naming one end credits both. Bold dashed = axis named on the selected day (combined loading shown); faint = not named that day
